How can the use of HTML5 input types like email and number affect form data submission in PHP, especially in Safari?

When using HTML5 input types like email and number, Safari may add additional validation to the form fields. This can cause issues with form data submission in PHP if the input does not meet Safari's validation requirements. To solve this issue, you can use the $_POST superglobal in PHP to retrieve the form data regardless of Safari's validation. Additionally, you can use PHP functions like filter_var to further sanitize and validate the form data. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
    $number = filter_var($_POST["number"], FILTER_SANITIZE_NUMBER_INT);
    
    // Use the sanitized form data as needed
}
?>
