session_start causes Apache to crash (Win32, PHP 5.1.1)

[Vincent]

Hello,

Does anyone have a problem with Apache2 crashing after executing a PHP
script with session_start()? I notice if session_start() is placed
anywhere except at the start of the file, APache will crash. Can anyone
explain to me why? I don't want session_start to be at the start of the
file because I need to override some session methods. So session_start
has to happen after the declaration of custom session methods.

Can anyone please help? Thanks.

Vincent

session_start() must be called before any data is sent to the
browser.....just like header() or setcookie().

[joe]

if you're using cookie based sessions, session_start() must be called
before any data is sent to the browser....but in testing on a similar
setup (win2003/php 5.0.5/apache 2.0.55) I could not crash apache by
breaking that rule. your apache error logs might provide some help...

Is it Apache or PHP crashing?

What are the symptoms - error messages?

Do you mean a real full-blown crash, such as a segmentation fault and core
dump, or is it just an error?

What platform are you on?

There are instructions on http://bugs.php.net for getting a stack trace, which
you'd need to get to the bottom of a core dump:

Thanks for the replies.

The thing is Apache error log has nothing that indicates the crash.
It's Apache that crashs (with the standard Window error message that
Apache has terminated). I am on Windows XP.

I want to override my session methods to use my own database for
session handling instead of the default cookie handling. But after
declaration of those methods, and then run session_start, Apache
crashes.

Thanks for the suggestion on getting a stack trace. I will be doing
that shortly.
