How can the max_execution_time setting in PHP affect the execution of scripts that involve sending multiple emails?

The max_execution_time setting in PHP determines the maximum amount of time a script can run before it is terminated. If this setting is too low, scripts involving sending multiple emails may not have enough time to complete, resulting in incomplete email sending. To solve this issue, you can increase the max_execution_time setting in your PHP configuration to allow enough time for all emails to be sent.

// Set the maximum execution time to 300 seconds (5 minutes)
ini_set('max_execution_time', 300);

// Your code to send multiple emails here
