Custom ordering array with key / value pairs

Question

The following array arrives:

Array
(
    [66-507cddcd16d9786abafccfa78b19acf8] => XL
    [64-507cddcd16d9786abafccfa78b19acf8] => medium
    [65-507cddcd16d9786abafccfa78b19acf8] => large
    [63-507cddcd16d9786abafccfa78b19acf8] => small
)

How can I order the values of the array in ascending size order in such a way that the key / value relation is maintained? The array values may be some or all of the following

Small
XXL
Medium
Large 
XL

Answer 1

If you want to sort your values alphabetically, that's what asort is for.

Answer 2

you can use asort. I copied this fomr the php website

asort — Sort an array and maintain index association

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

Answer 3

If your sorting needs are more complex than asort or ksort as previously suggested, then write a function to plug into uasort.

Answer 4

You need to use uasort:

function sizeSorter($a, $b) {
    // customize as needed
    $comp = array_flip(array('xxxs', 'xxs', 'xs', 's', 'small', 'm', 'medium', 'l', 'large', 'xl', 'xxl', 'xxxl'));
    return $comp[strtolower($a)] - $comp[strtolower($b)];
}

uasort($array, 'sizeSorter');
