PHP $_GET not declared
<p>At my workplace, we have used a piece of code stored a remote server to do our Clickbank searches. Now my boss has decided to move everything over to our servers and has given lucky (heh) me the job to do it.</p>

<p>Now, I always thought that an $_GET variable needs to be declared within the local scope: $var = $_GET['var']; but in this code, it seems that the original programmer has just inserted the line right in, he's using $var in the code without declaring it... how is that possible?</p>
