In what ways can PHP scripts be optimized to handle large amounts of data processing for tasks like sending bulk email notifications?

To optimize PHP scripts for handling large amounts of data processing, particularly for tasks like sending bulk email notifications, you can utilize techniques such as batching the process, optimizing database queries, using proper indexing, and implementing caching mechanisms to reduce the load on the server. 

// Example code snippet for optimizing PHP script for sending bulk email notifications

// Batch the email sending process
$batchSize = 100; // Number of emails to send in each batch
$totalEmails = count($emailList);
$numBatches = ceil($totalEmails / $batchSize);

for ($i = 0; $i < $numBatches; $i++) {
    $start = $i * $batchSize;
    $emails = array_slice($emailList, $start, $batchSize);

    // Send emails in this batch
    foreach ($emails as $email) {
        // Send email logic here
    }
}

// Other optimizations such as database query optimizations, indexing, and caching can also be implemented
