php isset problem

[Tom]

Why would the code below ouput hello when it shouldn't? It's as if it's setting $test='hello' before any of the checks. Is there any reason this could be happening? This is a small piece of code from a bigger script but I'm not using $test anywhere outside of this code, even in other includes etc.

if (isset($test)){echo test;}
if (!isset($test)){
    $test='hello';
}

Hi,

Which version of PHP are you using?

It would be more helpful if you pasted your entire code... although as much as you protest, it would appear that $test is being set in the global scope somewhere.

Put this before your code snippet and reply with the output:

var_dump($test);
exit();

ugh it's my fault, you're right, the code was in a file that I didn't realise was being included multiple times in a loop.
