What does the error message "maximum execution time of 30 seconds exceeded" in PHP mean?

The error message "maximum execution time of 30 seconds exceeded" in PHP means that a script took longer than the allowed time to complete its execution. This can happen when processing large amounts of data or running complex operations. To solve this issue, you can increase the maximum execution time limit in the PHP configuration or optimize your code to run more efficiently.

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