What does the error message "Maximum execution time of 30 seconds exceeded" indicate in PHP?

The error message "Maximum execution time of 30 seconds exceeded" indicates that a PHP script took longer than the allowed time to execute. This can happen when processing a large amount of data or running complex operations. To solve this issue, you can increase the maximum execution time in the PHP configuration file or optimize the script to run more efficiently.

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