php sort() on array produces wrong result

Question

I want to sort an array that looks like this (to numerical order instead of 1, 10, 11):

Array ( [0] => 1.jpg [1] => 10.jpg [2] => 11.jpg [3] => 1         


        

Answer 1

sort() sorts the array in-place. Don't re-assign it.

Correct:

sort($this->pageLinks);

Incorrect:

$this->pageLinks = sort($this->pageLinks);
