Zend

Hi, For my work, i bought Zend studio 5.2 and for sure when i installed it, it modified the path for the PHP.INI file to its local version. after checking the content of the php.ini file from Zend distribution, it seems to be a different version than the one from official PHP. I would like to switch to the previous location of php.ini (in original php folder) but i would like to know if someone experiment some issues by not replacing all data from php.ini (version of zend) inside the original php.ini file (from PHP distribution) ? I would be glad to be sure that i still can code and debug php code via Zend tool/ thanks a lot, Alain
