How can PHP be used to personalize newsletters for each recipient without causing timeout issues?

When personalizing newsletters for each recipient in PHP, the issue of causing timeout problems can be addressed by using batch processing. By breaking down the task into smaller chunks and processing a limited number of recipients at a time, the script can avoid exceeding the maximum execution time. This can be achieved by using a loop to iterate through the list of recipients and sending personalized emails in batches.

// Get list of recipients
$recipients = array("recipient1@example.com", "recipient2@example.com", "recipient3@example.com");

// Set batch size
$batchSize = 10;

// Process recipients in batches
for ($i = 0; $i < count($recipients); $i += $batchSize) {
    $batchRecipients = array_slice($recipients, $i, $batchSize);
    
    // Send personalized emails to batchRecipients
    foreach ($batchRecipients as $recipient) {
        // Code to personalize and send email
    }
}
