FILTER_VALIDATE_URL allows:filter_var('javascript://comment alert(1)', FILTER_VALIDATE_URL); Where the (URL encoded newline), in certain contexts, will split the comment from the JS code. Keep in mind that FILTER_VALIDATE_EMAIL will validate the email address according to standards.

The range options are also smart enough to recognize when the boundaries are exceeded in different bases.

Here's an example: Notice that filter_var with FILTER_VALIDATE_EMAIL does not work if you are trying to get a String from an XML document e.g. I often use XML files as configuration files and use a function that returns a string from the config file via xpath.

If you need to validate a larger number, obviously there's a fee.

You CAN send an email to an address and see if you get a bounce back, but that does not appear to be what you are asking.I emailed that company so I could learn something about what is really being done and here is the response I received . Essentially, the mailboxlayer API verifies email addresses using SMTP (Simple Mail Transfer Protocol), which is the protocol we all use in order to send and receive emails.Very similar to pinging a URL to verify the existence of a web server, our API makes use of mail servers' SMTP conversations in order to determine whether or not a individual email address is actually allotted to a user.Note that both (string) FALSE and FALSE are not recognized as boolean values and will return NULL (not FALSE as you might expect).I thus personally suggest that (to date) the best way to take the filter_var()-functions beyond their original purpose (and allow future extension and customization) is to wrap them in your own classes.

This will allow you to work-around unexpected behavior on non-string input and add your custom checks, or back-port filters or sanitizers that may be added in later versions of PHP.(Especially since PHP currently still lacks filters and sanitizers for some of the more exotic HTML5 input types, like "color".
