How can the maximum execution time error be resolved when trying to detect offline FTP servers in PHP?

The maximum execution time error can be resolved by increasing the maximum execution time limit in the PHP configuration or by using the set_time_limit() function in the code to extend the allowed execution time for the script. This will prevent the script from timing out before completing the task of detecting offline FTP servers.

// Set maximum execution time limit to 300 seconds (5 minutes)
set_time_limit(300);

// Code to detect offline FTP servers
