Are there any specific functions in PHP that can help with dividing email addresses for bulk sending?

When sending bulk emails, it's important to divide the email addresses into smaller batches to avoid hitting rate limits or causing server overload. One way to achieve this is by using the array_chunk() function in PHP, which splits an array into chunks of a specified size. 

// Sample array of email addresses
$emailAddresses = ['email1@example.com', 'email2@example.com', 'email3@example.com', 'email4@example.com', 'email5@example.com'];

// Split the email addresses into chunks of 2
$chunks = array_chunk($emailAddresses, 2);

// Loop through each chunk and send emails
foreach ($chunks as $chunk) {
    // Send emails to the addresses in $chunk
    foreach ($chunk as $email) {
        // Send email logic here
        echo "Sending email to: $email\n";
    }
}
