在递归的每个步骤中向数组添加值

I have one simple question. How to push a value to the array in every step of recursion? I have a small script that gets content of 10 - 20 urls, gets the image url and it should everytime push the found image url to the array. How to do it?

Solved by rewriting the function to iteration instead of recursion.

$yourArray[] = $newElement;

This will push $newElement to the end of your array.
