Daevid:

Go ahead and strip out the whitespace, but replace it with a delimiter string 
that is unique and then don't consider that delimiter when comparing strings to 
strings.

Afterwards, if you want to keep the string (instead of deleting it), then 
reverse the process adding back in the whitespace and removing the delimiter.

Also, you may want to look into using array_unique() for comparing groupings of 
several strings (i.e., paragraphs) to other groupings. It works pretty slick 
for me.

Yes written from scratch years ago.

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.

[shiplu]

Is your ticketing system written from scratch? Because such type of logic
is already implemented in existing help desk softwares.

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.

[PHP] How do I remove a string from another string in a fuzzy way?

[Daevid Vincent]

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.

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 "\nsearching for
entry_message[$j] in [i = $i]:\n$output_message\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.

Ah, yes, good point -- as written, my code will raise two notices. In
addition, "declare" the $freq array:

$freq=array();

as well before the foreach loop to ensure notice-free operation.

foreach ($words as $word) {
  if (array_key_exists($word, $freq)) {
$freq[$word] = 1;

This is usually a first-year CS programming problem (word frequency
counts) complicated a little bit by needing to extract the text.
You've started off fine, stripping tags, converting to lower case,
you'll want to either convert or strip HTML entities as well, deciding
what you want to do with plurals and words like "you're", "Charlie's",
"it's", etc, also whether something like RFC822 is a word or not
(mixed letters and numbers).

When you've arranged all that, splitting on white space is trivial:

$words = preg_split('/[[:space:]]+/',$text);

and then you just run through the words building an associative array
by incrementing the count of each word as the key to the array:

foreach ($words as $word) {
$freq[$word]++;
}

For output, you may want to sort the array:

ksort($freq);

Good stuff, but the idea that you need an official test person or a test team 
to produce solid code that minimises runtime errors is, in my opinion, 
completely the wrong attitude. I've been in similar situations several times 
and have found that the key is not to try and solve the problem in one big 
push. The key to solving the problem of a large codebase with minimal testing 
is simply to start somewhere.

Put in the infrastructure for unit testing, then make writing tests a part of 
your standard development process. Over time you will find that you are unit 
testing the majority of the code. Yes, that will make things take longer, but 
you can also be confident that when you fix a bug it stays fixed, because you 
know there's a unit test that verifies that the bug has not returned.

In my experience and opinion, limited resources is a big reason to implement 
some level of unit testing as soon as humanly possible, not a reason why you 
can't. Once you have the unit testing infrastructure in place, make running the 
tests the first step in your deployment process. You mention you now use a 
version control system, consider adding a hook to require that the unit tests 
pass before allowing code to be committed. Alternatively implement a CI 
environment which publicly ridicules anyone who checks in code which breaks the 
unit tests - it's amazing how much of a motivator this can be, even in a small 
team of seasoned professionals.

Not a secret. Not even close to being a secret. I'm no stranger to sites with 
the sort of traffic you have, and then some, and I'm fully aware that it 
presents a unique set of challenges, but there are simple steps you can take to 
make life easier.

Most of the specific issues you mention (DB connections, memcache weirdness, 
concurrency problems, and crawler activity) are the result of poor architecture 
and/or flawed server configuration. Where the architecture is poor I'd 
recommend you design a new architecture and find a way that you can start 
moving towards it, piece by piece, without having too much impact on your 
day-to-day activities. This is not always easy but I've done it several times 
and know it can be done in most situations.

There will always be issues that crop up that you couldn't possibly have known 
would happen, but you can load test your app to see what happens at levels of 
traffic an order of magnitude above that which you expect. One of my current 
clients has a test tool that can generate traffic levels that hit the limit of 
EC2 network throughput specifically to see what would happen if they had a 
sudden and dramatic increase in usage. Knowing the application can cope at 10x 
the expected level of traffic is the only way you can be sure that it can cope 
with 1x the expected traffic without breaking a sweat.

There will always be situations that you don't foresee, and conditions that are 
difficult to test, but saying that you "can't possibly test" for them is simply 
wrong.

Re: [PHP] How do I enable more useful PHP error logging?

[Simon Schick]

Hi, Daevid

What you could do to have it quick is to install the plugin xdebug.

Here you can (as described in the documentation linked here) enable to get
some extra information for a E_* message from php.
http://xdebug.org/docs/stack_trace

I would not do that on a live-system where you have 30k v/s without
changing the default configuration as there are several options that would
dramatically slow down the system.
But if you're configuring this properly I think you'll get the best
information without changing the php-code itself.

Have you looked at log4php? [1] It's a log4j (Java based) logging
facility port to PHP.  IIRC for log4j, you can do various logging from
FINEST, FINER, FINE, INFO, WARNING, ERROR (?), SEVERE levels within
the application.  You can adjust levels as needed at run time.  You
may want to have a wrapper that will do back trace and record the
requested URL.  The log4* facility does rolling file logging, DB,
e-mail, syslog, etc.  (I've used the log4j and log4net before.)  Very
handy and flexible, IMO.

HTH,

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.

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.

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. ;-)

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.

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.

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.

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

deploy it to a fraction of your infrastructure.

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! 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.

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

I tend to set up a custom error handler that throws exceptions
(set_error_handler()), then set up an exception handler
(set_exception_handler()) that logs the backtrace (or saves it to a db)
available using debug_backtrace().

[PHP] How do I enable more useful PHP error logging?

[Daevid Vincent]

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.

I may be wrong, but as I understand it those headers are for older WAP 
browsers, not modern mobile-based browsers which are HTML-capable. The best way 
I've found to detect mobile devices is to examine the user agent header. While 
it's not 100% reliable it's the best method available.

This is the function I've used in the past to detect mobile devices: 
https://gist.github.com/1124666. I haven't used it for a little while so there 
are probably new devices out there that it can't detect but it should give you 
a good starting point.

I'm working on a mobile site and from the various searches and reading (and

$_SERVER['HTTP_X_WAP_PROFILE'] and a fallback $_SERVER['HTTP_PROFILE']

However, when I hit a phpinfo(); page using both an Android MyTouch 3G (2.2)

Ah, I see. I don't believe you mentioned that in your original query.
In that case, your only option probably is eval - something like:

eval("\$log_level_int = {$log_level_string}");

or:

$log_level_int = eval("return {$log_level_string}");

Cheers!

You assume I'm using that busted-ass "parse_ini_file()" function. ;-)

See previous emails as to why that's a useless option for me.

I wrote a much better parser which I'll post in another email.

That's odd -- parse_ini_file() should definitely translate those constants!
It certainly works on my v5.2.5 installation.

[PHP] How do I convert the string "E_ALL & ~E_NOTICE" to the decimal equivalent 6135?

[Daevid Vincent]

We're trying to move all of our configuration files for our DEV/TEST/PROD
and various python scripts and such that all need the same DB connection
parameters and pathing information to a common and simple config.ini file
they all can share across languages.

One snag I ran into is this:

[dart]
relative_url= /dart2
absolute_path   = /home/www/dart2
log_level   = E_ALL & ~E_NOTICE

But when I read it in from the file, it's a string (of course)

$log_level_string = "E_ALL & ~E_NOTICE";
echo 'log level string = '.eval($log_level_string.';').'';

This gives me nothing!:

log level string =

Wheras this one gives the proper values:

echo 'log bit level = '.(E_ALL & ~E_NOTICE).'';

Output is:

log bit level = 6135

But that defeats the purpose of a config file.

Install/upgrade libgd and freetype2 individually, then rebuild PHP using
those libaries.

[PHP] How do I upgrade GD?

[PmI]

Hi, 

how do I upgrade GD? PHP still comes bundled with the three year old version
2.0.34, even though there have been lots of bugfixes in 2.0.35 and 2.0.36
(most importantly, 2.0.36 now actually supports unicode text, rather than
"any unicode text as long as it's only UCS-2", which means any unicode using
blocks introduced after 3.1 don't work).

Related to that, how would one update both GD and FreeType2?

[snip]

So I figured it out... I was using the wrong command to compile libtidy.  (I am 
not a *nix geek so I had no idea I was messing it up.)  To get it working, I 
followed the instructions I found here: 
http://www.php.net/manual/en/ref.tidy.php#64281

My setup is slightly different from the person who wrote the directions in that 
I am running OS X 10.6.2 and PHP 5.2.12.  However, the only difference between 
the instructions I followed and what I actually had to do is that the line to 
comment out for me was line 525 instead of 508.  (The actual line is: typedef 
unsigned long ulong;)

Thank you everyone for your help!

what does it matter that it runs slowly, run it once and be done with it?
alternatively use the php tidy extension and avoid the file system and shelling 
out altogether.

actually I'd imagine shelling out from a webserver process is the bottle neck 
and not saving/reading
from the file system.

lastly I don't suppose you've heard of /dev/shm ?

and, er, no, I don't have experience with php://memory but you might try

[PHP] how do I use php://memory?

[Mari Masuda]

Hello,

I have a function that uses tidy to attempt to clean up a bunch of crappy HTML 
that I inherited.  In order to use tidy, I write the crappy HTML to a temporary 
file on disk, run tidy, and extract and return the clean(er) HTML.  The program 
itself works fine but with all of the disk access, it runs quite slowly.  I saw 
on this page (http://www.php.net/manual/en/wrappers.php.php) that I could write 
to memory by using php://memory.  Unfortunately, I could not quite get it to 
work.  The problem is that in the below function, the code within the [[[if 
(file_exists($dirty_file_path))]]] does not get run if I change 
[[[$dirty_file_path]]] to "php://memory".  Has anyone ever successfully used 
php://memory before?  If so, what can I do to use it in my code?  Thank you.

What about sending the form via POST, but to a URL that includes some
sort of session in the URL the form is sent to, for example:



Then your server script can reproduce the search from saved parameters
stored under the sid value.

This way, you retain the ability to bookmark the search, and use as many
search parameters as you need, without worrying about going over the GET
data limit no matter what browser the user has.

True, but for search parameters, it's IMHO best to use GET rather than POST
so the page can be bookmarked.

This used to be a concern "back in the day" with 255 bytes.

Not so much anymore with most browsers supporting > 2000 characters:

Re-writing it to handle $_REQUEST doesn't seem to solve much as the user
would still need to know the form element names and the actual form would
be either POST/GET. GET is the problem I have now. POST is a whole other
problem of not being able to bookmark.

This is for an internal intranet site so I can't use an outside shrinker,
however I suspect the code to create my own shrinker isn't so difficult and
this is a pretty interesting idea. Given your above observation, perhaps
this *is* the solution to persue further...

It's for users like you that I keep saying to people that Javascript
shouldn't define functionality but enhance it. People will turn their
noses up at that attitude, but, like you said, some people get downright
nasty with the things they do online with their scripts.

I've not used that CSP thing you linked to before, it looks like it's
not for validating user input going *to* your server, but to sanitise
the downstream content from your server to the users browser. Validating
user input should prevent this as best as possible, as it shouldn't lead
to output from your script being used as part of an XSS attack. However,
the real worry is with ISP's that modify your pages before they are
output to the browser, as Canadian ISP Rogers has been found doing:

http://www.mattcutts.com/blog/confirmed-isp-modifies-google-home-page/

No PHP class will be able to prevent that, as the ISP is modifying the
content en route to its destination.

for things whereby
- the server needs to generate tons of HTML for a small(ish) dataset, or
- the client generates data (also to be translated to html) that the
server doesnt really need to know about (yet)

js can really take some stress off the server.


I also like to run any content that has user contributed data through a 
server side filter that enforces Content Security Policy -


http://www.clfsrpm.net/xss/

That filter makes sure the content sent to the browser does not include 
stuff that violates the defined CSP, and thus greatly reduces the risk 
of malicious content that input filtering missed from reaching the end user.


Furthermore, when it does catch a violation, it reports the violating to 
a log file notifying me of the problem.


The only way that works for content generated client side would be if 
the user was running a browser that is CSP aware, and right now, they 
just don't exist. Firefox has an experimental add-on for CSP but 
virtually no one uses it.


Doing dynamic content server side allows me to run that content through 
the enforcement filter server side thus catching policy violating 
content before it is ever sent to the user.


That itself, btw, is probably the biggest stress on the server.

I understand prototype etc. is the "web 2.0" way but I really don't have 
a high opinion of "Web 2.0". JavaScript, flash, etc. all have been used 
far too often to do bad things.


Right now, if I don't block except for white listed web sites, I end up 
with advertisements I don't care about expanding and covering the 
content I do care about. Unfortunately the web is full of jerks who do 
rude things with scripts, and people who do malicious things with scripts.


You wouldn't execute code that someone you don't know sent you an 
e-mail, would you? I wouldn't, nor do I execute code someone I don't 
know embeds in a web page.


I surf with script blockers (NoScript to be specific) and when I come 
upon web sites that don't properly function, I'm a lot liklier to head 
elsewhere than to enable scripting for that site. Since I surf that way, 
I expect others do as well, doing things server side that can be done 
server side allows users like me who block scripting to access the 
content without compromising the security of our systems.

You can't remove the empty fields server-side, as they never reach the
server. GET has a limit on the amount of data it may carry, which is
reduced the longer the base URL is. If you need to send large amounts of
data like that, you need to send it via POST. You can make minimal
changes to your PHP code to allow for this. If you use $_GET in your
PHP, swap it for $_REQUEST which contains both GET and POST data.

Re: [PHP] How do I remove unused GET parameters from the URL?

[Rene Veerman]

Michael, while i respect your choices, i think you should know that
jquery.com is pretty good at minimizing browser-incompatibility
headaches (and keeping js apps small), and the quircks that are left
are easy enough to learn about.

for things whereby
- the server needs to generate tons of HTML for a small(ish) dataset, or
- the client generates data (also to be translated to html) that the
server doesnt really need to know about (yet)

js can really take some stress off the server.

Another option is to use post in the form, and when your action page 
receives post, it redirects to itself with the used variables as get.

JavaScript is the only client side way I know of.
Use document.getelementbyid() and yank the unused nodes before submit.

server side, redirect - it shouldn't be that clunky.
Put in a hidden input that tells your action script to redirect to 
itself without the unused get variables (and w/o the hidden input).


That's how I would do it personally (opposed to js).

[PHP] How do I remove unused GET parameters from the URL?

[Daevid Vincent]

I have an HTML form with a hundred or so elements on it, used for searching

When the user submits the form (via GET) the URL is loaded with ALL of
these fields, and many of them are not even actually used in the search
criteria.

Close, but not quite what I need. On the Windows systems, the System
value is "Windows NT [hostname] [build]", so that just returns "NT".
Thanks, though. :-) You never know when something like that might be
useful.

I found php_uname('n') which looks like it will return the information
I'm after without having to dissect strings, and it appears to work
just fine across platforms.

Well, I looked at all the variables that are available.  Then I looked at the
data in the output of phpinfo().

The only place that I can find the information that you are looking for is
available in the "PHP Configuration" section and it is in the System 
information.

So, looking at the phpinfo() page, I noticed the first comment down had a
method/function for converting the output of phpinfo() into a multidimensional
array.  Taking the output of that users function, you can access the data the
data you are looking for.

So, here is a link to the phpinfo() page.

http://php.net/phpinfo

>From there, get the function called phpinfo_array()

take the output of that and run it through the following set of commands.

$data = phpinfo_array(TRUE);
list(, $server_name) = explode(' ', $data['PHP Configuration']['System']);
print( $server_name );

This will give you what you are looking for.

[PHP] How do I extract link text from anchor tag as well as the URL from the "href" attribute

[chrysanhy]

I have the following code to extract the URLs from the anchor tags of an
HTML page:

$html = new DOMDocument();
$htmlpage->loadHtmlFile($location);
$xpath = new DOMXPath($htmlpage);
$links = $xpath->query( '//a' );
foreach ($links as $link)
{ $int_url_list[$i++] = $link->getAttribute( 'href' ) . "\n"; }

If I have a link http://X.com";>, how do I extract the
corresponding  which is displayed to the user as the text of the link
(if it's an image tag, I would like a DOMElement for that).

[PHP] How do I Upload XML file using cUrl?

[Rahul S. Johari]

Ave,

I have a client who used Lead360.Com to manage their Leads. We have a  
Leads Management application in place that creates an XML file of the  
lead which give the client manually to download.


What are client is requesting is to POST the XML File directly to  
their Leads360.Com account. We have a POST Url from Leads360 where we  
can send the lead, but I'm not sure what kind of a cUrl script I need  
to use to POST an XML file. I've handled POST Data before using cUrl  
but I haven't written a cUrl script that uploads a file to a URL.


From what I have gathered so far ... this is what I have ...

[CODE]

$filename = "file.xml";
$handle = fopen($filename, "r");
$XPost = fread($handle, filesize($filename));
fclose($handle);

$url = "https://secure.leads360.com/Import.aspx";;
$ch = curl_init(); // initialize curl handle

curl_setopt($ch, CURLOPT_VERBOSE, 1); // set url to post to
curl_setopt($ch, CURLOPT_URL, $url); // set url to post to
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return into a variable
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml"));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 40); // times out after 4s
curl_setopt($ch, CURLOPT_POSTFIELDS, $XPost); // add POST fields
curl_setopt($ch, CURLOPT_POST, 1);

$result = curl_exec($ch); // run the whole process

[END CODE]

Am I on the right track here or am I missing something?

Thanks Guys!

Or pass it by reference to the functions, so that both are able to make

If a variable is local to a function, there is no way to access that
variable outside that function. You can pass it back as a return value
from the original function, or make it global (not advised) to make it
visible in other functions.

No, you can't. You either need to pass it back (recommended) or make it 
global (not recommended).



function tbl1($entrytitle, $entrytext)

{

global $conn;

$result= mysql_query("INSERT INTO tbl1(tbl1_id, title, text)

 VALUES('NULL', '$entrytitle', '$entrytext')", $conn);

 $tbl_id=mysql_insert_id($conn);// this is the local variable I'm setting 
to get the last auto increment id


return $tbl_id;

} 

 


Now I wish to access that variable in another function thus:

function tbl2($name, $entrytitle, $entrytext)

{


  $other_id = tbl1($entrytitle, $entrytext);
  echo $other_id;


global $conn;

$result =mysql_query("INSERT INTO tbl2(tbl1_id, name, title, text)

   VALUES('$tbl1_id', '$name', '$entrytitle', '$entrytext' )", $Conn); 


}

[PHP] How do I remove an array element from within a recursive function?

[Daevid Vincent]

I have an array like this and I simply need to recurse over it and find
a matching "menu" item to remove:

array(3) {

 ["dart"]=>
  array(10) {
[0]=>
object(menuItem)#4 (9) {
  ["menu"]=>
  string(7) "My DART"
  ["name"]=>
  string(7) "My DART"
  ["title"]=>
  string(39) "Data Analasys & Reliability Tracker"
  ["employee_only"]=>
  bool(false)
  ["page"]=>
  NULL
  ["children"]=>
  NULL
  ["parent"]=>
  NULL
  ["current"]=>
  bool(false)
  ["array_key"]=>
  string(4) "dart"
}
[1]=>
object(menuItem)#5 (9) {
  ["menu"]=>
  string(5) "Login"
  ["name"]=>
  string(5) "Login"
  ["title"]=>
  string(5) "Login"
  ["employee_only"]=>
  bool(false)
  ["page"]=>
  string(9) "login.php"
  ["children"]=>
  NULL
  ["parent"]=>
  NULL
  ["current"]=>
  bool(false)
  ["array_key"]=>
  string(4) "dart"
}
[2]=>
object(menuItem)#6 (9) {
  ["menu"]=>
  string(13) "Lost Password"
  ["name"]=>
  string(13) "Lost Password"
  ["title"]=>
  string(13) "Lost Password"
  ["employee_only"]=>
  bool(false)
  ["page"]=>
  string(12) "forgotpw.php"
  ["children"]=>
  NULL
  ["parent"]=>
  NULL
  ["current"]=>
  bool(false)
  ["array_key"]=>
  string(4) "dart"
}
...

I'm trying to remove ["menu"] == 'Login' from the array, but despite "finding" 
the element, it never removes.
isn't that what the & reference stuff is for?

menuItem::removeMenuItems($navArray['dart'], array('Login', 'Lost Password'));


public static final function removeMenuItems(&$menuItems, $removeArray)
{
foreach($menuItems as $value)
{
if (is_array($value->children))
menuItem::removeMenuItems(&$value->children, 
$removeArray);
else
{
//echo "*** CHECKING ".$value->menu." against 
".implode(',',$removeArray)." ***";
if (in_array($value->menu, $removeArray))
{
//echo "*** REMOVING ".$value->menu." 
***";
unset($value);
}
}
}
}

Hi!

Please note that most browser follows the RFC:s and does not allow more 
than two connections to each domain simultaneously. You can do 
work-arounds to solve this problem, like using subdomains for some 
requests. In Firefox you might also be able to disable this feature...

probably need to fix the apache.conf to allow more concurrent child

i'd imagine MaxClients is the one you will need to 'up'

also STW for 'apache prefork MPM'

  
sry, but that didn't fix things. it was already at 150 (i tried 250), 
and my webserver freezes on 1 to 3 open connections, can't tell for 
sure. but it's a real low number..



# prefork MPM
# StartServers: number of server processes to start

probably need to fix the apache.conf to allow more concurrent child processes.

also note I said 'processes' - php is not totally threadsafe (due to
unknowns in various extensions) and generally run under apache using the
[apache] pre-fork worker module.

it's apache that decides how many concurrent httpd processes are allowed to
run, php merely runs as a part of each httpd process in the form of
an apache module.

you could be running php as CGI or FastCGI SAPI, which is different to using the
apache module SAPI, but for the purposes on the above the same story goes.

and if it's not an apache config issue then I guess your looking at some
kind of OS limitation ... no idea about that I'm afraid.

Al, thanks for suggestion, but you're talking rubbish.  _All_ browsers
understand GIFs, and they are all LZW compressed.  There's absolutely
zero point in trying to gzip them as well.

Try by not LZW compressing and the use ob_start() and flush() so your files are gzip compressed. I 
don't know if Firefox knows how to readily handle LZW on the fly. It does know how to handle gzip.

Also, in case MARC goes down for whatever reason, there are a

http://dir.gmane.org/gmane.comp.php.general
http://www.nabble.com/PHP---General-f140.html
 and a ton of others which you can find on Google.

what is the thought behind php not providing access to original post

If you're with linux try netcat (nc) at listening mode.

Something like (not exactly)

nc -vtlp 80

and then submut against any localhost url.

[Olav Mørkrid]

hello


how can i get a raw and untouched printout of a multipart/form-data
POST? i need this to analyze what certain user agents do wrong when
uploading files.

what happens is that php just fails to put files into $_FILES, and
gives no way of seeing the original posting and exactly what is wrong
with it.

according to the manual, neither "always_populate_raw_post_data" nor
 work for multipart/form-data.

Re: [PHP] How do I specify a local file for fopen()?

[Cristian Vrabie]

Server can't access files on clients computers as they wish or it would 
be madness. Nothing would be secure. However you can get to the file if 
you make it public in some way and with some restrictions. Therea are 
several methods:
1. (wich i think is best) install a ftp server and "share" the file 
through the server. use the php's ftp function to access the file
2. install a webserver like apache and place the file you want in the 
web-root folder (the public on). use fopen or whatever you want to open 
the file.


you must keep in mind that in order to do this you have to have a public 
ip adress (you can't do it if youre behind nat)

How are you checking the value actually saved in the database -
through another PHP script, or directly via the MySQL
command-line-interface? If you're using another script to view the
value, it might be the display script that is screwing up, not the
save script - check the value directly with the MySQL CLI client.

Re: [PHP] How do I get PHP to save a backslash in a Mysql table?

[TG]

I didn't see all the responses to this, so maybe someone already recommended 
these things.

Looks like you may be over-complicating things in your code there.

First, if Magic Quotes are ON, then you probably want to stripslashes() to 
get rid of extra slashes.  If it's OFF, then don't worry about it.  (I 
think that's right.. been ages since I've had to deal with Magic Quotes so 
don't remember without playing with it).

Second.. you should be using, at minimum, mysql_real_escape_string() on all 
data items being inserted/updated/SELECT..WHERE'd, etc.  You can't trust 
user input or anything coming from the server.  Anything you don't type 
yourself as part of the query, that is.  Most of it can be forged.

And that "is_numeric" check shouldn't make a difference.  Even if it's 
supposed to be numeric data, you should still use 
mysql_real_escape_string() in case someone enters something bad (probably 
making it non-numeric, but you know... stick with a consistant data 
cleansing protocol).

Ok... quick recap...

Magic Quotes ON = extra slashes.. probably want to strip then before 
continuing.
Magic Quotes OFF = everything's cool.. proceed to 'standard operating 
procedure' (SOP) :)

SOP:
Use mysql_real_escape_string() on all data used in queries  (or the equiv 
function for your DB if it's not MySQL)

The only other thing to check is if you're viewing the echo'd results in a 
browser, you might do View Source to see exactly what's output.   Browsers 
will interpret things sometimes.  You might be able to enclose the output 
in  tags to get around that.   And make sure you're using 
single quotes in your echo, so things aren't being interpretted in the echo 
statement itself.

Some of these things are rare issues, but all things to check for if your 
output isn't what you expect it to be or want it to be.

most likely neither of the conditions in the function is getting hit and
mysql is removing the \ characters
from the original string.
try echoing out  $value before the update to see if it is what you expect.

I think "static module installation" means you've compiled PHP *in* to
Apache, and it's not a libphp5.so file -- It's just part of httpd
binary.

This step should tell you if it's copying libphp5.so into the Apache dir.

Yup, this is where you are compiling php INTO the httpd binary.


If you want to end up with a libphp5.so, you have to follow the
instructions that involve apxs and not the "Static" instructions.

Another possiblity, if you are trying to write this more generically,
would be to use:

?id[game]=$record->Game_id&id[Member]=$record->Member_id

$_GET['id'] will then be an array that looks something like this:
array('game' => 42, 'member' => 17);

You would then iterate through $_GET['id'] and show all the factors
that are going into the query/delete.

[PHP] How do I get Apache 1.3.36 to use PHP 5

[Beauford]

Not to sound like a total nob, but how do I get Apache 1.3.36 to use PHP5. I
have both 4 and 5 installed, but it still uses 4. I never had a problem with
4.

I read the followed the INSTALL file for PHP5, below. I reinstall Apache as
well and nothing - step 11.

I tried putting LoadModule php5_module /usr/local/apache/libphp5.so in my
http.conf, but it doesn't exist.

Any help is appreciated.

   Example 2-2. Installation Instructions (Static Module Installation for
   Apache) for PHP
1.  gunzip -c apache_1.3.x.tar.gz | tar xf -
2.  cd apache_1.3.x
3.  ./configure
4.  cd ..

5.  gunzip -c php-5.x.y.tar.gz | tar xf -
6.  cd php-5.x.y
7.  ./configure --with-mysql --with-apache=../apache_1.3.x
8.  make
9.  make install

10. cd ../apache_1.3.x

11. ./configure --prefix=/www --activate-module=src/modules/php5/libphp5.a
(The above line is correct! Yes, we know libphp5.a does not exist at
this
stage. It isn't supposed to. It will be created.)

12. make
(you should now have an httpd binary which you can copy to your Apache
bin d
ir if
it is your first install then you need to "make install" as well)

13. cd ../php-5.x.y
14. cp php.ini-dist /usr/local/lib/php.ini

Your URL contains 2 instances of a GET variable named, which you then 
use in the SQL query. In this instance $_GET['id'] will contain just the 
Game_id. Change the name of one or both IDs and you should be ok.

However, you should be using a complete URI in Location: to be within

You read the manual to learn basic PHP syntax.

header('Location: edit_property.php?property_id='.
  urlencode($property_id));

Also, technically the URL given in a location header should be absolute 
not relative.

Re: [PHP] How do I force my script to exit after 5 seconds?

Thanks very much, I've added stream_set_timeout functionality, and it 
seems to work very well!


For reference, here's the modified script:


$fp = fsockopen('192.168.3.25', 10001, $errno, $errstr, 5);
if (!$fp) {
echo 'Error...';
} else {
/** Set socket timeout period */
stream_set_timeout($fp, 5);

/** KPRINT outputs scale values */
$command = "KPRINT\r\n";

fwrite($fp, $command);

while (!feof($fp)) {
/** Check for timeout */
$info = stream_get_meta_data($fp);
if ($info['timed_out']) {
echo 'Timeout...';
break;
}

$buffer = fgets($fp, 1024);
}

fclose($fp);
}

Re: [PHP] how do I just escape double quotes within a string?

[tg-php]

You could use addslashes():
http://us3.php.net/manual/en/function.addslashes.php

Or, the code you mentioned below, could be rewritten like:
str_replace("\"","\\"",$code);
or
str_replace('"','\"',$code);

And if you're doing it for a MySQL query call, then you want to use 
mysql-real-escape-string() instead of all that mess above:
http://www.php.net/manual/en/function.mysql-real-escape-string.php

What's happening with the example you gave is that you're having a conflict 
with using the same type of string encloser (what's the proper word for single 
and double quotes in this case? hah).

""" = "" with a dangling ".  Error.

"\"" = a string containing just a double quote.

Everything inside "" is interpreted.

Everything inside '' is taken literally.

'"' = a string containing a double quote

''' = '' with a dangling ' on the end
'\'' = a string containing '  (I think.. I think this is the only exception to 
no-interpretation-within-single-quotes)

Some more information on single and double quotes here:
http://us3.php.net/manual/en/language.types.string.php#language.types.string.syntax.single

-TG

= = = Original message = = =

If I use add slashes, it strips everything, I just want to replace all the
double quotes with slash double quote but this, of course, throws errors:

str_replace(""","\"",$code);


Thanks!

Try this

$string = 'Hello "person." How are you?';
var_dump($string);
var_dump(str_replace('"', '\"', $string));

Notice you can use single and double quotes in the same string.

The pre-parser commands opens up a whole can of worms of complexity.

The issue has been resurrected since at least PHP 3.0 days, and
presumably before that.

The biggest stumbling block, imho, is that it goes against the grain
of the simplicity of PHP.

I'm sure that it could be done technologically.  But being able to do
something doesn't make it the Right Thing to do.

It sounds like we just need support for pre-parser commands.  You end

change attributes of the environment before script processing  
begins.  Then again, there's probably problems related to doing

I just don't get this...

You're going to recompile all of PHP to embed a string into the
executable to point to a different "php.ini" instead of just putting
that in your shell script somewhere?

Okay.

But many set_ini() are meant to be changed in real-time with the
execution of the script!

So you'd have to parse for only the set_ini() that has your particular
setting.

Plus, there's no law that the args to set_ini() can't be from a
database, or other dynamic data in a variable.  So you'd have to
execute the whole program to find out what the values are in some
cases.

Unless you want to pre-parse set_ini() for constants differently than
set_ini() for variables. [shudder]

If you think this should be implemented, feel free to take it up with
-internals@ or just submit a patch...

But I honestly think you haven't really examined this in enough detail
to understand why you're just not making sense here... :-)

Mebbe so, but that's equally obnoxious to pass this command line parameter
to a lot of existing scripts. It's just easier to re-compile and 'globally'
set the output_handler in a different php.ini file to what it used to be
before we optimized. This script issue has just started to rear it's ugly
head as we used to just use the default handler till recently. Our web pages
work great (obviously), but we've noticed strangeness with the CLI stuff.
Hence this dilemna.

I would agree if PHP used a one-pass parser. But there is a pre-parsing to
lint check and other 'setup' stuff. Seems that could utilize and prepare the
set_ini() for the second pass which runs the actual script.

Nothing is "impossible". It's just not implemented.

There is nothing to "re-compile" here.

The command line has an existing flag for you to specify the php.ini
file, or to override any setting[s] within the php.ini file.

Most of these ARE documented in that PER INI DIR page on php.net

This one probably is as well.

Bottom line, you can't step in the same river twice, and if php.ini
tells PHP to set up an ob_* handler before your script runs, it's
impossible to "undo" that just because you changed a setting that's
already been acted upon.

I suppose I could re-compile my command line version with a different
php.ini file, but that's kind of lame that I have to have two  
php.ini files

for what ini_set() SHOULD handle.


Would modifications via .htaccess work for you?
