What best practices should be followed when generating forms within a while loop in PHP?

When generating forms within a while loop in PHP, it is important to ensure that each form element has a unique name attribute to differentiate them when the form is submitted. One common approach is to append the loop index to the name attribute to make it unique. This way, when the form is submitted, you can easily identify which form element corresponds to which iteration of the loop. 

<?php
// Sample code demonstrating how to generate unique form elements within a while loop

// Assuming $results is an array of data fetched from a database
$results = [...];

// Start the form
echo '<form method="post">';

// Loop through the results and generate form elements
$i = 0;
while ($row = $results->fetch_assoc()) {
    echo '<input type="text" name="input_' . $i . '" value="' . $row['value'] . '"><br>';
    $i++;
}

// Close the form
echo '<input type="submit" value="Submit"></form>';
?>
