PHP Form URL/E-mail

This lesson is part of PHP · All levels

Summary

The e-mail format and URL must be verified for the incoming data to be reliable. PHP provides built-in filters such as FILTER_VALIDATE_EMAIL and FILTER_VALIDATE_URL that are used together with filter_var(). This lesson also discusses how to handle non-validated scores.

Key points

Filter_VALIDATE_EMAIL checks the format of the e-mail address
Filter_VALIDATE_URL checks the format of the URL address
Returns when the value does not pass validation
Validation of the format is not a guarantee of existence, just making sure the form is correct.
