How can the PHP max_execution_time and memory_limit settings impact the performance of a script fetching emails from a POP3 account and inserting them into a database?

The PHP max_execution_time and memory_limit settings can impact the performance of a script fetching emails from a POP3 account and inserting them into a database by limiting the time and memory resources available for the script to run. To solve this issue, you can increase the max_execution_time and memory_limit settings in the PHP configuration file or within the script itself.

// Increase max execution time and memory limit
ini_set('max_execution_time', 300); // 5 minutes
ini_set('memory_limit', '256M');

// Your script to fetch emails from POP3 account and insert into database goes here
