Question

I have an array that results in something like this: a = laranja b = banana c = maçã d = limao

Now I want to reorder it, but there is not something logical, like, d,c,b,a.
I want to just reorder the way i want. could be a,d,c,b or , c,a,b,d.

I tried sort, multisort, but without sucess.

Are there some advice?

I paste some code here to see if its helps

Answer 1

See sort()

$yourArray;
sort($yourArray);
print_r($yourArray);
// Now alphabetical

Also if you write a function to sort the values however you want, use usort()

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

$a = array(3, 2, 5, 6, 1);

usort($a, "cmp");

foreach ($a as $key => $value) {
    echo "$key: $value\n";
}
?>

0: 1
1: 2
2: 3
3: 5
4: 6

Edit:

Your foreach statement is kaput.

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

    $a = array("d"=>"limao", "a"=>"laranja", "b" =>"banana", "c"=>"maçã");
    print_R($a);
    usort($a, "cmp");
    print_R($a);
?>

Output:

Array
(
    [d] => limao
    [a] => laranja
    [b] => banana
    [c] => maçã
)
Array
(
    [0] => banana
    [1] => laranja
    [2] => limao
    [3] => maçã
)
