For example if I have

$color= "red";

So the variable color has the value of red. Is there anyway to extract the actual variable name from $color? (I just want the 'color' part) So that I could finally have something like:

$y = '$color';

my_function($field_name) {

$field_value = $_GLOBALS[$field_name]; // get value of field variable

// sample function action

echo '$'. $field_name .' contains the value: '. $field_value;

return;
// end sample

}

Now say you have $j, that has the value 5.

The following:

my_function('j');

Prints out:

"$j contains the value: 5"
