Re: $GLOBALS

> i´m new in PHP. What does the expression: > $ref=$GLOBALS["HTTP_GET_VARS"]["ref"]; > $id=$GLOBALS["HTTP_GET_VARS"]["id"]; > do? It gives you the content of the querystring variable ref and id. eg. page.php?id=20&ref=value > What is $GLOBALS? $GLOBALS is an array wich contains all the varibles in the "global variable scope". http://dk.php.net/manual/en/language.variables.scope.php You can get an overview of all the variables by using the print_r() function: print_r($GLOBALS); http://dk.php.net/manual/en/function.print-r.php > What are the parameters ["HTTP_GET_VARS"]["ref"]? ["HTTP_GET_VARS"] is also an array, and it contains alle the variables from the querystring. And ['ref'] is a querystring variable. /Emil -- Emil Rasmussen http://noget.net
