Can I get a variable name as a string?

montyauto · #1 (**permalink**) 22-02-2007, 02:55 PM

I've searching in php and perl for this:

how do i get a variable name as a string e.g i have a variable
myvar:1 2 5 3 2 6 7 8
i want to get "myvar"

Is there any function to get the name of a variable based on its value?

Where are you getting the name/value pairs from? A query string? Do you not know the variable names already?

I'm not sure how you do it in PHP or Perl but I'm sure there's a very simple 'get post data' function - in fact I know there is as I've seen it being used before. Google is your friend

It seems kind of backwards, but of course possible:

Code:

<?php
function get_var( $search )
{
        $def = $GLOBALS;
        foreach( $def as $k=>$d )
        {
                if( is_string( $GLOBALS[$k] ) && $d==$search )
                {
                        return $k;
                }
        }
        return false;
}
?>

And you would use it like:

Code:

<?php
$something = 'test var';
$varname   = 'more test var';

echo get_var( 'test var' );

This would output: something

Um... anyone know PHP?

I know PHP, why are you confused?
