Issue: Developers can efficiently troubleshoot and resolve issues with PHP installations and configurations by checking the PHP error logs for any error messages, ensuring that the PHP configuration file (php.ini) is correctly set up, and verifying that the necessary PHP extensions are installed.

// Check PHP error logs for any error messages
error_log("Error message");

// Verify PHP configuration file (php.ini) settings
echo php_ini_loaded_file();

// Check for necessary PHP extensions
$extensions = get_loaded_extensions();
print_r($extensions);
