Changes in php.ini have no effect

(sorry if this post is a double for you, but I didn't get it and it doesn't exist in the archive - so I assume it was never posted before) The following is a question that seems obvious, but somehow manages to elude me until today ... :-} hopefully someone here could point out my stupidity in this case. Problem: Changes made in c:\winnt\php.ini doesn't have any effect even after restarting Apache. Steps tried: # looking for other copies of php.ini - none found # entering the related values in Apache's httpd.conf file instead - works for some values, but not for others. # entering the related values in Apache's .htaccess file - doesn't work at all PHP version: 4.3.3 phpinfo() output - http://www.harrysufehmi.com/inf.php If you at the output of phpinfo(), it stated that the configurations were read from c:\winnt\php.ini - but it got several different config, such as: # php is installed at c:\php\php-4.3.3\ --- not c:\php4 # extension_dir is set to c:\php\php-4.3.3\extensions\ in php.ini --- but phpinfo() says different things # php_gd2.dll is enabled, but not according to phpinfo() Any pointer will be very much appreciated.
