What are the potential pitfalls of embedding forms within loops in PHP scripts?

Embedding forms within loops in PHP scripts can lead to multiple form submissions if not handled properly. This can result in unintended data processing or duplicate form submissions. To solve this issue, you can use a unique identifier for each form within the loop to distinguish between them and prevent multiple submissions. 

<?php
for ($i = 0; $i < 5; $i++) {
    $formId = 'form_' . $i;
    echo '<form id="' . $formId . '" method="post" action="submit_form.php">';
    // Form fields and submit button
    echo '</form>';
}
?>
