here's what i've done i'll get to the problem last.
1) installed apache 2.0.48
2) installed mysql 4.016
3) installed php 4.3.4 as binary
copy php4apache2.dll (from the sapi folder) and php4ts.dll to the modules folder in the Apache directory.
Then open the httpd.conf file (conf folder) and paste these lines into it:
LoadModule php4_module modules/php4apache2.dll
AddType application/x-httpd-php .php
DirectoryIndex index.html index.html.var
added: index.php (resp. index.php3 etc.) to the end!
extension_dir = ".\" to
extension_dir = "x:\php4\extensions\" with x and php4 being the path to your PHP4 installation.
I changed those things in the httpd.conf file
and in php.ini i changed Directory in which the loadable extensions (modules) reside.
to
extension_dir = "c:\php\php-4.3.4-Win32\extensions"
So now i don't get the server crash that i did before but i still can't open php files. what's wrong any ideas?
