Sort array by value alphabetically php

Question

As the title suggests i want to sort an array by value alphabetically in php.

$arr = array(
    \'k\' => \'pig\',
    \'e\' => \'dog\'
)

Answer 1

Note that sort() operates on the array in place, so you only need to call

sort($a);
doSomething($a);

This will not work;

$a = sort($a);
doSomething($a);
