How can the max_execution_time setting in PHP impact the successful sending of bulk emails, and what strategies can be used to work around this limitation?

The max_execution_time setting in PHP limits the amount of time a script can run before it is terminated. When sending bulk emails, especially if there are a large number of recipients, the script may exceed this time limit and fail to send all emails. To work around this limitation, you can break up the email sending process into smaller chunks and use a loop to send emails in batches. 

// Set a higher time limit or disable the max_execution_time setting
set_time_limit(0);

// Define the recipients and messages
$recipients = array('email1@example.com', 'email2@example.com', 'email3@example.com');
$message = 'This is a test email message.';

// Define the batch size
$batchSize = 50;

// Loop through the recipients in batches
for ($i = 0; $i < count($recipients); $i += $batchSize) {
    $batchRecipients = array_slice($recipients, $i, $batchSize);
    
    // Send emails to the batch recipients
    foreach ($batchRecipients as $recipient) {
        mail($recipient, 'Test Email', $message);
    }
}
