PHP Version, Execution Times and Memory Limit Configuration

Last updated on Apr 08, 2024

Managing a web hosting environment involves various configurations to optimize the performance and compatibility of your websites. Hostyt provides comprehensive tools and features in cPanel to manage PHP settings, catering to a wide array of needs from executing scripts efficiently to running applications requiring different PHP versions and increasing memory limits for robust script execution.

1. Changing PHP Version

Hostyt’s cPanel offers flexibility in selecting the PHP version specific to your website's requirements, enhancing security, performance, and compatibility.

  • Access the Software Section: Log into cPanel, navigate to the "Software" section, and locate the "Select PHP Version" tool.

  • Select and Set PHP Version: Choose the required PHP version and click "Set as current". You can also enable or disable specific PHP modules for the selected version.

  • PHP Options: In the "Options" tab, you can adjust settings like upload_max_filesize, max_execution_time, and more to suit your website’s needs.

2. Setting Custom PHP Execution Times

Increasing the PHP maximum execution time is necessary for running scripts that take longer than the default limit, such as site migrations or large file operations.

  • PHP Selector Tool: After logging into cPanel, use the PHP Selector tool to access php.ini values and locate max_execution_time.

  • Adjust Execution Time: Change the value to accommodate your script's needs, ensuring smoother execution of longer-running scripts.

3. Running Different PHP Versions on Subdomains/Addons

Hostyt enables you to configure specific PHP versions for subdomains or addon domains directly from the .htaccess file, ensuring compatibility across different parts of your website.

  • Edit .htaccess: Access the File Manager, navigate to the directory of your addon domain or subdomain, and edit the .htaccess file.

  • AddHandler Directive: Insert the appropriate PHP version handler, e.g.,
    AddHandler application/x-httpd-alt-php74___lsphp .php for PHP 7.4, or
    AddHandler application/x-httpd-alt-php56___lsphp .php for PHP 5.6, customizing the environment per directory.

4. Increasing PHP Memory Limit

Adjusting the PHP memory limit is crucial for scripts that require more resources, preventing errors related to memory exhaustion.

  • PHP Version Menu: In cPanel's "Software" section, select the PHP version menu and go to the Options for php.ini values.

  • Modify Memory Limit: Increase the memory_limit value as needed to support your website's operations, confirming changes with a success message.

Implementing PHP Configurations

These configurations empower you with the flexibility to tailor the hosting environment to your specific requirements. Hostyt's cPanel facilitates easy management of these settings, ensuring your websites run optimally. Remember to verify changes using a phpinfo() page and to revert or adjust configurations as needed based on website performance and functionality.
