Ordering an array help

Hi

I'm crap with arrays.

I've installed a WP plugin and the plugin uses an array. I want to order the array, by length (longest to shortest).

For example (using sample data, printed, using print_r):

PHP Code:

---

Array
(
    [balance transfer credit card] => /balance-transfer-credit-cards|0|1|0|1|0|0|0|balance transfer credit cards
    [balance transfer credit cards] => /balance-transfer-credit-cards|0|1|0|1|0|0|0|balance transfer credit cards
    [amet] => /|0|1|0|0|0|0|0|Amet
    [low rate credit cards] => /low-rate-credit-cards|0|1|0|0|0|0|0|
    [credit cards] => /credit-cards|0|1|0|0|0|0|0|
) 


---

Would become:

PHP Code:

---

Array
(
    [balance transfer credit cards] => /balance-transfer-credit-cards|0|1|0|1|0|0|0|balance transfer credit cards
    [balance transfer credit card] => /balance-transfer-credit-cards|0|1|0|1|0|0|0|balance transfer credit cards
    [low rate credit cards] => /low-rate-credit-cards|0|1|0|0|0|0|0|
    [credit cards] => /credit-cards|0|1|0|0|0|0|0|   
    [amet] => /|0|1|0|0|0|0|0|Amet  
    
)

So, sorting (longest to shortest) the left side of the arrow ( => )

Thank you

Try this:

PHP Code:

---

<?php
$array = array(
    'ccc'        => 3,
    'bb'        => 2,
    'dddd'    => 4,
    'a'            => 1
);

function key_length_sort($a, $b){
    $a = strlen($a);
    $b = strlen($b);
    if($a === $b){
        return 0;
    }
    return $a < $b ? 1 : -1 ;
}

uksort($array, 'key_length_sort');

print_r($array);

/*
    Array
    (
            [dddd] => 4
            [ccc] => 3
            [bb] => 2
            [a] => 1
    )
*/

Let me know if you get stuck.

Anthony.

Yep, that works great, thanks!
I tried usort earlier, which didn't work. but uksort worked a charm.

Thanks.
