It shoud be in your Power Panel mate..
I have whm/cpanel, can u tell where it is ?
Thanks
Do you have a Parallels Power Panel? Evey Dedicated and VPS has Power Panel, power panel is different from WHM and cPanel.
If you have a Power Panel like Parallels, Well it depends on the Linux distribution you are using, the version of php and the way you install it with Apache web server.
Php.ini may be here in your Power Panel
/etc/php.ini
Or here:
/etc/php/php.ini
/etc/php5/php.ini
Or here:
/usr/bin/php5/bin/php.ini
Hope that helps
