Sort array - that specific values will be first

Question

I have a array. for example:

   array("Apple", "Orange", "Banana", "Melon");

i want to sort the array that first will be "orange", "melon". and the array will be

   array( "Orange" , "Melon","Apple","Banana");

i looked in PHP sort functions, didn't find a s sort function to do it.
what is the right way to do it.
thank you

What you looking for is usort, you can specify custom function to sort the array

example:

function cmp($a, $b)
{
    if ($a == "Orange") {
        return 1;
    }
    if ($b == "Orange") {
        return -1;
    }

    return strcmp($a, $b);// or any other sort you want
}

$arr = array("Apple", "Orange", "Banana", "Melon");

usort($arr, "cmp");
