Validating form input php

Required field will check whether the field is filled or not in the proper way.

Most of cases we will use the * symbol for required field.

Each of these allies have their own perimeters which may or may not trust ours. As noted in the Introduction, we trust nothing and nobody.

The common phrase you will have seen in PHP is to never trust “user input”.

I'm doing an assignment in which I am required to use separate html and php files but am having trouble understanding how to validate my forms input as all examples I've found have both html and php in one file.

I've been following the example on w3schools: w3_example.html: Just a tip!

Validation means check the input submitted by the user.
