创建一个PHP函数来显示HTML表单？

function displayForm() {
    echo '<form action="process.php" method="post">';
    echo '<label for="name">Name:</label>';
    echo '<input type="text" id="name" name="name" required><br>';
    echo '<label for="email">Email:</label>';
    echo '<input type="email" id="email" name="email" required><br>';
    echo '<input type="submit" value="Submit">';
    echo '</form>';
}
