How to pass a PHP variable using the URL

Question

I want to pass some PHP variables using the URL.

I tried the following code:

link.php

Answer 1

In your link.php your echo statement must be like this:

echo 'Link 2';

Then in your pass.php you cannot use $a because it was not initialized with your intended string value.

You can directly compare it to a string like this:

if($_GET['link'] == 'Link1')

Another way is to initialize the variable first to the same thing you did with link.php. And, a much better way is to include the $a and $b variables in a single PHP file, then include that in all pages where you are going to use those variables as Tim Cooper mention on his post. You can also include this in a session.
