Re: [PHP] COM - Assigning to method.
Hi Andrew
Thanks for this.
But I'm still getting errors. I think I need to explain a bit more.
Unfortunately there isn't a PHP API for this application I'm trying to
interact with, my goal really is to be able to expose the COM
functionality over a web-service such as SOAP so I can use it in a
CMS. The application I'm trying to integrate with is Blackbuad's
Raiser's Edge - API documentation here:
https://www.blackbaud.com/files/support/guides/re7ent/api.pdf
I think part of the problem is that the field names are also
represented by an integer. So to get data out I would do:
$oBank-Fields(22); // which maps to BANK_fld_BRANCH_NAME.
When I do:
$oBank-22 = 'blah blah';
I get an error because a property can't be numeric, it has to start as
alpha character. If I use:
$oBank-BANK_fld_BRANCH_NAME = 'blah blah blah';
I get the following error:
Fatal error: Uncaught exception 'com_exception' with message 'Unable
to lookup `BANK_fld_BRANCH_NAME': Unknown name.
I've also tried using your Value property returned by Fields():
$oBank-Fields(22)-Value = 'Blah Blah blah blah';
Which I then get:
PHP Warning: Creating default object from empty value in [C:\Users]
Fatal error: Call to undefined method variant::Save()
Soo seems nearly impossible to implement a safe way to write to the COM API.
At the moment, I'm still in the scoping/prototype stage of my project,
so I'm beginning to think that using this COM API for this project is
a no-go, which is unfortunate. I'm also guessing even if we did
implement this API, exposing it as a Web Service is going to be tricky
for performance sake (given that I've read that COM doesn't
multithread very well??)
Many Thanks
Adam.

$API-SignOutOnTerminate = True;
$Record = new COM(Data.Record);
$Record-Init($API-SessionContext);

I've also tried (below) but the API says wrong number of parameters
$Record-Fields('BANK_fld_ACCOUNT_NAME', 'Test Account');
I've also tried something crazy like this (below) but that overwrites
the $Record object.
$_R = $Record-Fields('BANK_fld_ACCOUNT_NAME');
$_R = 'Test Account';

That example isn't assigning values to method return value. Fields is a
collection of ADO Field objects. The default property of a Field object is
its Value property, so the shorthand is simply assigning the values of the
variables to the value of each field in a record within a Recordset.
Andrew
So ..
$oBank-BANK_fld_ACCOUNT_NAME = Test account;
sort of thing.

Richard has the general idea correct, but as I recall it is a little
more involved because it's COM. I've never done that much with COM in
PHP because it was always such a pain. The example you posted probably
used to require com_set() in PHP 4, although it looks like that has
been deprecated in favor of a more typical OO syntax in PHP 5. Is

Re: [PHP] Load testing an app
On Mon, Apr 22, 2013 at 10:41 PM, Andrew Ballard aball...@gmail.com wrote:
The other developer in our office spent some time profiling the site with
xdebug and found that an exec() call to netsh used on a couple pages seems
to take 2-4 seconds to complete. Unfortunately, those exec() calls are the
one function that we cannot test in our development environment. We are
considering some optimizations, but since load on the production server is
at a seasonal low we want to duplicate the problem so we can measure the
impact of any changes we make. We spent most of today hammering the site
with JMeter today in an attempt to reproduce the issue. While we were
easily able to slow the site to a crawl (some samples taking over 2 minutes
to complete), the server returned to normal as soon as the test concluded
and it never became totally unresponsive like it did this past fall.
If you can't test the exec calls, directly, I'd refactor the functionality
that calls exec() so you could pass in replacement functionality that
creates that artificially creates the pause in your development environment:
function callnetsh($args, $func) {
$func($args);
}
// in dev environment, pass in $func that doesn't call exec but just sleeps
for the expected duration
callnetsh(['some', 'args'], function($args){
sleep(4);
});
We're both new to JMeter. I know a single test server may not be able to
create enough simultaneous requests to accurately simulate real traffic,
but I'm fairly confident that our tests involved far more (roughly-)
simultaneous connections than we were experiencing live. (The first test
used 20 threads; we gradually increased the threads for each test to 500
threads before we quit for the day.) The site is on a private subnet, so
distributed and/or cloud-based testing are probably not options.
2 quick notes:
If you have a linux box available, I like the simplicity of siege, but
jmeter is nice, too:
http://www.joedog.org/siege-home/
If the exec() calls were not being executed (e.g., they were bypassed) and
weren't being accounted for in terms of processing time, then these tests
would likely fail to recreate the load issues with similar numbers.
The site is running PHP 5.3 on IIS/Windows Server 2003. The netsh calls are
to a DHCP server on a separate Windows server, and the database is SQL
Server 2008 (previously 2000).
PHP 5.4 offers performance improvements. I don't suspect the migration from
SQL Server 2003 to 2008 caused any of these issues.
So, any ideas we can try?
We'd probably have to know more about what the netsh calls were doing.

A 301 as a response to PUT just means the server relocated/renamed the resource. - the other provider does respond as expected (though I agree, that is the weakest argument: expectations != specifications ) Nobody, nowhere, matches the spec. - the provider does allow sync'ing Sunbird, iCal, ... over CalDAV, and that works, even entering a new event (which is a PUT action).

[PHP] Close enough to Friday...
Just wanted to toss this out as something I quick developed in case it could help others: https://github.com/AdamJonR/PreHP Essentially, I just wanted a quick pre-processor that would work with PHP so I could limit some of the processing done at runtime. As opposed to C macros, I wanted to design it so that files could/should be developed to be valid html/php without the preprocessor. The preprocessor merely speeds the performance. The example for templating could be redone to use includes and then replace those with the inlined content, I just prefer to work with skeleton HTML so I can validate the XHTML as I go within the static file rather than having to check the content on a test server. The preprocessor is dumb (for now, I'm not parsing the PHP to ensure the comments are not contained within strings, etc.), but this shouldn't pose an issue for most situations. Anyways, I just whipped this up so I could ditch Dreamweaver Templates (which I used so the templating happened prior to runtime, too), as I'm trying to save some money and I don't want to upgrade to the next version :) Happy Friday!

Now, as to preprocessing: how does this benchmark out? Have you

Well, it depends...
For example, if you use code similar to the inlined function example,
there is a difference. In that example, the inlined code runs almost
twice as fast.
?php
$a = 1;
$b = 2;
$start = microtime();
for ($i = 0; $i 1; $i++) {
$result = ($a $b $a % 2 !== 0) ? $a : (($b % 2 !== 0) ? $b : (($a

}
$runtime = microtime() - $start;
echo $runtime;

?php
function maxodd($a, $b)
{
return ($a $b $a % 2 !== 0) ? $a : (($b % 2 !== 0) ? $b : (($a %
2 !== 0) ? $a : null));
}
$a = 1;
$b = 2;
$start = microtime();
for ($i = 0; $i 1; $i++) {
$result = maxodd($a, $b);
}
$runtime = microtime() - $start;
echo $runtime;
?
That said, there's tremendous variance across the possible range of
function types (e.g., number of args, complexity of function, etc.),
so there's no guarantee you'll always see a worthwhile (which is also
subjective) improvement. I'm going to use inlining for functions that
output html-escaped output (the function wraps htmlspecialchars to
allow whitelisting), as they're frequent and simple, the very type of
function that is easily inlined and provides some speed benefit.
In terms of the templating, in my tests using siege comparing
Dreamweaver Templates vs PHP includes, I've typically seen significant
benefits when the template requires multiple includes, with the effect
dropping off as the number of includes approaches 0. These results
should be the same. Again, there seems to be a broad range of
considerations (in terms of using APC, using absolute paths helped the
include performance:
http://www.php.net/manual/en/apc.configuration.php#ini.apc.stat)
There are usually bigger ways to enhance performance (data
persistence, etc.), but in the same way that I try to teach my little
girls to turn off the faucet in between spitting into the sink even
though monitoring showers can do much more to save water, when I see
simple ways I can consistently save cycles, I try to implement them :)

It's possible that the prod servers (those making the call to fopen) aren't configured to allow the http wrapper.

Well, array_flip has it's own potential issues (duplicate values are
lost, so my example of using zeros would not work.) I suppose I could
duplicate the keys as the values (e.g., array('value 1' = 'value 1',
'value 2' = 'value 2', ...).) Then, the keys would allow me to
utilize the nice properties of hash maps whilst maintaining the
ability to work with the values as one normally does in typical array
functions.
Ex:
$a1 = array('apples' = 'apples', 'oranges' = 'oranges', 'pears' = 'pears');
$a2 = array('oranges' = 'oranges', 'kiwi' = 'kiwi');
// can use the union operator without any additional calls and the
performance is stellar
$a3 = $a1 + $a2
// can use the values of the array using the convention that the value
is what you expect to handle/manipulate
foreach ($a3 as $val) {
echo $val
}
Here, the clunkiness is the redundancy in the array, but, as Claude
Shannon has demonstrated, redundancy isn't all bad :)

In PHP the array is in fact a hash map, but especially it is _used_ for

operator or built-in function, that merges two arrays _and_ treat them as
set (instead of the hashmap, what they are). Your solution is the way to go.
Sure, I know about the underlying implementation. I was just hopeful
because several of the array functions handle the maps differently
depending on whether the keys are numeric or string or both.
If I wanted to get cute, I could store the value in the key (e.g.,
array('value 1' = 0, 'value 2' = 0, ...)), and that allows me to use
the '+' operator. In spite of the nice performance benefits of this
approach (leveraging the hashes benefits), the code that utilizes the
arrays becomes quite clunky.

First of all, I believe PHP is smart enough to not generate bytecode

fact that you can write a function with errors, which will run fine

I believe this is untrue. PHP generates the bytecode and then parses
the bytecode per request to generate the userland infrastructure,
including classes and functions, for the entire include file. During
the generation of bytecode, PHP doesn't know apriori which functions
will be called at runtime. I suspect if you asked for confirmation of
this on the internals list, they'd confirm this. In terms of errors,
there are certainly different stages that errors can occur, and what
you're referring to are runtime errors. Runtime errors don't
necessarily show up in every possible execution branch. That doesn't
mean that PHP didn't generate the code for the userland functionality.
The speed difference between loading 5K file or 50K file (assuming
continuous blocks) is extremely small. If you split this library, you
would have PHP files that require you to load maybe 3 or 4 different
files to have all their functions.
Here's where I believe we have a communication issue. I never spoke of
splitting up the library into 3 or 4, or any number of different
files. The opening post states that only 10% of the pages need the
library. I suggested that he only include the library in the 10% of
the pages that need the library. That said, it's possible I
misinterpreted him.
I will say that I do disagree with your analysis that difference
between loading a 5K or 50K php file is extremely small. So I just put
this to the test.
I created a 5K file and a 50K file, both of which have the form:
function hello1(){
echo hello again;
}
function hello2(){
echo hello again;
}
etc.
I have XDegub installed, have APC running, warmed the caches, and then
test a few times. There results all hover around the following:
Including the 5K requires around 50 microseconds. Including the 50K
requires around 180 microseconds. The point is that there is a
significant difference due to the work PHP has to do behind the
scenes, even when functions (or classes, etc. are unused.) And,
relevant to the dialog for this current thread, avoiding including an
unused 50K PHP on 90% of the pages (the pages that don't need the
library) will lead to a real difference.

The point is, there is a real difference. The question remains if the difference is enough to act on in future code bases (and I would say yes if my tests showed this difference, you may say no.) In functions with more lines (say ~100 lines per function), you'll see a different ratio between 5k and 50k. In my tests it is: - 5K: 22ms - 50K: 34 ms Those trends/results depend significantly on the contents of the functions, too. The overly simplistic example we've used both helps and hurts the analysis (I'll admit my example likely has more functions than other 5K/50K files, and I suspect most functions require more complicated work behind the scenes to build up than echo statements.) The point I'd make here is that it's very difficult to have apriori knowledge of how something will perform without testing it.

more code, it's hard to tell what this means for your particular
example.
Do the scripts that do not contain these lines run without it or is it
included automatically every time the database is accessed regardless of
which script is accessing it?
If not how do I deal with it?

Hard to know from your example. There are some great resources
covering general PHP security practices that can help you get up to
speed a bit. Here's an oldie but goodie that might help shed some
light on some of the code you're seeing:

What I was not expecting was a string of 'Notices:' complaining about the

and make sure it's disabled again on PHP5.4?
Having spent several months getting the code clean on E_STRICT, switching it
off again will really pig me off, but I can't see any real alternative given
the number of languages and strings that will need reworking simply to get
things clean :(
Well, I'd do the following to avoid issues in the future.
1) Create a function like that below, which provides global access to
variables and allows you to update existing values:
function val($name, $value = null)
{
static $values = array();
if ($value === null) {
return isset($values[$name]) ? $values[$name] : null;
} else {
return $values[$name];
}
}
2) Create a php script that searches out define(SOME_NAME_PATTERN,
value) and replaces that with val(some_name_pattern, value).
3) Create a php script that searches out SOME_NAME_PATTERN and
replaces with val(SOME_NAME_PATTERN);
Not too bad in terms of work, as PHP's parsing capabilities are really nice.
Hope this gives you ideas :)

Re: [PHP] Is PHP unsuitable for HTML5 WebSockets?
I have read in some places on the net that PHP is not suitable for WebSockets due to it's nature. That WebSockets are designed for long running threads/processes which each maintain multiple event-driven connections, whereas PHP was designed around the short-lived single process procedural paradigm. Well, you could certainly run into trouble if you're not careful. For example, using an Apache module PHP installation would not likely end nicely :) Yet on the other hand I see lots of guides and libraries (such as http://socketo.me/) on the net that deal with PHP WebSockets. So I don't know what to think at this stage. Is PHP a suitable platform for developing a web application that requires WebSockets? I'm sure you could get get your application running with PHP. That said, I personally would not use PHP for the web socket implementation in my stack. I'd probably use Go, node.js or even Erlang for the web socket server itself (non-blocking IO is baked into these environments, which is handy for limiting the resources required for this type of application), but I'd likely use PHP for components that weren't directly tied to the web sockets (db frontend, etc.) Obviously, that's just my personal preference, and as you've noted, people are doing nice things in the web sockets world with PHP, so it can be done. That said, I suspect I'd have an easier time with one of the other languages for this particular aspect of an application, as the resource management should be much easier to manage. I don't think there's a right tool for the job, but I do believe some language environments may better facilitate this specific type of development. Have fun!

But what is the best way to invoke an action? I can't do it with the baseController constructor, becouse parent class can't see inherited classes. And I can't do it with the constructor of the inherited class, becouse this way I would overwrite the parent constructor.

All this works good, but, we need, in the delete function to delete from

mysql_select_db(vsq,$connmy);
mysql_query(DELETE from userprefs where

$mysql_close($connmy); this fails, unless we use a mysql_close prior to it,
and then reconnect to original database after we run this delete, how can we
get around this without closing and reopening?
We have a perl script doing similar for manual runs, and it works well
knowing that $connmy is not $connect, I'm sure there is a simple way to tell
php but I'm darned if I can see it.

Just create a new resource/connection to MySQL and pass the identifier into
mysql_query().
You'll also want to use mysql_real_escape_string() by the looks of it to
attempt to stop SQL injection.
Something like this will do it:
$db1 = mysql_connect($host,$user,$pass);
$db2 = mysql_connect($host,$user,$pass);
mysql_select_db('db1',$db1);
mysql_select_db('db2',$db2);
// do your queries with $DB1
$result = mysql_query(delete from userprefs where
clientr=.mysql_real_escape_string($user,$db1)., $db1);
// do your queries again with $DB1
mysql_close($db1);//close db1
mysql_close($db2);//close db2

Hi,
So, you:
1) Visit page a.php (I'm assuming without the flag)
2) Are forwarded to page b.php, which you're expecting to store a
session variable 'test'.
3) Then forwarded back to page a.php.
You're likely expecting that you're return visit to page a.php should
reveal the 'test' variable.
The issue is that you're calling session_commit(), which is actually
an alias for session_write_close(). This function actually stops the
current session. So, when you hit the line $_SESSION['test'] = 'test',
your session has already terminated.
Try removing the session_commit() calls (or at least permanently
remove the first call.) You only want to call session_commit() when
you're done accessing/updating $_SESSION variables.

jslint.com verifies this as good JSON (although I thought there had to be

Speaking to your belief that arrays had to have square brackets,
json_encode examines the PHP array and only encodes sequential numbers
JSON arrays. Others (as in your case) are encoded as object literals:
http://php.net/manual/en/function.json-encode.php
That said, you can still access Javascript Object properties with
array access if you prefer in the client code:
http://www.quirksmode.org/js/associative.html
If you were me would you just generate the JSON? If not what is he best way
to output an array that will nest properly for each subsequent query?
Because of the options json_encode provides and the flexibility it
affords while in PHP, I would generate PHP and then always use
json_encode to generate the JSON as needed.

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

[PHP] Race Condition In PHP Session Handler
php-5.3.3-3.el6_2.6.x86_64 2.6.32-220.4.2.el6.x86_64 After some testing we moved our production PHP intranet site from an old server to a new CentOS 6.2 instance running the mentioned versions.

[1] Not quite true - a Pascal compiler I once had to use in 1983 lacked a return statement, so I had to fake it by putting a 999: label at the end of the function and goto-ing to that. Goto has it's uses, demonizing it due to the poor implementation and misuse of it's same-named historical counterparts is an exercise in closed-mindedness. Goto can really shine in parsers and various other scenarios. While the example shown may be contrived it doesn't miss the point. Since goto cannot jump out of the function nor jump into the function it is well constrained to provide readability while eliminating complexity. Additionally, it is quite likely that it is more optimal. A single jump target versus one or more state variables to control nested conditionals or loops results in faster execution (also important for parsers). I've had a strong opinion on goto for a very long time. I was one of the proponents who argued on internals for its inclusion several years ago. I stand by its utility and refer the reader to the fact that many open source projects, especially ones that use some kind of parser, have goto hidden within their implementation. You can find it in the C code for the PHP, MySQL, and Apache to name a few easily recognizable projects. Cheers, Rob. All excellent points, Robert. Tim mentioned that my example was a straw-man, and you mentioned it was contrived. Actually, it's a refactoring of a real function in my web framework that I've committed to trunk and going to use for a while (it's functionally inspired, and having the ability to store and retrieve immutable values is quite handy in this situation.) I like experimenting with different approaches (my background is in cognitive psychology), and there's certainly research to show that deeply nested ifs are problematic, cognitively speaking. Then, there are the other techniques mentioned in the blog post to deal with them (guard clauses, pulling out functions, grouping conditions), but they have they're issues, too, in terms of processing (they can hurt proximity of related concepts, forcing programmers to work against the mental model they've built up of a problem, etc.) There are going to be issues with the goto approach I took to refactoring the function, too, but I'm keenly interested in playing around with it a while and letting the evidence accrue over time. I've read many, many sources that seem to reject ANY approach using GOTO even without properly evaluating its use within a language like PHP that offers some beneficial restrictions.

I remember being faced with spaghetti code 35 odd years ago - yes, horrible. But what do we mean by ''spaghetti code'' ? I remember code where every 3rd statement was some form of GOTO - yuck! One very desirable feature of code is that it be clear, ie: lucid, able to be understood by others. Too many GOTO statements and it is hard. However: a few GOTOs can make things clearer.

I guess what I meant was, that I'd never have written it that way in the
first place, so as an example it felt contrived. Amateurs or people with no
training (in particular physicists at CERN 40 years ago) should be kept
well clear of the goto. I'd probably write your function like this:
function val_nested ($name = null, $value = null, $is_mutable = false)
{
static $values = array();
static $mutables = array();
if ($name===null) return $values;
if ($value===null) return isset($values[$name]) ? $values[$name] :
null;
if (isset($values[$name]))
{
if (!$val_is_mutable = in_array($name, $mutables))// Set
existing value
{
$msg = 'The value ' . $name . ' is immutable and has
already been set to ' . $values[$name] . '.';
throw new Exception ($msg);
}
return $values[$name] = $value;
}
if ($is_mutable) $mutables[] = $name; // Set new
value
$values[$name] = $value;
return $value;
}
I always add blank lines for clarity. Remove those and the above is 30%
shorter than yours - as far as I could tell, none of the else clauses was
required.
My approach is:
1) deal with the trivial and error cases first
2) deal with the real work next

Thanks for providing your example, Tim. Bailing early through guard clauses
towards the top of the function body is a nice approach (I used it in my
second example, but I also used conditional grouping and factoring out
functions so I could display all three techniques listed in the post.)
I might try performing some experiments using the different versions of the
code and test for things like:
- Time it takes to add some additional piece of functionality to the code.
- Number of bugs in the revision.
- Time it takes for one to write a new function using only one of the
possible techniques (deep nesting, guard clauses, pulling out functions,
goto, etc.)
- Providing function input and testing accuracy of predicted output
Thanks for the time you've taken to provide your PHP coding preference in
this situation.

I should have used basename() in my question. The main point I was trying to get was which one is more secure and not subject to cross-site scripting or other such security issues? IOW, if you had to bet your life on it, which would be most secure in reporting an accurate basename()? That's an interesting question. Because $_SERVER['SCRIPT_NAME'] doesn't include path info appended to the get request, it greatly limits the attack surface, so I try to use it when I can. However, there are times when you want the ability to pass in additional path info (e.g., pretty urls), and that makes $_SERVER['PHP_SELF'] quite useful. In terms of securely using $_SERVER['PHP_SELF'], the one thing I don't ever recommend is trying to sanitize input (this view is in stark contrast to some of the resources online that detail how to safely use $_SERVER['PHP_SELF'] through a combination of techniques including sanitization.) I suggest that any time script receives that doesn't meet its expectations, the script should throw away the data and kindly communicate to the user that they'll have to try the request again with valid data. To use $_SERVER['PHP_SELF'] safely, the most important thing is context. In order for an XSS attack to succeed, it has to sneak in data that is structurally meaningful in the context of its use. If the web page outputs $_SERVER['PHP_SELF'] in an href such as the one below, then a double quote (or any of its possible encodings which buggily sneak through older browsers, but modern browsers seem to have corrected many of these issues) must be escaped: // if a double quote comes through PHP_SELF here and is not escaped, we're in trouble // https://www.owasp.org/index.php/XSS_(Cross_Site_Scripting)_Prevention_Cheat_Sheet#RULE_.232_-_Attribute_Escape_Before_Inserting_Untrusted_Data_into_HTML_Common_Attributes a href=?php echo $_SERVER['PHP_SELF']; ?Link back to this page/a So, in the above case, I would first filter the PHP_SELF value through a regex that establishes a whitelist of valid values and/or characters (if you know all the possible paths of your app ahead of time, make sure there's a match; if you know that the path info only includes letters a-z, make sure there are they are the only characters you allow; etc.), and then for valid input, escape the output using htmlspeciachars(). NOTE: Developers who fail don't use quotes on attributes would have to be much more careful and escape several other characters in the above example. That all said, if PHP_SELF was being echoed out into a script tag, the above technique would be insufficient to protect against XSS, as the content of the script tag has many more structurally meaningful characters that have to be watched for and escaped. So, it really varies by the context of use. I'd use SCRIPT_NAME where I don't need the path info (but I'd still likely whitelist it's possible values and escape it's output.) And, if I needed the path info, I'd whitelist the possible PHP_SELF values and then escape the output according to the context. That all said, if my life depended on security of the app, I'd probably be very slow to put up any web pages, as the amount of testing and auditing I'd want to perform would be on the scale of years ;) Adam -- Nephtali: A simple, flexible, fast, and security-focused PHP framework http://nephtaliproject.com

[PHP] php://input
Hi,
I am trying to read variables from input method.
I am using this tuorial:
http://www.lornajane.net/posts/2008/Accessing-Incoming-PUT-Data-from-PHP.
Here is my code:
?php
if($_SERVER['REQUEST_METHOD'] == 'GET') {
echo this is a get request\n;
echo $_GET['fruit']. is the fruit\n;
echo I want .$_GET['quantity']. of them\n\n;
} elseif($_SERVER['REQUEST_METHOD'] == 'PUT') {
echo this is a put request\n;
parse_str(file_get_contents(php://input),$post_vars);
echo $post_vars['fruit']. is the fruit\n;
echo I want .$post_vars['quantity']. of them\n\n;
}
?
I am using the firefox extension poster to run this example. GET
works fine but when using PUT, file_get_contents(php://input)
returns an empty string.
I found a bug related to this: https://bugs.php.net/bug.php?id=51592
I am using xampp on win7 (
+ Apache 2.2.17
+ MySQL 5.5.8 (Community Server)

Use a templating language - yes, I understand that is what php is for - but I won't go into it. You should not be echoing, printing, or any other method of concatenating html dealing with escaping quotes inside your php logic code. Please separate your concerns. Not sure what that means? That's OK! If you want to move forward, look up how modern frameworks deal with this issue using their views or template views. You don't have to use a framework if you do not want to, that's perfectly fine. If it works, it works. But in the end, it the separation of logic and html is essential to code maintenance. Eric, There are many posters to this list, and there exists a broad range of programming styles and abilities. I'll bet you're a competent programmer, and that you've worked hard to hone your craft. It takes passion and drive to improve one's skill set. However, I'd encourage you to focus that passion on the list in a way that facilitates the growth of those with questions whilst staying true to their current, specific needs. Frankly, every answer on the list could begin with the suggestion that they just use a framework. The list is here to help build up the entire skill set of PHP developers. Let's reexamine the original post: Hello all. Can someone tell me which of the following is preferred and why? Use of the word Which implies that there were a closed set of options they wanted to consider, although we did offer some others, but they all stayed relatively true to his original options. echo a style='text-align:left;size:**14;font-weight:bold' href='/mypage.php/$page_id'$**page_name/abr; echo a style='text-align:left;size:**14;font-weight:bold' href='/mypage.php/.$page_id.**'.$page_name./abr; Simple. Please note there is no logic anywhere in this example. PHP is truly serving merely as a templating language here. So, while I agree with the general notion that logic should not be intermingled with markup, this particular example does not serve as the anti-pattern you suggest. Also, note that we aren't sure where the $page_id and $page_name variables are coming from. In instances where these are set manually within the script (like a view variables at the top of the page), there's no need to escape anything. That said, you're right, if the data is coming from somewhere else, escaping should happen, but there's not enough information to infer that, as you say, You should not be echoing, printing, or any other method of concatenating html dealing with escaping quotes inside your php logic code. When I come across the above code in line 1, I have been changing it to what you see in line 2 for no other reason than it delineates out better in BBEdit. Is this just a preference choice or is one method better than the other? The above statement suggests there's an existing codebase that was being worked through. In this light, the answers mostly focused on answering the OP's original question, realizing that this was existing code that he was refactoring lightly as he goes. This is not to say that I disagree with all that you said, as I actually developed my own framework that: - Cleanly separates PHP from HTML to avoid the intermingling of logic and presenation: http://nephtaliproject.com/documentation/markup/ - Automatically handles output escaping, input validation: http://nephtaliproject.com/documentation/examples/contact.php - And lots of other features that coincide with the general focus of your words. Given that work, I think it's fair to say that I do agree with several of your general points for web development overall. However, this question wasn't a big picture question on how to do web development with PHP. It was a simple question that was answered in a helpful, specific manner by several on the list.

Ah, I see, you're right. I thought he was using CBC (which I would

That also means that example #1 is wrong at mcrypt_encrypt help page[1].

[1] http://php.net/manual/en/function.mcrypt-encrypt.php#example-884
Nice catch in the documentation, Matijn. While it will encrypt and decrypt
successfully, the IV isn't being used, so it would seem to be a better
illustration of use of someone switched the mode to one that's using the IV.
Someone with access to the documents want to make the change to one of the
other modes (as Matijn pointed out, CBC is pretty common?)

Re: [PHP] Sequential access of XML nodes.
On Mon, Sep 26, 2011 at 12:24 PM, Richard Quadling rquadl...@gmail.comwrote:
Hi.
I've got a project which will be needing to iterate some very large
XML files (around 250 files ranging in size from around 50MB to
several hundred MB - 2 of them are in excess of 500MB).
The XML files have a root node and then a collection of products. In
total, in all the files, there are going to be several million product
details. Each XML feed will have a different structure as it relates
to a different source of data.
I plan to have an abstract reader class with the concrete classes
being extensions of this, each covering the specifics of the format
being received and has the ability to return a standardised view of
the data for importing into mysql and eventually MongoDB.
I want to use an XML iterator so that I can say something along the lines
of ...
1 - Instantiate the XML iterator with the XML's URL.
2 - Iterate the XML getting back one node at a time without keeping
all the nodes in memory.
e.g.
?php
$o_XML = new SomeExtendedXMLReader('http://www.site.com/data.xml');
foreach($o_XML as $o_Product) {
// Process product.
}
Add to this that some of the xml feeds come .gz, I want to be able to
stream the XML out of the .gz file without having to extract the
entire file first.
I've not got access to the XML feeds yet (they are coming from the
various affiliate networks around, and I'm a remote user so need to
get credentials and the like).
If you have any pointers on the capabilities of the various XML reader
classes, based upon this scenario, then I'd be very grateful.
In this instance, the memory limitation is important. The current code
is string based and whilst it works, you can imagine the complexity of
it.
The structure of each product internally will be different, but I will
be happy to get back a nested array or an XML fragment, as long as the
iterator is only holding onto 1 array/fragment at a time and not
caching the massive number of products per file.
Thanks.
Richard.

file_put_contents() doesn't throw exceptions. As the note on the exception
documentation says: Internal PHP functions mainly use Error reporting, only
modern Object oriented extensions use exceptions.
If you look at the documentation for its return value (
http://php.net/file_put_contents), you'll see that false is returned on
failure.
In this case, a warning makes more sense than throwing an exception anyway.
A warning can be ignored, either by changing the error_reporting level or
using the error control operator, whereas an exception must be dealt with or
execution halts.

Re: [PHP] How to sum monetary variables
2011/7/18 Martín Marqués martin.marq...@gmail.com I'm building a table (which is a report that has to be printed) with a bunch of items (up to 300 in some cases) that have unitary price (stored in a numeric(9,2) field), how many there are, and the total price for each item. At the end of the table there is a total of all the items. The app is running on PHP and PostgreSQL is the backend. The question is, how do I get the total of everything? Running it on PHP gives one value, doing a sum() on the backend gives another, and I'm starting to notice that even using python as a calculator gives me errors (big ones). Right now I'm doing the maths by hand to find out who has the biggest error, or if any is 100% accurate. Any ideas? Hi, I've not had issues with PostgreSQL when using the numeric data type.

I'll try it on my PHP 5.3 web framework later today. Thanks for working on this project! Adam 2011/6/29 Ondřej Nešpor kon...@andrewsville.cz Hi everybody! We'd like to introduce you our documentation generator - ApiGen 2. We use it as a replacement for PhpDocumentor (that is not being developed for more than 3 years). You can find it on Github https://github.com/apigen/** apigen https://github.com/apigen/apigen along with a comprehensive readme (describing its features and command line options). Compared to PhpDocumentor, ApiGen si significantly faster and more flexible. Currently we are preparing PHP 5.4 support (mainly traits). An interesting feature is that it describes the source using reflection, however not the PHP's reflection as you know it. We have developed our own library that emulates reflection using the tokenized source code. This library may be useful everywhere you need to process the PHP source code and don't want to include/require it.

[PHP] Php filter validate url
Hi, I wanted tu use php filters for validation to avoid regular expresions. Is it possible that FILTER_VALIDATE_URL only checks if the string has http:// and do not check for the format domain.something? $url = 'http://wwwtestcom'; $url = filter_var($url,FILTER_VALIDATE_URL); echo $url; - Or I am doing something wrong Thank you -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] newbie date time question
$dt is an object as the error says, so you cant echo it, becouse its not a string (it can be with __toString magic method, or use print_r/var_dump to output your object). Try the format ( http://www.php.net/manual/en/datetime.format.php) method on your $dt object.
