PHP syntax for dereferencing function result

Question

Background

In every other programming language I use on a regular basis, it is simple to operate on the return value of a function without declaring

Answer 1

You can't chain expressions like that in PHP, so you'll have to save the result of array_test() in a variable.

Try this:

function array_test() {
  return array(0, 1, 2);
}

$array = array_test();
echo $array[0];
