Using variables from the global scope inside a function.

P: 39
I have the following php code, at the top I am pulling a piece of data from a query and I echo the results with no problem, I am using Ajax with this page as well and further down the page when I try to reference the same $radio it dosnt show anything.

Line 7 is where i get the current radio number assigned to the person that is loged in. and line 80 is where I try to use it again.


if ($myID==0) goto('../index.php');

$radio = sql::getval('use_rnumber', 'user', "WHERE `use_id`='$myID'");

echo "$radio";

$xajax = new xajax();
$xajax -> regf('updata');
$xajax -> processRequest();
$ajax = $xajax -> getJavascript("", "../includes/xajax/xajax_js/xajax_uncompressed.js");

function updata()
$objResponse = new xajaxResponse();
$objResponse -> assign('dinf', "innerHTML", get_mydata());
return $objResponse;

function get_mydata()

$code = "<table border=0 width=100% cellpadding=2 cellspacing=1 bgcolor=000000>";

Functions have 'local scope' and won't access the 'global' scope unless you tell it to.

Adding on to Ro's post:
inside the function set your variables with the keyword 'global'
Expand|Select|Wrap|Line Numbers
  1. func...
  2.     global $a, $x, $y;
EDIT: I'm an idiot and all the above is on
