Variables from link to php

Question

Hey,
Let's say I have 2 files, first is some kind of html website where i put a link (a href) to php(second) file. This second file contains a function which uses variables. Now is the question: Is it possible to open php file by clicking link with variables? Like <a href="something.php?a=5"></a> Or maybe there is another way to do this?

Answer 1

Shouldn't be a problem. Sending query strings is normal behavior, I'd just include the protocol ("http:" or "https:") so the browser doesn't guess.

This works on CodePlayground, e.g.:
<a href="https://www.google.com/search?q=SoloLearn+Codes">Click to query Google</a>
