Setting the PHP maximum execution time in .htaccess

The max_execution_time directive in PHP defines how long a script is allowed to run before it is terminated. By default, this value is set to 30 seconds. On ruachost.com, you can override this limit using a custom .htaccess file when you don’t have direct access to php.ini.

Why Change max_execution_time?

• Prevents scripts from timing out during long operations (e.g., large imports, backups, or heavy queries).

• Provides flexibility for applications that require extended processing time.

• Helps avoid errors such as:

  Fatal error: Maximum execution time of 30 seconds exceeded

Steps to Set max_execution_time in .htaccess

Step 1: Access Your Hosting Account

• Log in to cPanel or use FTP/File Manager.
• Navigate to your site’s root directory (e.g., /public_html).

Step 2: Create or Edit .htaccess

1. If .htaccess already exists, open it for editing.
2. If not, create a new file named .htaccess.

Step 3: Add the Directive

Insert the following line:

php_value max_execution_time 120

• Replace 120 with the desired number of seconds (e.g., 60, 300).
• Setting 0 allows unlimited execution time, but this is not recommended for shared hosting environments.

Step 4: Save and Verify

1. Save the .htaccess file.

2. Create a test file info.php with:

   <?php phpinfo(); ?>

3. Load it in your browser and search for max_execution_time.

4. Confirm the new value is active.

5. Delete the test file afterward for security.

Important Notes

• Not all hosting environments allow PHP directives in .htaccess. If unsupported, use php.ini or .user.ini.
• Incorrect syntax in .htaccess can cause 500 Internal Server Errors.
• Always back up your .htaccess file before making changes.

Best Practices

• Increase gradually (e.g., 60 → 120 → 300 seconds).
• Avoid setting excessively high values to prevent server overload.
• Monitor application performance after changes.
