What potential problem is indicated by the "Maximum execution time exceeded" error in the script?

The "Maximum execution time exceeded" error in a PHP script indicates that the script took longer to execute than the maximum allowed time set in the server configuration. This can be caused by inefficient code, long loops, or heavy database operations. To solve this issue, you can increase the maximum execution time limit in the PHP configuration or optimize the script to reduce the execution time.

// Increase the maximum execution time limit to 60 seconds
ini_set('max_execution_time', 60);
