I installed PHP GTK in C:\\php-gtk but when I go to run it like from the command line like this
cd C:\\php-gtk2
php demos\\phpg
Just solved the problem.
I was trying to run the demo script from the demos folder. But when I tried it with the same folder where the php.exe is it ran smoothly. So there is no problem with the php-cli.ini or no need to worry about this error "Please load the php-gtk2 module in your php-cli.ini"
So Goodluck with PHP-GTK.
