How can the max_execution_time setting in PHP affect the sending of bulk emails using the mail() function?

If the max_execution_time setting in PHP is too low, it can cause the script sending bulk emails using the mail() function to time out before all emails are sent. 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 successfully. 

// Set max_execution_time to a higher value
ini_set('max_execution_time', 300); // 5 minutes

// Your bulk email sending code using the mail() function
for ($i = 0; $i < $total_emails; $i++) {
    // Code to send email
}
