Fix version.

[2002-04-13 12:50 UTC] msopacua at idg dot nl

First update php.ini to reflect the correct extension dir. You're using a lib compiled with debug=1 and a php version without.

The extension dir, then changes.

What if you remove the zlib.so from your php.ini?

[2002-04-14 03:04 UTC] misiek at pld dot org dot pl

Doesn't change anything (category changed). It happens if _any_ of my php modules is loaded in php.ini...

My php is split in that way, see: ftp://ftp.pld.org.pl/test/i686/php* (ps. this is apache 1.3 version but I'm using this recompiled with apache 2.0.35).

[2002-04-14 08:15 UTC] sniper@php.net

So if there are NO extensions loaded in php.ini, it doesn't
crash? Did you compile those extensions same time you compiled the php you're trying to load them in?

[2002-04-14 09:00 UTC] misiek at pld dot org dot pl

I was debugging apache2+php brokeness and main php module was compiled from the same build after few modifications in TSRM.

Anyway recompilation of whole php fixed my problem. Thanks.
