Description:
------------
The configuration file is not read.
I compiled PHP --with-config-file-path=/etc/httpd and without it. 
I have put a php.ini at /etc/httpd and /usr/local/lib and many more places.
Always did a restart of apache.
I also gave all rights to php.ini.

Reproduce code:
---------------
echo "get_cfg_var('cfg_file_path') = " . get_cfg_var('cfg_file_path'); 

/* and this to check little changes in php.ini */
phpinfo();

Expected result:
----------------
the path to php.ini

Actual result:
--------------
compiled without '--with-config-file-path=/etc/httpd' my phpinfo says 
Configuration File (php.ini) Path: /usr/local/lib

But changes in php.ini there have no effect.
