No. But I can tell you that:
1) the reset() aren't necessary
2) even better, use a foreach-loop instead of while-loop

Use preg_* functions (Perl regex are more powerfull and faster)

Let say I have some strings
1) this is some domain.com test
2) domain.com
I can make this work either for first example of fo second, but not for
both. What I want is replace of domain.com to get
this is dome domain.com domain com test so replace should be
\1 \2 \3
so for second example I did /((.+)\.{1}(.+))/
How can I extend this to work in both.

Re: [PHP] Re: apache 1 vs 2 w/php
My experience dictates the contrary. Apache 2 is much faster with PHP that Apache 1.3. I run an enterprise web application in my company with about 950 users concurrently. I configured the apache logs to add the execution time for each request (this is done with %T in the LogFormat). We started the production system around 2 years ago with RH9 and Apache 1.3. Only 72% of the requests scored 0 seconds (which means less than 1 second). Then I updated to Fedora Core 2 with Apache 2 and it scored 96%. I know the kernel is a lot better but this improvement is almost because of Apache 2 since I tested Apache 1.3 in the same system and I got back to the 72% performance. I guess this dependes of what you use. Because PHP has an Apache filter and an Apache handler. I use the later. -William El mié, 05-01-2005 a las 14:20 +, Matthew Weier O'Phinney escribió: * Sebastian [EMAIL PROTECTED]: I am undecided whether to upgrade to apache 2 (currently running 1.3.33) I've heard some bad stuff (some good maybe) about using apache 2 with php.. does anyone have an opinions?

Re: [PHP] Re: apache 1 vs 2 w/php
Rasmus, I see much better performance with Apache 2. I'm not an expert in the internals of Apache nor PHP but I guess one of the improvements in apache is the log mechanism, I think it use a different technique that makes it faster that Apache 1.3 The reason I say this is because Apache 1.3 log are written in perfect order according to the time field.

If you are serving up a lot of static file, you will see an improvement. If it is all dynamic PHP requests, then you won't. Apache really doesn't have much to do on a PHP request so all the performance depends on the speed of PHP, not Apache. There are a few places where Apache2 has improved things for a PHP request, but these tend to be countered by a few places where things have gotten ore expensive. Every benchmark I have done puts PHP under Apache2 right in the same ballpark as PHP under Apache1 with Apache1 usually a little bit ahead. But do your own testing on your own platform.

Many of the accelerators give you access to their shared memory segments.

This is great. In my high performance web app I created a PHP library that abstracted this to use several backends. For instance I have a File backend and a SHM backend that uses the functions provided by the sysvshm PHP module. With this functions, do they need to serialize/unserialize every time I put/get something in/from the cache?? Also I use sysvsem for locking capabilities. does apc take care of the locking? does it have an API to do that? My experience with shared memory have been great. My production server uses a segment of 384MB to cache lots of resultsets and PHP objects and the performance is almost unbeatable... well if it serializes then pecl/apc will give better performance I guess. -William -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Additionally you can check the access time to see which of those sessions has been accessed in the last, let's say, 10 minutes or something. But there are several problems with this. Relying on session files is not good enough, they might be stored in a database or in shared memory. Other problem is that those sessions are for every PHP app installed in the server so you are counting sessions for different apps like it were from yours. To solve this you could put some APPID in the session and check for its value reading the sess file as text.

Re: [PHP] Persistent PHP web application?
Anything you do in the MINIT hook is basically free, so it would be trivial to load the data for the array from somewhere. Like a database, an xml file, etc. So you wouldn't need to hardcode a complex array structure in your MINIT hook, just have this generic little extension that creates an array (or object) from some external source. To change the data you would change that external source and restart your server, or you could write a PHP function in your extension that forced a reload with the caveat that each running httpd process would need to have that function be called since your array/object lives in each process separately. If you ask really nicely one of the folks on the pecl-dev list might just write this thing for you. Especially if you spec it out nicely and think through how it should work. -Rasmus Call me crazy or ignorant, i'm both, but would it be possible to build an extension that, in its MINIT hook as you suggest, actually runs a separate PHP script that contains global definitions, then makes those definitions available to later scripts? this is basically my original desire of having a one-time, persistent global include for each apache process. i realize you suggest pulling array data from a source like a DB or XML file, which would be a 90% solution for me, but the next step (a PHP script) just seemed logical/exciting... i realize i'm reaching with this, and it implies a conundrum (how does an extension run a PHP script if PHP hasn't fully started yet) but this kind of thing is just what makes me go and learn new things (C, php/zend internals) and I just might try to do it if it was feasible, for the fun of it, because it could be useful to lots of people, even if it took me a year or two to pull off. alas, this is a question for the pecl-dev list.

RE: [PHP] OpenSSL Problem
Richard, Actually, if you leave the code exactly as-is, but change the openssl_csr_sign function to create a self-signed certificate, the entire script executes perfectly. I know there is a lot of error checking needed - I'm just making a test script to get a feel for how OpenSSL operates in PHP. The certificate and key files are mode 444 (readable by everyone) as they are just test certificates right now. I have a valid openssl.cnf file (in /etc/ssl/openssl.cnf, which is what's complied into OpenSSL) and I use that configuration file that I use with some shell scripts to do everything that I want to do in PHP, so I'm sure it's a valid openssl.cnf file. Does PHP restrict access to /etc/ssl for the OpenSSL library if I have open_basedir set? Perhaps I need to make an openssl.cnf in the /usr/home/ws1086 (which is the open_basedir path) so that it's readable? I would think that the library would have access to the whole system since it's not really part of PHP, but maybe I'm wrong. Either way, it's not complaining about access to openssl.cnf, it's complaining about access to the certificate, so let's take it one step at a time. :) Tim Gustafson MEI Technology Consulting, Inc [EMAIL PROTECTED] (516) 379-0001 Office (516) 480-1870 Mobile/Emergencies (516) 908-4185 Fax http://www.meitech.com/ -Original Message- From: Richard Lynch [mailto:[EMAIL PROTECTED] Sent: Thursday, January 06, 2005 11:24 AM To: Gustafson, Tim Cc: php-general@lists.php.net Subject: Re: [PHP] OpenSSL Problem Gustafson, Tim wrote: I am trying to use the OpenSSL module for PHP on a FreeBSD 4.10 server.

If all else fails, despite the examples in the manual, you may want to try to get rid of the 'file://' parts of your file names. But maybe you need those for some arcane OpenSSL reason beyond my ken.

Re: [PHP] Image copying
Liam Gibbs wrote:
print(IMG ALT... HEIGHT... WIDTH... SRC = \ . copy_pic($sourcepic) .

So I'm calling the function straight from the SRC attribute of the IMG
tag. Here's what's in my function:
function copy_pic($sourcepic) {
if(file_exists($sourcepic)) {
$destinationpic = imagecreatetruecolor(imagesx($sourcepic),
imagesy($sourcepic));
imagecopy($destinationpic, $sourcepic, 0, 0, 0, 0,
imagesx($sourcepic), imagesy($sourcepic));
}
return $destinationpic;
}
After this, I'm going to be tampering with the pic, but I just wanted to
make sure I'm getting something, which I'm not. All I get is a broken
image. No error message, no nothing. Please tell me I'm not overlooking
some really idiotic thing, but I'm just having one heckuva time with this.
Not idiotic at all.
You have to sort of un-learn something, and wrap your brain around a new
concept. :-)
You know how PHP spits out HTML?
Yeah, well, PHP doesn't *just* spit out HTML.
PHP can *also* spit out an actual JPEG.
Like, it spits out what you would get if you opened up a JPEG in a text
editor and you see all that gobbledy-gook.
But to do this, you've *still* got to have it being spit out as *JUST* the
image, in a separate file, the *same* as having a separate JPEG image file
on the server which is not all that gobbledy-gook pasted into your HTML.
Or, to put it this way:
You currently have something like this all in one big file:
HTMLBODY
...
IMG SRC=JPEG%(**^#@@#R%GFGE#WWRYUIIUUYY**%*%$^[EMAIL PROTECTED]@#%$^%
...
/BODY/HTML
But, a valid setup would have *TWO* files. One with:
HTMLBODY
IMG SRC=otherfile.jpg/HTML
/BODY/HTML
otherfile.jpg would have the JPEG stuff in it:
JPEG%(**^#@@#R%GFGE#WWRYUIIUUYY**%*%$^[EMAIL PROTECTED]@#%$^%
So you need to move your copy_pic stuff and all of that to a DIFFERENT
file, say dynamic_jpeg.php.
Your HTML will then have:
IMG SRC=dynamic_jpeg.php
in it.
Plus your dynamic_jpeg.php file will have to have this stuff at the end:
header(Content-type: image/jpeg);
imagejpeg($destinationpic);
PS: You may not be *SEEING* the error messages, because they are buried
in the contents of what is supposed to be a JPEG. But if your JPEG looks
like this:
JPEG*(*^*^%^% PHP Error: blah blah blah **^%$$##@@#$%^^^
then it's just a broken JPEG, as far as the browser is concerned.
So surf *DIRECTLY* to it when the browser shows you a broken image icon:
http://sympatico.ca/dynamic_jpeg.php
for example.

New Year Resolution: Ignore top posted posts
Hi Jason:
Thanks for the reply.
I added some of the reset in just to make sure the pointer isn't somewhere
else through earlier iterations/to make sure it doesn't make a difference.
Will play around with the foreach as soon as I have some time. Reading
through php.net it seems like there are a few pitfalls (as there can be with
while) to watch out for.
Found out what the problem was after I posted. Reading through the function
manual for each I found the following:
snip
Caution
Because assigning an array to another variable resets the original arrays
pointer, our example above would cause an endless loop had we assigned
$fruit to another variable inside the loop.
/snip
That's what I did. Didn't had to but it has been a copy and paste from some
other code I haven't cleaned up. Good thing on it is, that I now know that I
can't do this.
Thanks again!

To change the data you would change that external source and restart your server, or you could write a PHP function in your extension that forced a reload with the caveat that each running httpd process would need to have that function be called since your array/object lives in each process separately.

George fixed it/rewrote it to work much better, but nobody was interested in his version either, so the current implementation isn't up to date anymore. The problem was likely that people really didn't understand how to use it and it is a rather unsafe thing to let PHP scripts fiddle with all the various Apache request hooks.

Dear all,
I recently started PHP OOP and I'm bit confused about best and the most
efficient methods when 'declaring a class' and 'calling function',
could somebody
explain me with following sample code, it would be great..
thanks..
class classLdap{
$rslt = $_POST['rslt'];
function ldapConnect($rslt){
..
return $rslt;
}// end function ldapConnect
function ldapAdd($rslt){
// i want to call ldapConnect($rslt) here what is the best
method.
$rslt = classLdap::ldapConnect($rslt);
This is generally done when you:
A) Don't have an instance of a classLdap to work with.
B) Calling ldapConnect() on the instance you have would cause side effects
to the instance (or other objects) that you don't want to happen in some
unusual case.
A. does not apply here, as you are in the method of the class, so you have
'$this' which is the instance you have created.
B. might or might not apply, but it all depends on YOUR application and
what you want it to do...
//or
//(curently i'm doing this way, it's to lengthy)
$new_classLdap = new classLdap;
$rslt = $new_classLdap-ldapConnect($rslt);
This can also be used to avoid altering the existing object you have
created -- though it's a bit more expensive than the previous way of doing
that.
There might be some super RARE case where you really really need an object
instantiated to have it be valid, and you would *HAVE* to do the above.
But that would be super rare, so this is probably not what you want.
//or
$rslt = $this-ldapConnect($rslt);
works if you just want to affect *THIS* same object that you have -- In
other words, use $this- when you are thinking about 'this' object that
you have created and want it to change itself in some way. Kind of like a
self-help sort of deal.
You might not want to assign the result back into $rslt -- depending on
what $rslt actually *IS* which I don't know, since you have it coming in
from $_POST...
Which you also need to do some checking on, since it's NOT SAFE to accept
$_POST data -- *any* Bad Guy out there could send any nasty thing they
want to your script through $_POST.
}// end function ldapAdd
}// end class
Based on what you are doing, and your experience level, I'd say stick with
the last answer:
$this-ldapConnect($rslt)
unless you have a very specific need to use the others.
Just keep it in the back of your mind that there *ARE* alternatives, so
that, years from now, when you run into one of those weird-o cases where
you need the others, you'll remember that they exist as alternatives.

Do you know what underlying libraries are associated with the extensions you want to use (in your list below)? If you do then you *should* be able to google for each library individually and see if that library is thread safe. I have not gone through this exercise for myself, but then again I don't need to either. ;) This would also be something that would be a great benefit to share with the PHP community if you decide to compile this list of thread-safe extensions. Keep in mind that it isn't that simple. If it was we would have done this long ago. Whether something is threadsafe depends on a lot of factors. The author of a certain library might tell you his library is threadsafe, but depending on how you compile it and which libc you are using it may or may not be threadsafe. So, while one person's library on his platform will work perfectly and be threadsafe, that exact same library on another platform may not be. Some examples of this are the c-client (imap) library and the postgresql library. Both may or may not be threadsafe depending on your platform and how you build them. Your crypt() libc call isn't threadsafe, for example. libpq used to call crypt() if you used the PASSWD() function in an SQL query. Now you might tick along for months without ever having 2 threads execute the SQL query that calls PASSWD() at exactly the same time, but then suddenly your lucky karma runs out and they do. You end up with 2 records in your database that are corrupted. The PostgreSQL guys fixed this, I think, but prior to this they were saying that libpq was threadsafe. The problem is always in code you don't control. They didn't control the libc crypt implementation and it bit them. I guarantee that there are dozens if not hundreds of examples of problems like this in just about every library, and probably a few left in PHP itself still. Unless someone hits a problem (which is likely) and recognizes it for what it is (which is unlikely) and informs the developers these tricky thread problems are never going to be fixed. I still content that humans are simply not smart enough to write threadsafe code for a largescale heterogenious project such as PHP with all the platforms and libraries that all have to interact perfectly. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Persistent PHP web application?
I think I understand where you're coming from. I've had a similar
problem and the best solution I've found is eAccelerator (previously
known as Turck MMCache). What EA does is keep the bytecodes PHP compiles
inshared memory so next time you need that script PHP doesn't need to
recompile, EA returns the bytecode from SHM. Now, since PHP scripts are
compiled and saved in SHM all I need to do is /save/ the data that does
not change often but requires a lot of queries as code (an array inside
a script) and include it whenever I need the data. No recompiling, no
need to touch the DB again, pure speed. I hope all this helps you. I
personally don't need extra processes and stuff like that but if you
really want all that you can take a look at phpbeans.

Dear list,
My web application (an online classifieds server) requires a set of
fairly large global arrays which contain vital information that most all
the page scripts rely upon for information such as the category list,
which fields belong to each category, and so on. Additionally, there are
a large number of function definitions (more than 13,000 lines of code
in all just for these global definitions).
These global arrays and functions never change between requests.
However, the PHP engine destroys and recreates them every time. After
having spent some serious time doing benchmarking (using Apache Bench),
I have found that this code takes at least 7ms to parse per request on
my dual Xeon 2.4ghz server (Zend Accelerator in use*). This seriously
cuts into my server's peak capacity, reducing it by more than half.
My question is: is there a way to define a global set of variables and
functions ONCE per Apache process, allowing each incoming hit to run a
handler function that runs within a persistent namespace? OR, is it
possible to create some form of shared variable and function namespace
that each script can tap?
AFAIK, mod_python, mod_perl, Java, etc. all allow you to create a
persistent, long-running application with hooks/handlers for individual
Apache requests. I'm surprised I haven't found a similar solution for
PHP.
In fact, according to my work in the past few days, if an application
has a large set of global functions and variable definitions, mod_python
FAR exceeds the performance of mod_php, even though Python code runs
significantly slower than PHP code (because in mod_python you can put
all these definitions in a module that is loaded only once per Apache
process).
The most promising prospect I've come across is FastCGI, which for Perl
and other languages, allows you to run a while loop that sits and
receives incoming requests (e.g. while(FCGI::accept() = 0) {..}).
However, the PHP/FastCGI modality seems to basically compare to mod_php:
every request still creates and destroys the entire application
(although the PHP interpreter itself does persist).
Essentially I want to go beyond a persistent PHP *interpreter* (mod_php,
PHP/FastCGI) and create a persistent PHP *application*... any
suggestions?
Thanks in advance for any help!

J. Whiting

My benchmarks (7ms+) are after the dramatic speedup provided by the
accelerator. I wouldn't even bother benchmarking this without the
compiler cache, but it is clear that a compiler cache does not prevent
PHP from still having to run the (ableit precompiled) array and function
definition code itself.

Plan on doing a LOT of testing -- My guesses on the probability of thread-safety were just that: GUESSES Thread-safe bugs are the kind of thing that can remain hidden for *YEARS* or even *DECADES* and not get triggered but once in a million executions of your scripts. By definition, they rely on *TWO* copies of your script running in parallel and timing is everything. For example, suppose your script is like this: ?php /* LOTS OF CODE */ thread_bug_function(); /* LOTS OF CODE */ ? You can run that script a million times, and nothing will go wrong. You can even run your web-server with multiple copies of your PHP script running a million times and nothing will go wrong. Let's examine the case of just *TWO* Apache children processes, running your script in parallel. Depending on when one script starts, when it gets interrupted by the OS so other processes can run, and when it re-starts, you have *THREE* possible cases: (where the time at which something is run is indicated in a vertical manner. CASE #1: APACHE CHILD ONEAPACHE CHILD TWO ?php ?php /* LOTS OF CODE */ /* LOTS OF CODE */ thread_bug_function(); thread_bug_function(); /* LOTS OF CODE */ /* LOTS OF CODE */ ? ? CASE #2: APACHE CHILD ONEAPACHE CHILD TWO ?php ?php /* LOTS OF CODE */ /* LOTS OF CODE */ thread_bug_function(); /* LOTS OF CODE */ thread_bug_function(); /* LOTS OF CODE */ ? ? CASE #3: APACHE CHILD ONEAPACHE CHILD TWO ?php ?php /* LOTS OF CODE */ /* LOTS OF CODE */ thread_bug_function(); thread_bug_function(); /* LOTS OF CODE */ /* LOTS OF CODE */ ? ? CASE #1 and CASE #2 cause no problem at all -- The 'thread_bug_function' doesn't run at the same time in one child as the other child, because of the timing -- it runs BEFORE or AFTER the same function in the other child. CASE #3 will crash big-time, because the thread-bug got executed at the SAME TIME in BOTH children. But here's the thing: The *larger* your code base, the better the odds are that CASE #1 and CASE #2 will happen, because there is so much going on in the /* LOTS OF CODE */ sections. The ONLY time the bug is triggered is when the two scripts happen to try to execute the buggy line AT THE SAME TIME. So CASE #3 is super super super rare. And it gets more and more rare as you add more and more code (yours or the PHP Modules you are asking about) to your project. The more you think about this, the more you'll realize just how impossible a question you are posing, and just how complicated you are making your server by using threads. There is NO PRACTICAL WAY to systematically test for a thread bug. Only disciplined coding by experienced software developers will avoid thread bugs -- and even that is hardly a given So you're really really really going out on a limb to use the threads. If you *NEED* the threads, you are going to have to pay a heavy heavy heavy price in doing a *TON* of testing under heavy load servers, with as much variance in timing of script start/end as you can introduce. Every line of code you add, and every Module you load in to add functionality/features will GEOMETRICALLY INCREASE your risk and the need for testing. The reason you kept getting bad answers, or answer at all, is you kept asking a bad question :-) Things to consider: #1. Do you really *NEED* threads? #2. If you *DO* need them, can you segment your application and modularize and isolate the thread usage to a single server, or a single body of code, or an isolated case that will be called rarely or ??? #3. Do you have the resources to run a billion tests? If you need threads, and you can't isolate them to a sandbox, and you don't have the resources for a billion tests, QUIT NOW.

The reason in this case is political/business: An ISP/host who wants to avoid a DOS attack by monster files being uploaded most likely doesn't want their clients to *over-ride* their DOS protection. Thus, PHP simply doesn't allow you to over-ride the setting. You can see which settings are valid in which place (php.ini, httpd.conf, .htaccess, ini_set) in the PHP manual. I'm also not sure that Apache/PHP can handle 20M in httpd.conf I'm not real sure where/when the 20M gets converted to 2000 in the process. But if the PHP code that *reads* php.ini is doing the conversion, then putting 20M in httpd.conf ain't gonna work. If the 20M is interpreted at a later point in the process, then it should work in httpd.conf So perhaps the real trouble here is that you need 2000 instead of 20M in httpd.conf Trying to change upload_max_filesize in .htaccess (or with ini_set) will be pointless. I do think that the INPUT HIDDEN still works but PHP takes the *MINIMUM* of the ISP's setting (in php.ini/httpd.conf) and the script (in HTML) You can *NOT* over-ride your host's anti-DOS setting. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] SSL
[EMAIL PROTECTED] wrote: Thinking of going from http to https on the server. My question is: Would there be any differences in my php-code from now? No. Well, maybe. You might want to use PHP to detect that you *ARE* on a secure connection. You also migth want to isolate your *need* for SSL to a specific set of scripts or a directory. SSL is slower, so increases load on your server. Maybe you have so little traffic that doesn't matter. But the PHP code itself is not needed to be any different. Though, of course, having SSL means little if your PHP code has inherent security holes. :-) It's all very well to use SSL to keep the data safe in transit from the browser to your web-server, but if you PHP scripts aren't handling the data securely after it arrives, what's the point? SSL is an armored car from the browser to your server. If you're not treating your server like a bank, with a detailed analysis of the processes and handling of the data, and where it goes, and how it gets there, and who has access, then it would be like a branch bank with no vault, no security guard, no alarms, no locks, ... The money's okay in that armored truck, but... So, in some sense, your PHP code may have to under-go *MAJOR* changes. More importantly, your entire business process, coding process, development process, data-handling processes, and skill-sets might need a major overhaul. Or not. You may be already doing everything perfectly securely. Certainly worth thinking about, though, eh? To summarize: There will be no TECHNICAL reason to change a single line of PHP. There could easily be a MAJOR business perspective overhaul required, or SSL is pointless. Hope that helps, though I suspect it only raised a much larger set of issues than what you had hoped for when you asked. :-) Sorry you asked? :-) :-) :-) -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] PHP 5 confusion
Hi,
Reading the PHP 5 documentation at: HYPERLINK
http://www.php.net/manual/en/language.oop5.basic.phphttp://www.php.net/man
ual/en/language.oop5.basic.php, I am confused.
In the example given, what is the difference between:
$assigned = $instance;
$reference = $instance;
I would expect all of the var_dump to display NULL
The doc says When assigning an already created instance of an object to a
new variable, the new variable will access the same instance as the object
that was assigned. so the above assignments seem the same to me and setting
$instance to NULL should also set $assigned to NULL.
If this is not the case and not using the '' specifies a 'copy'
(contradicting the documentation) then what's the purpose of object cloning?
I tried the code below and find that it gives the exact same output
regardless if I am using the '' or not so it seems to assign be reference
either way.
?php
class SimpleClass
{
// member declaration
public $var = 'a default value';
// method declaration
public function displayVar() {
echo $this-var;
}
}
$instance = new SimpleClass();
$assigned = $instance;
// $assigned = $instance; // No difference if this line is used instead
$instance-var = 'Value has been changed';
var_dump($instance);
echo 'br /br /';
var_dump($assigned);
?

[PHP] On large application organization [long and possibly boring]
Good afternoon gurus and gurettes,
If I have a large app what is the difference, other than having a very
large file, of doing this
switch($action){
/* several dozen cases to follow */
case foo:
writing out all of the code
break;
}
and this
switch($action){
/* several dozen cases to follow */
case foo:
include that will handle processing this case
break;
}
Correct me if I am wrong, but includes (and/or requires) will get all of
the code in all of the cases regardless if the case is being processed.
That being the case the code would essentially be the same length. Given
that, would there be an efficieny issue?
This would (the second way) also make the project easier to work on by
multiple programmers at the same time, similar to modular work being
done by programmers on C++ projects.
One of the reasons for doing this is so that global includes and certain
class definitions, such as an error checking function relavent to most
cases, can be included once.

[PHP] Compiling PHP with external mySQL libraries
1) Does adding 'shared,' as a ./configure option mean the module is compiled as an external, dynamically loaded module as compared to the module being statically linked into the 'exe' file? So that adding 'shared,' means I must add a line in the PHP ini file to load the extension (or load with a funcion call). 2) When configuring PHP with mysql support by something like '--with-mysql=/usr' does it automatically create a shared module? i.e do both these following configs produce the same result '--with-mysql=/usr' and '--with-mysql=shared,/usr'? The reason I ask, is I see many PHP info pages that specify '--with-mysql=[DIR]' without the 'shared,' bit, and they do specify an external library with the [DIR] part, but in the mysql info section 'MYSQL_MODULE_TYPE' shows as 'external'. I thought 'shared,' would have to be added to create an external dynamic loaded module? Thanks for the help!

Gustafson, Tim wrote: Actually, if you leave the code exactly as-is, but change the openssl_csr_sign function to create a self-signed certificate, the entire script executes perfectly. I know there is a lot of error checking needed - I'm just making a test script to get a feel for how OpenSSL operates in PHP. The certificate and key files are mode 444 (readable by everyone) as they are just test certificates right now. I have a valid openssl.cnf file (in /etc/ssl/openssl.cnf, which is what's complied into OpenSSL) and I use that configuration file that I use with some shell scripts to do everything that I want to do in PHP, so I'm sure it's a valid openssl.cnf file. Excellent! That does narrow your focus down, hopefully. Does PHP restrict access to /etc/ssl for the OpenSSL library if I have open_basedir set? Perhaps I need to make an openssl.cnf in the /usr/home/ws1086 (which is the open_basedir path) so that it's readable? I would think that the library would have access to the whole system since it's not really part of PHP, but maybe I'm wrong. You still may want to add the error-checking, at LEAST on the line that's giving you trouble, as the error string may have more information. Just for fun, for your test, you could even move those to a 777 directory. You might also need to have the PHP user's .ssh directories be created and have the right permissions for the keys to work. Can you 'su' to the Apache/PHP user and do the OpenSSL stuff from the command-line? Either way, it's not complaining about access to openssl.cnf, it's complaining about access to the certificate, so let's take it one step at a time. :) Except that you never know if a 'warning' message may have appeared earlier from a previous step. Perhaps you got a warning like: 'WARNING: openssl.cnf does not contain the blah-blah you need for an authenticated certificate' But you're not doing your error-checking. I've got NO IDEA if OpenSSL has different levels of errors like that, or if that's a possible error, and I've probably got the terminology wrong. What I *DO* know is, adding error-checking at every stage of the code where it is possible is usually the fastest easiest way to find out what went wrong. Thought sometimes just the act of writing the error-checking code makes you realize just what's going on, and prods the brain more than the actual code output. But error-checking is always good. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi,
Reading the PHP 5 documentation at: HYPERLINK
http://www.php.net/manual/en/language.oop5.basic.phphttp://www.php.net/man
ual/en/language.oop5.basic.php, I am confused.
In the example given, what is the difference between:
$assigned = $instance;
$reference = $instance;
I would expect all of the var_dump to display NULL
The doc says When assigning an already created instance of an object to a
new variable, the new variable will access the same instance as the object
that was assigned. so the above assignments seem the same to me and setting
$instance to NULL should also set $assigned to NULL.
Correct. Given only these assignments, $instance is NULL and so
$assigned and $reference would also be NULL.
If this is not the case and not using the '' specifies a 'copy'
(contradicting the documentation) then what's the purpose of object cloning?
This was pretty much only needed in PHP4. It might help you to read the
PHP4 OOP documentation notes. In PHP5 you don't need the to signify
an object as a reference; references are passed by default instead of
copies.
http://php.net/manual/en/language.oop.php
I tried the code below and find that it gives the exact same output
regardless if I am using the '' or not so it seems to assign be reference
either way.
?php
class SimpleClass
{
// member declaration
public $var = 'a default value';
// method declaration
public function displayVar() {
echo $this-var;
}
}
$instance = new SimpleClass();
$assigned = $instance;
// $assigned = $instance; // No difference if this line is used instead
In PHP5, the above comment is true. In PHP4, it is not true.
$instance-var = 'Value has been changed';
var_dump($instance);
PHP4: 'Value has been changed'
PHP5: 'Value has been changed'
echo 'br /br /';
var_dump($assigned);
PHP4: 'a default value' (if you use the , this would read 'Value has
been changed')
PHP5: 'Value has been changed'

[PHP] bizzare duplicate mail() call
Hello all - this problem is so wierd that I don't even know where to start. Hopefully you all can give me a couple leads. I have some reporting systems going on in various places on the server - mail() is called when a user does this or that. These scripts are farily simple, so I am next to certain is isn't the code - but every once in a while, more than one duplicate email will be sent. What is so strange is that it only occurs for these odd periods of time. For example, yesterday from 4pm to this morning at 7am, 2 copies would be sent. Last week for several days, 5 copies would be sent. The emails are frequent enough (every couple of minutes) that it is very easy to track, but I don't have a clue as to what would be the cause.

The sublassing is useful for testing when you want to test a change, a bugfix or a new design, and only a few pages change. The subclass would consist of an almost empty representation of the website containing only the changed files, thus allowing testing without harming the ordinary website. Is it possible ro postprocess the output of PHP for a specific page (e.g. for changing all links dynamically adding a prefix to a path, if that file does exist in the website subclass)?

Hi, has anyone got an example on howto use the shared memory functions ? I
currently serializeobjects of classes so they are cache and dont have to be
included upon
each request, i store thesein a session , its in a function called import heheh
, so
import('Package_Class'); , will get a class ina directory Package/Class.php
with the class name Package_Class , and
store that in a session.
would it be a quicker solution when unserializing to use the shared memory
functions instead ?

I've done some benchmaring and it is quite fast, specially compared to talking to the DB. Also, phpbeans provides a daemon that can give you the solution you are looking for, I believe. Adrian Hey I just checked out phpbeans, it looks pretty intense, it does have a php deamon that runs asthe server and the client connects to it via RMI based possible socket ? connections. It also lookslike you reference the object you want to display on the page like web-app/contact where contactis the possible class. This looks pretty interesting because i have currently ported alot of my codeto classes and still need a php script per page to execute the class via the constructor, this couldsimplify this process although i just checked how they add objects and i dont see any sharedmemory or session management for the objects ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You're wrong. The include() and require() statements are only evaluated when
they are reached in your application code, so there is a big difference between
your two examples. In you use the second example the code will only be included
by PHP if the application logic enters the case statement that contains the
include() statement. Here's a quick example to demonstrate this:
// 1.php
///
?php
$include = 0;
if($include)
include('2.php');
hello();
?
// 2.php
///
?
function hello() {
print Hello;
}
?
Save those two snippets into files named 1.php and 2.php. Pull up 1.php in your
browser and you'll see that the hello() function is undefined.

This would (the second way) also make the project easier to work on by
multiple programmers at the same time, similar to modular work being
done by programmers on C++ projects.
One of the reasons for doing this is so that global includes and certain
class definitions, such as an error checking function relavent to most
cases, can be included once.

Re: [PHP] Persistent PHP web application?
I think I understand where you're coming from. I've had a similar problem and the best solution I've found is eAccelerator (previously known as Turck MMCache). What EA does is keep the bytecodes PHP compiles inshared memory so next time you need that script PHP doesn't need to recompile, EA returns the bytecode from SHM. Now, since PHP scripts are compiled and saved in SHM all I need to do is /save/ the data that does not change often but requires a lot of queries as code (an array inside a script) and include it whenever I need the data. No recompiling, no need to touch the DB again, pure speed. I hope all this helps you.

Hope it helps, Adrian Madrid phpBeans looks interesting. after browsing the site a bit, looking at the introductory material and so on, i couldn't discern the way the phpbean server persists the beans, and, hence, if the solution would be fitting for what i'm looking for. what i'm looking for is a solution that will keep compiled zend variables and functions (the end result of executed php code that defines the variables and functions), in memory, without serialization, across multiple requests. if this is how the beans are kept persistent, i'm interested :) i'm going to try to find someone at phpbeans who can answer that. if others are interested, email me and i'll let you know what i find (if/when i find it)... /jw -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Slightly off topic but worth mentioning is:
If your $products array is generated dynamically, make sure it isn't
empty before running the query, MySQL does NOT like:
SELECT product_name FROM accessories WHERE product_id IN ()
The empty () will cause a MySQL error (it won't just return an empty
