php global variables in drupal

Posted by helavissa on July 2, 2009 at 8:38pm

Hello,

I have a question (hopefully easy one) - how do I access a php global variable inside a function in Drupal?
For example, following code prints "Hello World", but why in Drupal it doesn't work?

<?php

    $test = "Hello World";
    
    function printVar(){
        global $test;
        echo $test;
    }
    
    printVar();
?>

Please help,
Thank you

try this

global $test;
$test = "hello world";

function printVar(){
  //print $GLOBALS['test'];
  global $test;
  echo $test;
}
printVar();

that works! Thank you
