What is the potential issue with the PHP code provided in the forum thread regarding the maximum execution time exceeded error?

The potential issue with the PHP code provided in the forum thread is that it may be taking too long to execute, leading to the "maximum execution time exceeded" error. This error occurs when the script takes longer to run than the maximum allowed time set in the PHP configuration. To solve this issue, you can increase the maximum execution time limit in the PHP configuration or optimize the code to reduce the execution time.

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

// Your existing PHP code goes here
// Make sure to optimize the code to reduce execution time
