What are the potential pitfalls of using multiple forms in a loop in PHP?

Using multiple forms in a loop in PHP can lead to issues with form submission and processing, as each form will have its own set of input fields and submit button. To solve this, you can differentiate each form by adding a unique identifier to the form elements or using JavaScript to handle form submission. 

<?php
for ($i = 0; $i < 5; $i++) {
    echo "<form method='post' action='process_form.php'>";
    echo "<input type='hidden' name='form_id' value='$i'>";
    echo "<input type='text' name='input_field'>";
    echo "<input type='submit' name='submit_button' value='Submit'>";
    echo "</form>";
}
?>
