My goal is to echo the argument passed to a function. For example, how can this be done?
$contact_name = 'foo'; function do_something($some_argument){ // echo 'contact_name' .... How??? } do_something($contact_name);
Answer Snippets (Read the full thread at stackoverflow):
We overwrite the argument with a known.
We store the old value in a known variable * 2 .
* * behind the scenes: * * this function only works because we are passing the first argument by reference.

Static IsNullArgument(this Object o, string arg) { if (o == null) throw ArgumentNullException... .
You can always use an extension method to make it a little clearer .
This is the way a ton of Microsoft libraries handle the situation .
There is no other better way.

Some developers at my work refuse to even try it. I myself started TDD by trying to prove to one of my peers that Test Driven Development...

This is a practical way you could convince me that it was a good idea.)
No amount of argument will convince anyone argument I can put forward is that even I found my bugs before I got to a point of actually being able.

The interview questions were ...

As an argument is not passing by reference, its passing, by value, a pointer to some area of memory, after all, doesn't have references.

In the first case, start out with a complex area that rapidly changes and add unit tests.
One way to try and do so is to start with a localized area or a great scope.
Of investment.

$data is invalid JSON? (Either malformed or empty)
var_dump($data) will presumably show that $data is null .
