What Tedd means is this: ;-P
<?
function vname(&$var,$scope=false,$prefix='unique',$suffix='value') {
if($scope) {
$vals = $scope;
} else {
$vals = $GLOBALS;
}
$old = $var;
$var = $new = $prefix.rand().$suffix;
$vname = FALSE;
foreach($vals as $p => $v) {
if($v === $new) {
$vname = $p;
}
}
$var = $old;
return $vname;
}
?>
