When using a variable variable in a class, $$this->varname does not
work, ${$this->varname} must be used.
Here is a simple script to show this in action. Put the {} in and it
will work:
<?
$id = "yes";
class testClass {
var $varname;
function testClass($varname) {
$this->varname = $varname;
}
function foo() {
global $$this->varname;
echo "$".$this->varname." is ".$$this->varname;
}
}
$test = new testClass("id");
$test->foo();
?>
