What are common reasons for PHP scripts not displaying output after form submission?

One common reason for PHP scripts not displaying output after form submission is errors in the PHP code, such as syntax errors or logic errors. Another reason could be issues with the form submission itself, such as incorrect form field names or missing form validation. To solve this issue, carefully review the PHP code for any errors and ensure that the form submission is correctly handling the input data. 

<?php
// Check for form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Display output
    echo "Hello, $name! Your email is $email.";
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <button type="submit">Submit</button>
</form>
