To embed the form in a web page, just copy and paste the HTML form code to the web page. For this simple contact form, we will make all the fields mandatory and will make sure that the email field is in the format: [email protected]
a regex alone on clientside, does not know if there is a mailserver nor if the domain itself exists.
I'm not sure about 5.3.4 final, but it is written that some 5.3.4-snapshot versions also were affected.

[email protected](16) "[email protected]" This feature is only available for PHP Versions (PHP 5 The description for FILTER_VALIDATE_URL seems incorrect/misleading.We will cover a few samples like validating e-mail address and URLs later. Here we will name it check_input and simply call this function whenever we need to validate simple input data: Note the check_input function at the bottom.What it does is takes the data passed to the function, strips unwanted characters (extra space, tab, newline) from the beginning and end of the data using the PHP trim() function, strips any quotes escaped with slashes and passes it through htmlspecialchars().it merly checks if the syntax of any email is valid or not.Its only to help the user writing the correct address. Most times you just want to validate that the user entered the email in the right format. So I like this better than the original answer but a Septik's answer is comprehensive and I up-voted that as well.
