Feature request - simple function to get variable name as a string - El Forum - 03-24-2011

Currently, I'm using a custom helper with this code.
But, I think this a necessary function that codeigniter needs to have built in, and loaded automatically... submitted for the kind consideration of the admins for inclusion in the next iteration of CI.

Can you give an example (in code) of where you would like to know the name of a variable, but you don't? I can't imagine needing a function like this...

I regret posting this request now. Indeed, Wizard, you are right, there is no situation where this would be needed. I was going to use this for inserting TRUE/FALSE values into a database depending on whether or not a corresponding checkbox was ticked. I thought this would be necessary, but I could achieve the same with a simple foreach $key = $value construct. Sorry for wasting all of your time.
Still though, the code I was about to use was:
Code:
<?php
function vname(&$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 $key => $val) {
if($val === $new) $vname = $key;
}
$var = $old;
return $vname;
}
?>It's in the PHP manual.

I saw the code, I just struggled to find a practical application, hence the question.
