Re: [Phpgroupware-developers] Crash with win32 apache

[Peter]

Hello JeanEric,
I occasionally have the same problem with PHP and Apache under NT. The latest 
PHP seems error free. PHP 4.0.5 
was so bad I reverted to PHP 4.0.4.

In PHP 4.0.6, I had the problem when certain extensions were enabled, even if 
the extensions were not used in the script 
I was testing. With PHP 4.1.1, I use all those extensions and more but do not 
have the exploding Apache problem.

The problem is also caused by code with minor errors like missing semicolons 
and incorrectly used variables. PHP 
goes off in to a loop trying to find something and blows memory. PHP 4.1.1 does 
not explode Apache with syntax errors.

Look for instances where your code adds something to a global variable. With 
certain php.ini settings, you can end up 
with a variable going in to a global array and that variable itself being a 
global array, with the result being a loop. I found 
this with several open source applications when they try to register variables 
in sessions.

I test all code with PHP warnings on. For some errors, that brings up warnings 
before Apache explodes and you can fix 
the error. It is an extremely useful approach for all versions of PHP and found 
a few of the tricky errors in earlier versions 
of PHP 4.

I recommend PHP 4.1.1 with warnings on. My phpgw is an old version with about 
60 code errors found by turning 
warnings on. I started testing the latest version of phpgw with PHP 4.1.1 and 
have not had an Apache explosion.
