EXTRACT function

[cpd259]

This may be a stupid question but I am interested.

I am looking at some PHP code on our system. I came across a line as follows:

       extract($_GET);

When I looked up the 'extract' function I saw that one of its parameters is suppose to be an array. How does $_GET play as a legal array for this function? What exactly is this pulling?

Thanks..Charlie

$_GET is a superglobal array, so of course it is a valid argument to [man]extract/man. That code kind of simulates register_globals.
