How to get a variable name as a string in PHP? -

-

say have php code:

$foobar = "a string";

i need function this:

print_var_name($foobar);

which prints:

foobar

any ideas how achieve this? possible in php?

you use get_defined_vars() find name of variable has same value 1 you're trying find name of. not work, since different variables have same values, it's way can think of this.

edit: get_defined_vars() doesn't seem working correctly, returns 'var' because $var used in function itself. $globals seems work i've changed that.

function print_var_name($var) {     foreach($globals $var_name => $value) {         if ($value === $var) {             return $var_name;         }     }      return false; }

edit: clear, there no way in php, because shouldn't have it. there better ways of doing you're trying do.
