What are some common methods in PHP to handle page reloading after form submission?

When a form is submitted in PHP, the page is typically reloaded to process the form data. To handle page reloading after form submission, you can use methods such as redirecting the user to a new page, displaying a success message on the same page, or using AJAX to submit the form asynchronously without reloading the page. 

// Method 1: Redirecting to a new page after form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    header("Location: success.php");
    exit();
}
```

```php
// Method 2: Displaying a success message on the same page after form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    echo "Form submitted successfully!";
}
```

```php
// Method 3: Using AJAX to submit the form asynchronously without reloading the page
<script>
$(document).ready(function(){
    $("form").submit(function(e){
        e.preventDefault();
        $.ajax({
            type: "POST",
            url: "process_form.php",
            data: $(this).serialize(),
            success: function(response){
                // Handle success response
            }
        });
    });
});
</script>
