What does foo[] mean in $this->foo[] in php

Question

Is foo[] an array?

In the following code is an array element being assigned to foo[]? And is there an array key that is automatically associated with it?

$this->foo[] = 'hello world';

no this is same as pushing elements to array – Madhawa Priyashantha Jun 20 '16 at 02:03 — Madhawa Priyashantha, Jun 20 '16 at 02:03

This is adding an element to the end of the foo array.

It's the same as using array_push().
