<input type="submit">
</form>
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// Get input field value
$age = htmlspecialchars($_REQUEST['fage']);
// If input field is empty
if (empty($age)) {
// Display message "Age is empty"

// Else if input field is not empty
} else {
// Display age
echo $age;
}
