PHP max execution time: How to increase

Sometimes you might have noticed that certain PHP scripts that you wrote are not working as desired. A very common error message is Fatal error: Maximum execution time of 30 seconds exceeded.  The cause is the PHP restriction on the directive max_execution_time. But, it’s easy to adjust the PHP max execution time.

Firstly, the amount of time (in seconds) a PHP script is allowed to run is defined by the PHP variable max_execution_time. In most shared servers, the default configuration is 30 seconds. So, this article explains how a customer can modify the value of this variable if they need their PHP scripts to run for longer. We recommend not setting it very high.

How to solve Fatal error: Maximum execution time of 30 seconds exceeded

Firstly, log in to your cPanel account using your cPanel username and password. But, if you forgot the password, you can reset it any time using the ‘Reset Password’ option under the login box.

Scroll to the bottom and click on the ‘Save’ button for the changes to get into effect. This way, you will have a better PHP max execution time setting.
