This video will help you to change the Maximum Execution Time (max_execution_time) value asscociated with PHP.
I'm using XAMPP for PHP development.
Open XAMPP Installation Directory (If your PHP development is not with XAMPP, Go to the respective program directory (WAMP, EasyPHP or any other Package!)
Goto 'php' subfolder
Open php.ini configuration file in any editor (Try 'Open With' option if this filetype doesn't have any default editor associated with)
Search for 'max_execution_time' variable in php.ini
Change the value to Something larger, Say 300 (5 minutes..:))
Save the file.
Restart Server. Thats it. It shoud Work..:)
Thanks.
