What are some common techniques used for handling large forms in PHP applications?

Handling large forms in PHP applications can be challenging due to the amount of data being submitted. To address this issue, some common techniques include using pagination to break up the form into smaller sections, implementing client-side validation to reduce server load, and storing form data temporarily in a database or session to prevent data loss. 

// Example of implementing pagination for a large form in PHP

// Check if form data has been submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process and store the submitted form data
}

// Display the form using pagination
$currentStep = isset($_GET['step']) ? $_GET['step'] : 1;
if ($currentStep == 1) {
    // Display first section of the form
} elseif ($currentStep == 2) {
    // Display second section of the form
} elseif ($currentStep == 3) {
    // Display final section of the form
}

// Include pagination links
echo "<a href='?step=1'>Step 1</a> | <a href='?step=2'>Step 2</a> | <a href='?step=3'>Step 3</a>";
