Ok , i opened the Open phpinfo() , and it showed me these directorys for the php.ini which php.ini it using.
Configuration File (php.ini) Path no value
Loaded Configuration File C:\xampp\php\php.in
So i , took a php.ini ( it has all the needed apache mods enabled ) from the internet and replaced with the c:/xampp/php/php.ini . But when i go mysite/install.php it shows that i havent enabled the Zend Optimizer , but i have , i checked the php.ini file 10x times i have enabled the needed setting's !
So what the problem ?
