[PHP] PHPDoc way to describe the magic getter/setters [SOLVED]
I use a base.class that most classes extend from. That class uses the lovely
Magic Methods for overloading __get() and __set()
http://php.net/manual/en/language.oop5.magic.php
However (in Zend Studio for example) when I try to auto-assist a property
$foo I don't see that it has a get() or set() method.
I'd like to see something like $this-get_foo() or $this-set_foo() and
also if possible have them show up in the Outline tab window.
Then I randomly stumbled upon this PHPDoc @ method tag and my whole world
is brighter today than it has been for the past, oh let's say DECADE!
http://manual.phpdoc.org/HTMLSmartyConverter/PHP/phpDocumentor/tutorial_tags
.method.pkg.html
or @property too.
http://manual.phpdoc.org/HTMLSmartyConverter/PHP/phpDocumentor/tutorial_tags
.property.pkg.html
*giddy!*
(now I just have to go back through all my code and update the class
documentation headers everywhere)
?php
/**
* This is an example of how to use PHPDoc to describe the magic __get() and
__set()
* so that Zend Studio / Eclipse / Other IDEs can utilize the methods that

class foo
{
/**

*/
protected $name;
public function __construct($id = NULL)
{
}
}
$myobj = new foo();
Put your cursor after the - and hit CTRL+SPACE.
Notice how you have magic get_name() and set_name($name)
appearing and also in the Eclipse Outline pane
$myobj-
You're welcome.

You are assigning a reference to $v. In the next iteration of the loop, $v
will be pointing at the next item in the array, as will the reference
you're
storing here. With this code I'd expect $new_tmp_results to be an array
where the keys (i.e. the IDs) are correct, but the data in each item
matches
the data in the last item from the original array, which appears to be
what
you describe.
unset($this-tmp_results[$k]);
Doing this for every loop is likely very inefficient. I don't know how the
inner workings of PHP process something like this, but I wouldn't be
surprised if it's allocating a new chunk of memory for a version of the
array without this element. You may find it better to not unset anything
until the loop has finished, at which point you can just unset($this-
tmp_results).
/*
if ($i++ % 1000 == 0)
{
gc_enable(); // Enable Garbage Collector
var_dump(gc_enabled()); // true
var_dump(gc_collect_cycles()); // # of

gc_disable(); // Disable Garbage Collector
}
*/
}
$this-tmp_results = $new_tmp_results;
//var_dump($this-tmp_results); exit;
unset($new_tmp_results);
}
Try this:
private function _normalize_result_set()
{
// Initialise the temporary variable.
$new_tmp_results = array();
// Loop around just the keys in the array.
foreach (array_keys($this-tmp_results) as $k)
{
// Store the item in the temporary array with the ID as the key.
// Note no pointless variable for the ID, and no use of !
$new_tmp_results[$this-tmp_results[$k]['id']] =
$this-tmp_results[$k];
}
// Assign the temporary variable to the original variable.
$this-tmp_results = $new_tmp_results;
}
I'd appreciate it if you could plug this in and see what your memory usage
reports say. In most cases, trying to control the garbage collection
through
the use of references is the worst way to go about optimising your code.
In
my code above I'm relying on PHPs copy-on-write feature where data is only
duplicated when assigned if it changes. No unsets, just using scope to
mark
a variable as able to be cleaned up.
Where is this result set coming from? You'd save yourself a lot of
memory/time by putting the data in to this format when you read it from
the
source. For example, if reading it from MySQL, $this-
tmp_results[$row['id']] = $row when looping around the result set.
Also, is there any reason why you need to process this full set of data in
one go? Can you not break it up in to smaller pieces that won't put as
much
strain on resources?

There were reasons I had the $id -- I only showed the relevant parts of the

There is other processing that had to be done too in the loop and that is

You could save another, relatively small, chunk of memory by crafting your
loop with the rewind, key, current and next methods (look them up to see
what they do). Using those you won't need to make a copy of the array keys
as done in the above line. When you've got the amount of data you're
dealing
with it may be worth investing that time.

array_pop($g); // there is an extra ''

Then remove that from the string before you explode.
Munging arrays is
expensive, both computationally and in terms of memory usage.
$this-tmp_results[$k]['g'] = $g;
Get rid of the temporary variable again - there's no need for it.
$this-tmp_results[$k]['g'] = explode('|', trim($this-
tmp_results[$k]['genres'], '|'));
Maybe an option. I'll look into trim() the last | off the tmp_results in a
loop at the top. Not sure if changing the variable will have the same effect
as adding one does. Interesting to see...
If this is going in to a class, and you have control over how it's

you have the ability to do this when the value is accessed. This means you

Awesome.
No matter what I tried however it seems that frustratingly just the
simple
act of adding a new hash to the array is causing a significant memory
jump.
That really blows! Therefore my solution was to not store the $g as
['g']
--
which would seem to be the more efficient way of doing this once and re-
use
the array over and over, but instead I am forced to inline rip through
and
explode() in three different places of my code.
Consider what you're asking PHP to do. You're taking an element in the
middle of an array structure in memory and asking PHP to make it bigger.
What's PHP going to do? It's going to copy the entire array to a new
location in memory with an additional amount reserved for what you're
adding. Note that this is just a guess - it's entirely possible that PHP
manages it's memory better than that, but I wouldn't count on it.
We get over 30,000 hits per second, and even with lots of caching, 216MB
vs
70-96MB is significant and the speed hit is only about 1.5 seconds more

[PHP] refernces, arrays, and why does it take up so much memory?
I'm confused on how a reference works I think.
I have a DB result set in an array I'm looping over. All I simply want to do
is make the array key the id of the result set row.
This is the basic gist of it:
private function _normalize_result_set()
{
foreach($this-tmp_results as $k = $v)
{
$id = $v['id'];
$new_tmp_results[$id] = $v; //2013-08-29 [dv] using a
reference here cuts the memory usage in half!
unset($this-tmp_results[$k]);
/*
if ($i++ % 1000 == 0)
{
gc_enable(); // Enable Garbage Collector
var_dump(gc_enabled()); // true
var_dump(gc_collect_cycles()); // # of elements
cleaned up
gc_disable(); // Disable Garbage Collector
}
*/
}
$this-tmp_results = $new_tmp_results;
//var_dump($this-tmp_results); exit;
unset($new_tmp_results);
}
Without using the = reference, my data works great:
$new_tmp_results[$id] = $v;
array (size=79552)
6904 =
array (size=4)
'id' = string '6904' (length=4)
'studio_id' = string '5' (length=1)
'genres' = string '34|' (length=3)
6905 =
array (size=4)
'id' = string '6905' (length=4)
'studio_id' = string '5' (length=1)
'genres' = string '6|37|' (length=5)
However it takes a stupid amount of memory for some unknown reason.
MEMORY USED @START: 262,144 - @END: 42,729,472 = 42,467,328 BYTES
MEMORY PEAK USAGE: 216,530,944 BYTES
When using the reference the memory drastically goes down to what I'd EXPECT
it to be (and actually the problem I'm trying to solve).
MEMORY USED @START: 262,144 - @END: 6,029,312 = 5,767,168 BYTES
MEMORY PEAK USAGE: 82,051,072 BYTES
However my array is all kinds of wrong:
array (size=79552)
6904 =
array (size=4)
'id' = string '86260' (length=5)
'studio_id' = string '210' (length=3)
'genres' = string '8|9|10|29|58|' (length=13)
6905 =
array (size=4)
'id' = string '86260' (length=5)
'studio_id' = string '210' (length=3)
'genres' = string '8|9|10|29|58|' (length=13)
Notice that they're all the same values, although the keys seem right. I
don't understand why that happens because
foreach($this-tmp_results as $k = $v)
Should be changing $v each iteration I'd think.
Honestly, I am baffled as to why those unsets() make no difference. All I
can think is that the garbage collector doesn't run. But then I had also
tried to force gc() and that still made no difference. *sigh*
I had some other cockamamie idea where I'd use the same tmp_results array in
a tricky way to avoid a second array. The concept being I'd add 1 million
to the ['id'] (which we want as the new array key), then unset the existing
sequential key, then when all done, loop through and shift all the keys by 1
million thereby they'd be the right index ID. So add one and unset one
immediately after. Clever right? 'cept it too made no difference on memory.
Same thing is happening as above where the gc() isn't running or something
is holding all that memory until the end. *sigh*
Then I tried a different way using array_combine() and noticed something
very disturbing.

{
if (!$this-tmp_results || count($this-tmp_results) 1)

{
$id = $v['id'];

{
$g = explode('|', $v['genres']);
$this-tmp_results[$k]['g'] = $g; //this causes a
massive spike in memory usage
}
}
//var_dump($tmp_keys, $this-tmp_results); exit;

[PHP] need some regex help to strip out // comments but not http:// urls
I'm adding some minification to our cache.class.php and am running into an
edge case that is causing me grief.
I want to remove all comments of the // variety, HOWEVER I don't want to
remove URLs...
Given some example text here with carefully crafted cases:
// another comment here
iframe src=http://foo.com;
function bookmarksite(title,url){
if (window.sidebar) // firefox
window.sidebar.addPanel(title, url, );
else if(window.opera window.print){ // opera
var elem = document.createElement('a');
elem.setAttribute('href',url);
elem.setAttribute('title',title);
elem.setAttribute('rel','sidebar');
elem.click();
}
else if(document.all)// ie
window.external.AddFavorite(url, title);
}
I've tried so many variations and hunted on StackOverflow, Google, etc. and
what would seem like a task already solved, doesn't seem to be.
This is close, but still matches //foo.com (omitting the : of course)
\s*(?!:)//.*?$ (count it as '/m' multiline)
This ultimately ends up in a PHP line of code like so:
$sBlob = preg_replace(@\s*//.*?$@m,'',$sBlob);
Here are some other links of stuff I've found and tried to experiment with
varying degrees.

From: David Harkness [mailto:davi...@highgearmedia.com] We have been using a native jsmin extension [1] which does a lot more without any trouble for over two years now. It's much faster than the equivalent PHP solution and is probably tested by a lot more people than a home-grown version. You might want to check it out before going too far down this path. Good luck, David [1] http://www.ypass.net/software/php_jsmin/ I appreciate the pointer, but our files, like many people, is a mixture of HTML, PHP and JS in one file. This jsmin appears to only work on .js files right? Also, everything else works great in our minifing method, just this edge case. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] How do I remove a string from another string in a fuzzy way?
We have a support ticket system we built and customers can reply via email
which then posts their reply into our database. The problem is that when you
read a ticket, you see each ticket entry (row in DB) but they tend to
accumulate the previous entries text since the customer replied to an email.
A thread if you will.
I'm trying to strip out the duplicate parts (cosmetically on the front end
via a checkbox, in case the support person needs to see the actual unaltered
version such as in cases where the algorithm may be too aggressive and rip
out important pieces inadvertently).
One challenge I'm running into are situations like this, where the text is
embedded but has been slightly altered.
ENTRY 1:
For security and confidentiality reasons, we request that all subscribers
who are requesting cancellation do so via the website of the company billing
their account. You can easily cancel your membership on our billing agent
website
(just in case THIS PHP list software mangles the above, it is just one long
string with no CR breaks as the ones below have)
ENTRY 2: (which was mangled by the customer's email client most likely and
formatted for 72 chars)
For security and confidentiality reasons, we request that all
subscribers who are requesting cancellation do so via the website of
the company billing their account. You can easily cancel your
membership on our billing agent website
This is a simple example, but the solution logic might extend to other
things such as perhaps a prefix like so:
ENTRY 3: (again mangled by email client to prefix with marks)
For security and confidentiality reasons, we request that all
subscribers who are requesting cancellation do so via the website of
the company billing their account. You can easily cancel your
membership on our billing agent website
Keep in mind those blobs of text are often embedded inside other text which
I *do* want to display.
Initially I was thinking that somehow I could use a simple regex on the
needle and haystacks to strip out all white space and str_ireplace() them
that way, but then I don't have a way to put the whitespace back that I can
see.
Currently I'm just sort of brute forcing it and comparing the current
message to previous ones and if the previous message is found in this
message, then blank it out. But this only works of course if they are
identical.
?php
$i = 0;
//the initial ticket message is in a different table than the replies
hereafter
$entry_message[$i] = $my_ticket-get_message(false);
foreach($my_ticket-get_entries() as $eid = $entry)
{
$i++;
$output_message = $entry_message[$i] = trim($entry['message']);
//var_dump('OUTPUT MESSAGE:', $output_message);
for ($j = ($i - 1); $j = 0; --$j)
{
//echo \nbrfont color='green'bsearching for
entry_message[$j] in [i = $i]:/bbr\n$output_message/fontbr\n;
$output_message = str_replace($entry_message[$j], '',
$output_message);
//var_dump('NEW OUTPUT MESSAGE:', $output_message);
}
( ^ you have to start from the bottom up like that or else you have altered
your $output_message so subsequent matches fail ^ )
Would these be helpful?
http://us2.php.net/manual/en/function.similar-text.php
http://us2.php.net/manual/en/function.levenshtein.php
http://us2.php.net/manual/en/function.soundex.php
http://us2.php.net/manual/en/function.metaphone.php
It seems like similar_text() could be, and if it's a high percentage,
consider it a match, but then how do I extract that part from the source
string, since str_replace() requires an exact match, not fuzzy.
I am also thinking maybe something with preg_replace() where I break up the
source string and take the first word(s) and last word(s) and use .*? in
between, but that has its' own challenges for example...
/For .*? website/
On this text doesn't do the match I really want (it stops on the second
line)...
For security and confidentiality reasons, we request that all
subscribers who are requesting cancellation do so via the website of
the company billing their account. You can easily cancel your
membership on our billing agent website
More stuff goes here website
By putting more words before and after the .*? I could get better accuracy,
but that is starting to feel hacky or fragile somehow.

Is your ticketing system written from scratch? Because such type of logic is already implemented in existing help desk softwares. Yes written from scratch years ago. I think you can also use a specific string in your email to define which part goes in ticket and which part not. For example, you can include PLEASE REPLY ABOVE THIS LINE\r\n in each of the email. When reply comes you can split the whole email with this string and get the first part as original reply. We have like 20,000 tickets in there already. Asking the users (who are not the brightest people on the planet to begin with given the vast majority of tickets I've encountered. Most don't read simple instructions as it is and many don't even speak Engrish) to follow some instructions is probably not going to work. And even if it did, that doesn't solve the problem for previous tickets. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Need a tool to minimize HTML before storing in memecache
Well we get about 30,000 page hits PER SECOND.
So we have a template engine that generates a page using PHP/MySQL and
populates it as everyone else does with the generic content.
Then we store THAT rendered page in a cache (memcache pool as well as a local
copy on each server).
HOWEVER, there are of course dynamic parts of the page that can't be cached or
we'd be making a cached page for every unique user. So things like their ?=
$username ?, or maybe parts of the page change based up their membership ?php
if ($loggedin == true) { ?, or maybe parts of the page rotate different
content (modules if you like).
Therefore we are trying to mininimize/compress the cached pages that need to be
served by removing all !-- -- and /* */ and // and whitespace and other
stuff. When you have this much data to serve that fast, those few characters
here and there add up quickly in bandwidth and space. As well as render time
for both apache and the client's browser's parser.

If you really have that much traffic, then memcache isn't your answer to
caching. It is as slow as a fast database.
That's not entirely true.
You should use APC caching instead. APC will also handle a lot of
bytecode caching.
We have both.
If you want to go with tidy and surf around the php issues you could
optimize the single html parts, before glueing everything together.
That would require much more work than simply getting and to work. And
honestly I've been hacking around Tidy so much at this point with regex to
minify the output, that I'm even wondering if Tidy is worth the both anymore.
Not sure what else it will give me.
Maybe google page speed is worth a look for you too?
We have over 1,000 servers in house and also distributed across nodes in
various cities and countries.
With the loggedin flag, you can save two versions of your rendered, one
for loggedin users and for not logged in users. That saves you php code
in your template and you can use tidy. And for any other variables you
can load the dynamic data after the page load.
I gave simplistic examples for the sake of illustration.
With tidy, have you tried
http://tidy.sourceforge.net/docs/quickref.html#preserve-entities
http://tidy.sourceforge.net/docs/quickref.html#fix-uri
Yes. See below. I posted all the flags I have tried and I too thought those
were the key, but sadly not.

My problem is it is not giving the desired performance so want to try the compiler if any. PHP gets compiled to bytecode on the server before being executed. You can cache the precompiled code with (for example) APC. Unless your code is several thousand lines of code (or your server very slow... 486-slow), the compilation phase is not that long. I think your main problem can be one of: 1- wrong algorithm 2- long waits (database, files, network, etc.) 3- heavy calculations Solutions: 1- find and use a different algorithm 2- Try to parallelize code (with gearman or similar, or via pctnl_fork) 3- rewrite the heavy functions in C, C++ or Go and compile them, then call them via PHP extensions or via gearman/fork. Another thing you can do is store both page renders as well as database results in http://memcached.org/ blobs and pull from those in intelligent ways (you can creatively mix and match live stuff with cached stuff and you can make pages expire in defined hours via your cache class or even a crontab). We also add another layer in that if a blob exists in the memecached but not locally, we save it locally for the next hit. Depending on your hardware though the Gigabit/Fiber might be faster access than a local HD/SSD/RAM disk, so YMMV. We use LAMP and our site gets 30,000 hits per SECOND on two servers and 5 pools. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

At the moment, they don't have a wiki or any documentation about their projects. For me, the first challenge in probation period is to understand how their code works. * Considering that there is no wiki or docs, How can I see the Big Picture?* i'm sure this is a common problem for programmers everywhere. What approach do you use in a similar situation? Is there a systematic approach for this? Is there reverse-engineering technique to understand the design of code? Please share your experience and thoughts. -Thanks in advance, Behzad I was in this same situation when I started 2011-03. No wiki. No revision control. No real process. No documentation. They'd push to production by copying files manually. When they wanted to create a new website, they'd clone an existing one and start modifying -- no shared libraries (so they had 50 versions of the same dbconnection.class.php but all just slightly different since that is also where they housed the configuration user/pass/etc.)!! It was a clu$terfsck. Take a day or two to go through every menu item and just see how the thing works from a user POV. You don't have to memorize it, just be familiar with concepts, vocabulary, paths, etc. First thing I did was install Trac http://trac.edgewall.org/ And of course Subversion. I personally recommend the 1.6 branch and not the newer 1.7 that uses sqlite. That version seems to always corrupt, especially on the clients (like in TortoiseSVN). http://subversion.apache.org/ I would use something to visually map out the database. If it's using MySQL, there are free tools like MySQL Workbench. But if they don't use InnoDB tables, it can get painful to draw the lines if it's a large DB. http://www.mysql.com/products/workbench/ I then started to go through code and use PHPDoc for every major function or method, especially in classes or include files where the meaty stuff happens, or very complex portions. I didn't bother with every get_* or set_* unless there was something obscure about them. Although, over a year later, and we have pretty much filled them all in now as the other devs started helping once they saw how easy it is to do a few as you encounter them in your daily coding, and how awesome that integrates with PDT or Zend Studio (amongst other IDEs). We didn't generate an actual PHPDoc Web version, there's really no need. The IDE shows you the important stuff anyways. We're pretty diligent about keeping these PHPDoc comment blocks updated now. http://www.zend.com/en/products/studio/ I then started the long tedious process of merging our various different sites to implement shared libraries (database connections, memecache, various objects, etc.). If you have only one project, then this is less of an issue, but if you have 1 vhost or something then you'll want to do this. All the while I documented useful tips, tricks, explanations, etc. in the Wiki. Referencing source code (which is of course committed at this point). Trac rules in that respect. Xdebug will give you vastly better call stack and var_dump() alone. I don't use the breakpoint stuff myself, but that is another benefit perhaps. http://xdebug.org/ And for the love of [insert deity of your choice here] not EVERYTHING has to be OOP. Use the best tool for the job!! Nothing pisses me off more than having to instantiate a new class just to do some simple method that a standard function would do. If you want to be organized, use static methods then where appropriate, but don't avoid functions just because some book told you that OOP is the king $hit. d -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Joining a team, where no wiki or docs are available
That is a good point. We do not do unit tests here. Nothing against them, it’s just a bit overkill for our needs. We build lots of websites, not one massive SaaS. But I’m not saying do not use OOP. I’m just saying not everything has to be OOP. It’s a subtle but significant difference. We have OOP classes for our database connection (and of course the helper routines), memecache access/purging/etc., and then objects for actors, movies, scenes, search results, HTML templates, email, tickets, etc… again, use the right tool for the job.

JQuery is a LOT of code to include if you're just going to do an AJAX call or two. There are examples of doing straight AJAX with Javascript on the 'Net. Once you work through them, you find that there's a static part that you can include in all the files you want to make AJAX calls.

RE: [PHP] Creating drop-down menus
AJAX. Your page calls a PHP 'ajax' routine that pulls the data, sends it back as a JS array, and you re-populate the second select box. Welcome to the year 2000. Using frameworks like jQuery, this is pretty trivial these days. You're not trading any security since the PHP gets whatever parameters and checks whatever $_SESSION or other authentication and only sends back whatever data is needed.

Sometimes I need to use javascript to fill a drop down box based on the value of a previous drop down box. However, the information to fill the latter is stored in mysql and can be a lot, what I have been doing is that, using PHP, I create hidden fields with all the possible information that might be needed to fill the second drop down. For example, the user chooses a bank from a drop down, and then a list of clients is displayed on the following drop down. I use PHP to read all clients from all the banks and put that as hidden fields on the html page. It is very cumbersome. I do not want to read the database (which changes dynamically) from javascript directly due to confidentiality and because a lot of care has been taken to create the appropriate queries with checks and protect misuse of the information using PHP. My questions are: 1) Do people just normally use hidden fields to store possible information to fill the drop downs? 2) any suggestions?

In my 'includes/common.inc.php' the key things are these:

function php_error_handler($errno, $errstr, ...)
{
//does some stuff
//calls php_custom_error_log()

if ($error = error_get_last())
{
var_dump(LOG_LEVEL, $error);

}

?php
define('LOG_LEVEL', E_ALL ^ E_NOTICE);
error_reporting(LOG_LEVEL);
ini_set('display_errors','On');
define('VM', true);
define('DEVELOPMENT', false);

ini_set('xdebug.var_display_max_depth', 5 );

[PHP] set_error_handler() only triggering every Nth time
I am implementing a custom error handler and started noticing some bizarre
behavior. Every Nth time I refresh the page, I see the error/output.
In my 'includes/common.inc.php' the key things are these:
set_error_handler('php_error_handler');
function php_error_handler($errno, $errstr, ...)
{
//does some stuff
//calls php_custom_error_log()
}
function php_custom_error_log()
{
echo php_custom_error_log : .date('H:i:s');
if ($error = error_get_last())
{
var_dump(LOG_LEVEL, $error);
//does more stuff
}
My test page:
?php
define('LOG_LEVEL', E_ALL ^ E_NOTICE);
error_reporting(LOG_LEVEL);
ini_set('display_errors','On');
define('VM', true);
define('DEVELOPMENT', false);
ini_set('xdebug.var_display_max_children', 1000 );
ini_set('xdebug.var_display_max_depth', 5 );
require_once 'includes/common.inc.php';
## BEGIN TEST #
foreach($empty as $k) echo $k;
?
For those astute observers, you'll note that $empty is not an array and
therefore I expect an error message (well warning)

[PHP] How do I enable more useful PHP error logging?
My question is, is there a way to enable some PHP configuration that would
output more verbose information, such as a backtrace or the URL attempted?
In our PHP error log, we have the usual semi-useful information. However
this is only a partial story as it's hard to re-create the URL that caused
the error. In the first Actor example, yeah actor_id 2206 doesn't exist and
so now I have put a try/catch on all pages that have new Actor($actor_id)
but it doesn't tell me WHY this is happening. How did someone get to this
point? I doubt they just randomly picked '2206' which happens to be one of
only a handful of actually missing actors out of 100k. Sure I guess it could
be a bot that sequentially tried them all, but this is not likely since we
have SEO style URLs and so we re-map an actor name back to the ID. So the
bot would have to try NAMEs not IDs. This means we must have some link
somewhere that points to this. Same with the common foreach() warnings
below. Yeah, the array being passed is empty/null. Sure I can check the
array before doing the foreach() or even @foreach() but that doesn't tell me
the root cause. What video are they trying to access that has no scenes or
invalid actors?
We do NOT have apache logging turned on as we get 30,000 hits per second and
it would be too expensive. I only care about PHP errors like this. And the
apache error log (which we do have enabled) doesn't have useful info related
to these kinds of issues as they're really not apache's problem. That log
only deals with missing files/images/pages/etc.

RE: [PHP] How do I enable more useful PHP error logging?
-Original Message- From: Stuart Dallas [mailto:stu...@3ft9.com] Seriously? Errors like this should not be getting anywhere near your production servers. This is especially true if you're really getting 30k hits/s. Don't get me started. I joined here almost a year ago. They didn't even have a RCS or Wiki at the time. Nothing was OOP. There were no PHPDoc or even comments in the code. They used to make each site by copying an existing one and modifying it (ie. no shared libraries or resources). I could go on and on. Suffice it to say we've made HUGE leaps and bounds (thanks to me!), but there is only 3 of us developers here and no official test person let alone a test team. It is what it is. I'm doing the best I can with the limited resources available to me. And let me tell you a little secret, when you get to that scale, you see all kinds of errors you don't see on your VM or even with a test team. DB connections go away. Funny things happen to memcache. Concurrency issues arise. Web bots and search engines rape, pillage and ravage your site in ways that make you feel dirty. So yeah, you do hit weird situations and cases you can't possibly test for, but show up in error logs. For a commercial, zero-hassle solution I can't recommend http://newrelic.com/ highly enough. Simple installation followed by highly detailed reports with zero issues (so far). They do a free trial of all the pro features so you can see if it gets you what you need. And no, I don't work for them, I just think they've built a freakin' awesome product that's invaluable when diagnosing issues that only occur in production. I've never used it on a site with that level of traffic, and I'm sure it won't be a problem, but you may want to only deploy it to a fraction of your infrastructure. A quick look at that product seems interesting, but not what I really need. We have a ton of monitoring solutions in place to get metrics and performance data. I just need a good 'hook' to get details when errors occur. If you want a homemade solution, the uncaught exceptions are easily dealt with... CATCH THEM, do something useful with them, and then die gracefully. Rocket science this ain't! Thanks captain obvious. :) I can do that (and did do that), but again, at these scales, all the text-book code you think you know starts to go out the window. Frameworks break down. RDBMS topple over. You have to write things creatively, leanly (and sometimes error on the side of 'assume something is there' rather than 'assume the worst' or your code spends too much time checking the edge cases). Hit it and quit it! Get in. Get out. I can't put try/catch around everything everywhere, it's just not efficient or practical. Even the SQL queries we write are 'wide' and we pull in as much logical stuff as we can in one DB call, get it into a memcache slab and then pull it out of there over and over, rather than surgical queries to get small chunks of data which would murder mySQL. Part of the reason I took this job is exactly because of these challenges and I've learned an incredible amount here (I've also had to wash the guilt off of me some nights, as some code I've written goes against everything I was taught and thought I knew for the past decade -- but it works and works well -- it just FEELS wrong). We do a lot of things that would make my college professors cringe. THAT is the difference between the REAL world and the LAB. ;-) See the set_exception_handler function for an easy way to set up a global function to catch uncaught exceptions if you don't have a limited number of entry points. You can similarly catch the warnings using the set_error_handler function, tho be aware that this won't be triggered for fatal errors. And this is the meat of the solution. Thanks! I'll look into these handlers and see if I can inject it into someplace useful. I have high hopes for this now. But seriously... a minimal level of structured testing would prevent issues like this being deployed to your production servers. Sure, instrument to help resolve these issues now, but if I were you I'd be putting a lot of effort into improving your development process. Contact me off-list if you'd like to talk about this in more detail. See above. I have begged for even a single dedicated tester. I have offered to sacrifice the open req I had for a junior developer to get a tester. That resulted in them taking away the req because clearly I didn't need the developer then and we can just test it ourselves. You're preaching to the choir my friend. I've been doing this for 15+ years at various companies. ;-) d. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Where did my comment go related to lower/upper bounds for any number and offset?
Hey. To anyone that works on the php.net site. I posted this comment:
http://www.php.net/manual/en/language.operators.bitwise.php#107617
And I saw it there shortly after and even sent that link to some colleagues.
Now it's gone on every mirror too. WTF?? :-( It certainly was relevant as it
used and ~.
This is what it said basically (although this is a much longer
version/explanation. The note post only had the code function and results).
We've started to convert more of our queries to a wide mode and take even
more advantage of memcache instead of a thin mode where we hit the DB (and
store in memcache too) for each scene. The idea being that if we make the
queries pull more data than needed (in an intelligent way of course) then we
hit the DB less and memcache more. This works great with the concept of a
DVD vs SCENE as one is macro and one is micro.
I used some bitwise operations to figure out a lower/upper number for any
given number (and offset).
/**
* Get the upper and lower boundaries for any given number and 2^n offset
(other offsets give bizarre results)
*
* @access public
* @return array
* @param integer $number
* @param integer $offset (32) must be a 2^n value [8, 16, 32, 64,
128, ...)
* @author Daevid Vincent
* @date 2012-02-21
*/
function boundaries_ul($number, $offset=32)
{
if ($offset 8) return false; //nothing smaller than this makes
practical sense
if (($offset ($offset - 1)) != 0) return false; //not a 2^n
$offset = $offset - 1;
//zero out least significant bits.
//For example if $offset = 32, then the least 5 bits [16 8 4 2 1] ==
31 == 0xFFE0
$lowerbound = $number ~$offset;
$upperbound = $lowerbound + $offset;
return array('lower_bound'=$lowerbound,
'upper_bound'=$upperbound);
}
for ($i = 0; $i 20; $i++)
{
debug_print($i, 'forloop $i decimal');
$b = boundaries_ul($i, 8);
var_dump($b);
echo hr\n;
}
?
forloop $i decimal = 3
array
'lower_bound' = int 0
'upper_bound' = int 7
forloop $i decimal = 4
array
'lower_bound' = int 0
'upper_bound' = int 7
forloop $i decimal = 5
array
'lower_bound' = int 0
'upper_bound' = int 7
...
forloop $i decimal = 12

'lower_bound' = int 8
'upper_bound' = int 15
forloop $i decimal = 14
array
'lower_bound' = int 8

In the get_like()/get_dislike(), we pull in both at the same time from the
same table, which is great. But we can only pull in by scene_id and not a
whole dvd_id (since we don't have the dvd_id in that table) as many of the
other queries I'm converting. That got me thinking of how can I get more
juice for the squeeze. Given that most scenes (if not all) are sequential
that is a clue.
We use the md5($sql) as the hash for memcache so that's why this works,
since the same 128 scene_id's will all result in the same $sql query string
(thanks to upper/lower bounds) and therefore the same hash key is pulled.
Knowing these 'constants', I then fabricate a query for say scene_id = 21269
var_dump(boundaries_ul(21269, 128));
Which would look something like this:
SELECT `scene_id`, `like`, `dislike` FROM `scene_likes` WHERE `scene_id`
BETWEEN 21248 AND 21375;
The MD5 hash = 801206aca6ee8b908095161db8d77585 . Which is now the same for
ANY of 128 scenes from 21248 through 21375 and therefore all in the same
memcache slab.
Now in code, pull up to 128 rows at a time (since a memcache slab can be
upto 1 MB, this should easily fit)
$b = boundaries_ul($this-id, 128);
$result = $con-fetch_query_pair(SELECT `scene_id`,
CONCAT(`like`,'|',`dislike`) FROM `scene_likes` WHERE `scene_id` BETWEEN
.$b['lower_bound']. AND .$b['upper_bound']);
list($this-like, $this-dislike) = explode('|', $result[$this-id]);
And with a little clever PHP slicing and dicing, I have an index right to
the scene_id and the dis/likes. fetch_query_pair() does just like it sounds,
it returns a hash/array where the $col[0] is the key and $col[1] is the
value since this is such a common thing to do.

Now there's a contradiction. ;-) Anyways, I do agree with Alex though. Setup and maintenance of a five nines server is non-trivial. You might look into one of the cheap hosting services that use VMs to start with. If you out-grow that, it's pretty easy to migrate your VM to iron. A buddy of mine just joined http://www.linode.com and seems to really like it. Having said that, I would STRONGLY suggest you ditch the whole XAMP, WAMP, MAMP, WTF? they call it these days. Setup VirtualBox (it's free and cross platform). Then setup a VM to be as close to EXACTLY as your production environment as possible (sans hardware specs of course). I mean, same distro, same tools, same versions, same configs, same directory structures. Develop on that. Setup a repository (subversion is easy, well supported and battle tested). Then just do an export from SVN to your PROD box.

You also should setup a test VM too. So deploy from DEV to TEST first, let someone (preferably besides yourself) hammer away at that, and once you feel it's stable -- in a few days or week -- push to PROD. You have to let the code 'bake' on test to make sure there are no regression bugs or new bugs. I work for a company now where the CTO (by default since it's his company ;-) ) constantly pushes to PROD too early IMHO. It's bitten us more than once.

It is a standard comparison operator in pretty much any language and would be completely stupid of the PHP Devs to deviate that far from the norm. http://php.net/manual/en/language.operators.comparison.php Plus I love that operator and use it quite frequently. However, I use it like this just for clarity: echo your result is .((1 == 1) ? 'true' : 'false').'br'; Second question: zend studio displays all variables used by a script by clicking the arrow next to te file name. I've used ZS for 4+ years now, and comicaly have never even used those little down arrows next to a file. HAHAH! Good to know. Although it is a little strange as they seem to only be where you use a = assignment. It doesn't know about - or other instances of that variable (like if you echo it or something). But still could prove useful. If you want to display it in runtime, you can: print_r($GLOBALS); Whoa nelly! That prints out WAAY too much information ;-) But thanks. Not sure why I didn't think of that one. Maybe because at one time I did use it, got sensory overload from the amount of data it spews to the page, and then blocked it out of my mind for future use. :) ÐÆ5ÏÐ There are only 11 types of people in this world.

[PHP] Mangling URLs for RewriteRule parsing
I'm fumbling trying to think of a nice easy way to mangle my URLs within PHP
for SEO and apache's RewriteRules magic.
Given a basic rule like this:
RewriteCond ^/foo/movie/genre/([-a-z\|]*)_([-a-z\|]*)/([0-9]+)/videos.html$
RewriteRule /browse_scenes.php?genre_id=${genres:$2}pg=$1%{QUERY_STRING}
[NC,L]
I currently have a wrapper createPageLink() that right now just spits back
the 'ugly' URL style. (ie. the 'Rule' portion), but what I want it to do is
spit back the nice 'Cond' part instead)
Do I just have to make a giant switch/case statement for all the
'browse_scenes.php' and other .php pages?
It seems to me that I should be able to dynamically build the URLs that are
inserted into my .php page (the ones that show up in the browser bottom bar
on hover).
I'm fairly flexible at this point as I'm just starting to do this SEO stuff,
so I thought I'd ask if someone has a nice function or class or something
that has already solved this kind of problem? Or is it such that every site
is unique and no such 'generic' kind of wrapper exists? I guess I'm thinking
of methodology or best practice type code, rather than a turnkey solution if
none exists.

time to share it!

You've been even less helpful than the broken community surrounding
doctrine. Thanks for your effort daevid, I know you tried hard ;)
-nathan
You asked if anyone had experience with Doctrine and to share the experience. I
did just that *wink*. I never claimed to have a solution to your Doctrine
problem, other than the fact that Doctrine is in itself the problem. You are in
a recursive loop. :) Think of me as the return;. You're welcome.
In all my 25+ years of coding experience with any language and especially PHP,
I've learned the hard way that the one-size-fits-all approach of a generic
framework and the bloat of an ORM just doesn't work. It looks wonderful, trust
me, I've fallen prey to its sultry gaze myself. Hell, I've even written tools
that started to look like ORMs and Frameworks, and then there comes a point
when you realize their cost is too high. You're better off (IMHO) making some
very efficient wrapper functions for sql_query(), sql_save() [does
insert/update intelligently], sql_delete(), etc. and not get all fancy with
making a SQL class/object and all that crap either.
OOP is great for many things, but it's not the answer to everything and
developers need to know when to use the right tool for the job. It has also
been my experience that a SQL wrapper is best as a procedural system since it's
called so frequently and often. Doing some silly:
$con = new DBConnection();
$con-query('select * from foo');
$myresults = $con-getResults();
$con-close();
Or whatever is a waste.
$myresults = sql_query('select * from foo');
Is far more efficient and easier to read.
Let the function open a connection, and do all the work.
The ORM dealios complicate things, as now you have some stupid YAML file to
maintain, and you have to make objects that relate to other objects (1:M, M:M,
etc.) and after a while, you start to think, shit, I could have done this with
like 3 SQL statements. The ORM's fatal flaw is it's one-size-fits-all Achilles
heel.
Example: We used to have this crontab job that would update news stories from
RSS feeds we harvested around the web. It was taking HOURS to complete. Mostly
because for each story, we had to create a new Doctrine object thingy and all
the related table objects and then update the instance object, then -save() or
whatever. Do that over a hundred-thousand objects and stuff starts to slow
down. We converted it to use straight SQL calls and it ran in under 10 minutes.
YES. From HOURS to minutes. An order of magnitude faster.
Just trying to save you (and anyone else) the time and trouble. I don’t dislike
ORM and frameworks because I have some axe to grind, like I used to write a
framework and it cheated on me and so I'm all jaded... No. I dislike them from
experience over years of practical real-world implementations. I have tried
them. I *WANT* to like them, I really do. I was very excited when Zend
Framework came out... and then... I used it, and realized it was like the
others. Bloat. Slow. Confusing. Cumbersome.
The last thing I'll leave you with is that, when you start to rely upon one of
these ORM/PHP frameworks, you're not only stuck with it -- warts and all -- but
you have to TRAIN other people to use it as well! If you find a bug, you either
have to maintain it forever in your own branch, or hope the developers of the
framework fix it. When you hire new people, you always have to add some caveat
to the job request, Zend Framework, Doctrine

I used to write my queries by hand, but over time you start to realize that perhaps, maybe writing out thousands of identical lines of code over hundreds of projects might not be an efficient usage of time. I never said to do that. I said to write your own wrappers and your own framework for YOUR needs. A one-size-fits all solution is never going to be as clean or efficient as your own code. See previous rant and I'm sure there are archives of my other rants on the failure that is ORM Frameworks. What is the more common question from clients: why is this so slow, or, client asks why is this not finished yet? ...until the project gains traction and starts to get users and then it will be, why is this so slow?! I do like the half-hearted diatribe against ROR, which I will assume is a wildcard, allow any language/framework combination to stand-in. Yes, frameworks as a whole suck. However, I will concede the one framework I do enjoy and find much more useful is jQuery, if for no other reason than it handles all the minutia and BS of browser incompatibilities and parsing the DOM in JS. It's fairly lightweight and works very well for the most part. Even having said that, I really only use jQuery on a need-to-use basis and not for everything JS related. But once you have to include it in a page for some necessary reason, you might as well continue to use it in the page since you've already downloaded it to the client and it makes the code easier to read vs. jumping in and out of raw JS and jQueryScript(tm) The real take-away message here is that you're trying to paint everything with the brush that you see the world in, while the reality is that not everyone has your requirements. Personally, I don't enjoy If it's a project bigger than your own personal website, then eventually you WILL have my requirements. trying to mess around with ill-conceived, backwards-compatible adhering designs from 12 years ago. I understand that growth is organic and deal with it on a daily basis in my own projects. Hence, I use a framework and other tooling that allows me to complete jobs in a tidy and orderly fashion. Name me some LARGE popular sites that use frameworks? Again, if you want to make your little companies website or personal page, go for it. Frameworks are great for prototypes and simple stuff. Anything more and you're going to hate life after a year or two using it. Fact. If I need something a little more cutting-edge I can always drop down lower on the stack to bypass PHP with other techniques like caching or bypassing the framework altogether

I now have the need to display multiple maps on the same page and from what I can tell I have to create new instances and variables for all of them... What I'm wondering is since I know very little javascript would it be bad to create a PHP function to write the java code for the proper number of maps I need to display? The map info is being pulled from a database where events are being added and could contain 2 or 200 maps... Or should I learn javascript and figure out how to create a loop in there so that I can just loop it in the java and not repeat code? Thanks for any assistance you can give!

I have an email message
$msg = 'Name: $fname ' . ' $lname\n'
. Phone: $phone\n
. Email: $email\n
and it works fine, however in this message there are about 30
variables that
are being called...as such
. Order: beefschnitzel $beefschnitzel\n
. Order: beefstrips $beefstrips\n
. Order: cheesesausage $cheesesausage\n
. Order: crumbedsausage $crumbedsausage\n
. Order: chucksteak $chucksteak\n
. Order: cornedbeef $cornedbeef\n
. Order: dicedsteak $dicedsteak\n
. Order: filletmignon $filletmignon\n
I want to only send the message if the submitter enters an
amount in the
form for the corresponding variable, instead of having a
bunch of empty
messages. So I have been trying to use the empty() function as such:
. if empty($beefolives){''} elseif (isset($beefolives)) {
'Order: beefolives
$beefolives\n'}
You are setting this up fundamentally wrong.
You should be using an array and looping through it.
Something like:
$myorder['cowface'] = 1;
$myorder['beefenweiner'] = 2;
$myorder['chucksteak'] = 1;
foreach ($myorder as $item = $quantity)
{
echo Order: $item x $quantity\n;
}
Then your array only contains the items someone actually puchased and how
many.

RE: [PHP] ORM doctrine
-Original Message- If you value CPU time over developer time, by all means avoid ORM frameworks (and *all* frameworks). The point of a common framework is to trade a small bit of performance for a large amount of developer time. If you will only use the framework once, the payoff will be much less. The goal is to choose frameworks that you can leverage again and again. I disagree. If you use a framework, then you're stuck with it. Bugs and all (and trust me there are bugs and limitations you WILL run into). If it's your code, you can fix it. If it's someone elses' you have to submit a bug report and HOPE they fix it. If they don't you are now forced with either patching every new release or working around it. As for training, you will be able to hire another developer that knows Doctrine. Doubtful. It's hard enough to find skilled PHP developers as it is. Everyone and their mother THINKS they're a LAMP guy. Test them. You quikly find out that buzzwords on a paper resume are not the same as a real developer. It will be impossible to find a developer *anywhere* that understands your home-grown framework without training. That's just it. DO NOT make a framework. Make some helper routines for common tasks like sql_query(), sql_insert(), sql_update(), sql_select_box(), etc. and stick to the basics. Frameworks are a waste of time and energy -- homegrown or off-the-shelf. They try to be all things to all people and turn into a jack of trades, master of none. They're bloated and cumbersome and force you to wedge square pegs into round holes all the time. Nor will you get help with bugs in your framework or be able to discuss better ways to use it on forums. That's what your employees, team-mates, customers, testers, etc. are for... If you're making JoeBlowsRinkyDink.com then go for the framework if you want to play with it for the massochistic experience and to learn your lesson the hard way. But don't use it for paying customers and certainly don't use it in an enterprise level -- it will be the death nail to your project ultimately. Use PHP the way God intended it to be used.

And I'm trying to call it from a PHP page like so:
img src=?php $my_lopa-render_image(); ? alt=Image created by a PHP
script width=200 height=80
But it doesn't show the picture. :\
If I take the contents of that function and dump it into a gdtest.php
file and call it like this however, it does work:
img src=images/gdtest.php alt=Image created by a PHP script
width=200 height=80
So what am I doing wrong above that I can't just call it from my class?

not $this-name and $this-price, which is not what I want.

the values each

Is there any way to assign values to the fields in a class

Maybe I'm missing something, but i thought that's what the constants
evaluated to
In a sloppy way that is accurate, but not sufficient for my needs.
If ($nullvalue)
If ($truebool) ...
But to be more accurate,
$nullvalue != is_null($nullvalue)
$truebool != is_bool($truebool)
$truebool !== TRUE
Etc...
There are subtle but significant differences

I can see uses for either (or both). To me, it seems that an .ini file would be ideal in the case where you want to allow a simpler interface for people installing your app to configure things that need configuring, and an included PHP code configuration file for things you don't necessarily want the average installer to change. What do you think? Tamara We used config.inc.php for the past few years, but as our project is grown and we have several other departments developing portions in several different languages (not JUST PHP) but all wanting to share resources such as database connection information, pathing, email addresses (for error reporting, notifications, etc.), memcache servers, etc. using a PHP file is not an option. It can be a shim however and that's what I've done over the past few days is to parse the .ini and populate the same config.inc.php file with said values so that all the code continues to work. Plus it allows for easy populating in a programatic way if you name your variables right and organize things. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What do you think? Tamara There are potential security concerns involved too. An .ini file will be output as plain text by default by the web server if requested by a user agent unless it is protected somehow (by a .htaccess file for example) or it is outside of document root for the server. A PHP file on the other hand will be parsed, so won't output it's variables. It's all too easy to forget to protect an ini file from this sort of thing, whereas if you've written a website in PHP, it becomes fairly evident if your web server isn't configured for PHP without testing specifically for it! Why would you put your configuration file in a ../htdocs folder? That's just poor design. Just as your classes and include files are OUTSIDE your document root, so must your config file be. Plus it's trivial to secure a .ini with a .htaccess or other apache method. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Sent: Thursday, August 26, 2010 4:53 PM
To: php-general
Subject: [PHP] Making multiple RSS feeds for the blog website
Hi everyone,
We are developing a blog service website.
What we need now is the ability to make multiple RSS feeds from
several pages (an RSS of each user's blog, a feed from each timeline -
timelines are our representation of users' favorites; a feed filled
with comments to a separate entry, etc.). What would be great is the
following: a user enters, say, in my blog and sees the mark that there
are RSS feeds. Then he/she clicks the mark or presses a keystroke
(Alt+J in IE8, for instance), finds the feed and double-clicks on it.
Then he/she can either read the feed or subscribe to it. The feeds
have usually file extensions of .rss or .xml.
Question: how do we do that with PHP?
Thanks!

In otherwords, to paraphrase:
DBAG_MODE
We have this super cool new idea that's going to revolutionize the web and
blogs and cloud computing and we might even create our own new buzzword. We
heard you can do this with PHP. We just don't have any code written, so
could you guys write it for us. That'd be swell. kthxbye.
;-)
Dude. Andre. Let me break it down like a fraction, as to how this list
works.
YOU post some code that you are struggling with, or you post some SPECIFIC
question, and the generous subscribers to this list decide if your question
is worthy of their time to reply.
Your question (for lack of a better term) was devoid of either of those
things.
Now, had you said, How can I formulate an RSS feed?, I might point you to
this:
http://www.phpclasses.org/package/560-PHP-XML-RSS-feed-generator-for-conten
t-syndication-.html
Or if you had said, How does one double click? (since that is NOT a
web-friendly navigation method by default), I might point you in this
direction:
script
onload = function () {
document.getElementById(textarea).ondblclick = function () {
alert('Double Clicked!') }
}
/script
then this in the body
textarea id=textarea/textarea
Or even if you said, How do I steal, er um, read an XML file from another
site? Then someone might show you these functions (since you clearly
missed them when you RTFPM)
http://us2.php.net/manual/en/function.file-get-contents.php
http://us2.php.net/manual/en/ref.simplexml.php
http://us2.php.net/manual/en/book.dom.php
But again, your question was so vague that I (and everyone else) probably
has nowhere to begin to help you and therefore most likely won't. Given the
above advice, you might consider breaking your questions down into PHP
related specific examples.

This was the complete code of the page (this is the POST
version not the REQUEST version):
?php
$response = print_r($_POST, true);
echo $response;
?
Returns an empty array no matter what POST vars are sent. We
fixed it by changing it to this, which I've never even heard
of, but so far is working perfectly:
?php
$response = file_get_contents('php://input');
echo $response;
?
I have no idea what the problem was. Thanks to everyone for your help.

Something like (untested): echo 'password' | mysql -u root -p query You know you can pass that on the command line right and avoid this pipe business? mysql -uroot -ppassword query Or mysql --user=root --password=password query I believe that is the right sort of thing, but I've never quite done it all as a single statement like this before, I've always tended to type in things on a line-by-line basis. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For example, let's say the investigator has a piece of paper that has the number 393 on it and want's to search the database for all phone numbers that contain 393 -- he could use %LIKE% and that would produce 517-393-, 393-123-4567, 818-122-4393 and so on. That's neat! However, if the field is encrypted, then how do you preform a partial search on that? You can't encrypt the search string and use that because you need the entire string. So, how do you solve that problem? If you hash the number of store the hash, then you can create a hashed search string and use that. But again it doesn't work for partial %LIKE% searches. For example, I couldn't search for 393 in a SS# -- I would have to search for the complete SS#. So, how do you solve the %LIKE% problem with encryption and hashes? Well, if you can get all the encryption/decryption to take place in SQL, you can use something like this pseudocode: SELECT name, dob, DECRYPT(ssn) as rawssn FROM deadbeats HAVING rawssn LIKE '%393%'; You can assign an alias and use HAVING instead of WHERE. http://dev.mysql.com/doc/refman/5.0/en/select.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Subject: [PHP] eval and HEREDOC
Hello,
I am having trouble with a part of my templating script. I'll
try to explain:
The template itself is HTML with PHP code inside it, like:
div?=strtoupper($user['name']);?/div
And I have the following code as part of the templating engine:
$template = file_get_contents($file);
$template = return TEMPLATE\n.$template.\nTEMPLATE;\n;
$template = eval($template);
The problem is that the eval() HEREDOC combination gives the
following output:
?=strtoupper(Array['time']);?
If in the HTML file (template) I use
div?=strtoupper({$user['name']});?/div
I get ?=strtoupper(username);? as an output.
I have tried closing the php tag like this:
$template = return TEMPLATE\n?.$template.\nTEMPLATE;\n;
but the extra ? only gets outputed as HTML.
This is my first post to this mailing list, so I great you
all and thank you for any kind of solution to my problem.
Why are you using HEREDOC to begin with? I personally find them to be ugly
and more trouble than they're worth.
You can write the same thing as this I think (untested):
$template = eval(file_get_contents($file));
But you might also consider using include_once or require_once instead
of this eval() business.
Also note, that a string can span more than one line and have variables in
it. It can even be used with code, so HEREDOC is again useless for most
situations:
$foo =
Hello $name,\n
\n
Today is .date('Y-m-d').\n
\n

Nulla eros purus, pharetra a blandit non, pellentesque et leo. In augue

RE: [PHP] Serial Numbers
-Original Message- From: Gary [mailto:gp...@paulgdesigns.com] Sent: Monday, July 12, 2010 11:53 AM I'm sure it is possible, but I am unsure how to do this. I have created a Sale coupon that I was going to put up on a site that I manage, for visitors to print out and bring to the store. The coupon is currently a .png, however I was planning on converting to a pdf. I would like to put on the coupon a serial number that increases by 1 everytime the page is viewed. I dont really care if someone refreshes the page and skews the numbers. Is this possible and could someone give me some help? Is there a reason you need to increment by 1? I mean, are you going to validate the coupon someone brings in to see if it's in the database or is used already? Since you say you don't care if the number is skewed, it sounds as if you don't care about the code either really. Point being, why not just use md5(time()) or uniqid() or something and make some truly unique code (that you may or may not wish to store in a DB). This will be obscure enough the average person won't know that it isn't tracked and most likely won't try to make their own. If I saw 123457, I'm pretty sure I could make a coupon with 123500 on it. But if I saw 6ccd780c-baba-1026-9564-0040f4311e29 then I'm not really going to try and fudge one of those. Then I'd use the barcode library to print the code (again, doesn't have to actually work if you're not going to do a lookup) just to add more realizm to it. There are a billion different ways to make a unique ID. Even IF you are going to track them, you really shouldn't do a sequential code as you originally wanted to do. http://us.php.net/manual/en/function.uniqid.php http://php.net/manual/en/function.com-create-guid.php http://us.php.net/manual/en/function.mssql-guid-string.php http://us.php.net/manual/en/function.md5.php http://us.php.net/manual/en/function.sha1.php http://us.php.net/manual/en/function.hash.php http://us.php.net/manual/en/function.time.php http://dev.mysql.com/doc/refman/5.0/en/miscellaneous-functions.html#functio n_uuid Heck, you could even just use ip2long() on their IP address and then when someone redeems the coupon code, a simple long2ip() would tell you if it's a valid IP format rather than some hacked up string. http://us.php.net/manual/en/function.ip2long.php http://us.php.net/manual/en/function.long2ip.php Daevid. http://daevid.com Some people, when confronted with a problem, think 'I know, I'll use XML.'

Have you looked at the memory settings in php.ini?
I doubt that is the cause, at least not by itself. 21504
characters is
only 21K of data (could be more if the characters are multi-byte
encoded, but still less than 100K) , and the default
memory limit in
PHP is 128M. I'm not sure what else it could be, though,
as I don't
see any limitations on file_get_contents() discussed in
the manual.
Default memory limit is still 32MB on every default install
I've seen.
The manual currently shows 128M, and that's what I've seen for some
time now. Even so, a function returning less than 100K shouldn't
exhaust 32M of memory either, unless something else is at play. If
there is a memory limit being reached, PHP should log either an error
or warning (I can't remember which).
Maybe try to specify the number of $maxlen bytes to read?
http://us4.php.net/file_get_contents
string file_get_contents ( string $filename [, bool $use_include_path =
false [, resource $context [, int $offset = -1 [, int $maxlen = -1
)
You could also do it the faster and old fashioned way:
$fh = fopen('/tmp/test.zip', 'r');
$data = fread($fh, filesize('/tmp/test.zip'));
fclose($fh);
Or if it's multibyte maybe try this:
function file_get_contents_utf8($fn) {
$content = file_get_contents($fn);
return mb_convert_encoding($content, 'UTF-8',
mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true));
}
