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

• If you just want to sort the array values and don't care for the keys, use sort(). This will give a new array with numeric keys starting from 0.
• If you want to keep the key-value associations, use asort().

See also the comparison table of sorting functions in PHP.

Answer 2

You want the php function "asort":

http://php.net/manual/en/function.asort.php

it sorts the array, maintaining the index associations.

Edit: I've just noticed you're using a standard array (non-associative). if you're not fussed about preserving index associations, use sort():

http://php.net/manual/en/function.sort.php

Answer 3

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);

Answer 4

asort() - Maintains key association: yes.

sort() - Maintains key association: no.
