What are common reasons for receiving a blank page when submitting a form in PHP?

When submitting a form in PHP, a common reason for receiving a blank page is due to errors in the PHP code that processes the form data. This can include syntax errors, missing variables, or incorrect form field names. To solve this issue, you should check your PHP code for any errors and ensure that all form fields are correctly named and processed.

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    // Make sure to check for any errors in your PHP code
    // Ensure that all form fields are correctly named and processed
} else {
    // Display the form here
}
?>
