• Testing and Development:
  • Developers can use the PHP Selector to switch between different PHP versions to test their applications in various environments before going live.

2. Performance Optimization

• Optimizing Resource Usage:
  • By adjusting PHP options like memory_limit and max_execution_time, you can optimize your PHP environment for better performance, ensuring that your site runs efficiently without consuming excessive server resources.
• Enabling PHP-FPM:

  • If a website is experiencing issues, you can use the PHP Selector to switch PHP versions temporarily to see if the problem is related to the PHP version.
• Debugging Extension Conflicts:
  • By enabling or disabling specific PHP extensions, you can troubleshoot and resolve conflicts or errors caused by incompatible or unnecessary extensions.

6. Enhancing Functionality

• Enabling Advanced PHP Features:
  • The PHP Selector allows you to enable advanced PHP extensions like mbstring, intl, or openssl, which may be necessary for certain applications, adding functionality without requiring custom server configurations.
• Adjusting PHP Behavior:
