Calling a variable by passing variable name as a string

Question

I've got a list of variables. Let's call it a=1,b=2,c=3. I would like to pass the variable name to a function as a string and then retrieve its' value. Is there a way to achieve this in PHP? I', hoping to use this in page object pattern with Gherkin to pass a variable name to a gherkin step.

I've done this in c# using reflection before. Hard to think of a way to do this in PHP as I'm relatively new to PHP. — Pubudu

why actually should one need that? This sounds like a XY-problem to me — B001ᛦ

So you want to call my_function('my_variable') and then have my_function read the value of $my_variable from memory? — waterloomatt

You could manually build up the variable with ${'my_variable'} (stackoverflow.com/a/16339701/296555) but you'll still have to deal with scope issues. This approach is rarely a good idea. — waterloomatt

Why don't you use reflection in your test step to get the names of the arguments instead of adding unnecessary complexity to your application code? See an example here: stackoverflow.com/a/2692514/296555 — waterloomatt

I was able to resolve the problem by using ${$arg} notation as described by @waterloomatt above.
