How to Increase Max Execution Time in PHP: A Step-by-Step Guide for Ubuntu
When working with PHP scripts, there may come a time when you encounter the "maximum execution time exceeded" error. This typically occurs when a script takes longer to run than the allowed time. In PHP, this is controlled by the max_execution_time directive, which defines the maximum number of seconds a script is allowed to run before it is terminated. In this guide, we will guide you on how to increase the max_execution_time in PHP, specifically on Ubuntu systems.
Why Increase Max Execution Time?
The default maximum execution time in PHP is set to 30 seconds. This is perfect for most scripts, but some processes like heavy data imports, large file uploads, and other resource-intensive operations may require more time to complete. Failing to increase this limit for such operations can lead to incomplete or failed tasks, which is why knowing how to increase max_execution_time in PHP on Ubuntu is crucial.
Methods to Increase Max Execution Time in PHP
Editing php.ini File
The php.ini file is the main configuration file for PHP. Changes made here affect all PHP scripts globally.
Locate the php.ini file:

This sets the timeout to 300 seconds (5 minutes).
Save and Exit:
Save the changes and exit the editor (for nano, use CTRL + X, then Y, and Enter).
Using .htaccess File
If you're running PHP as an Apache module, you can update the max_execution_time for a specific directory using a .htaccess file.
Create or Update .htaccess File:
Navigate to your web application's root directory and open or create a .htaccess file:
