数组中的自定义排序[重复]

Possible Duplicate: PHP custom sorting

I have an array,

Array
(
    [Flag]      =>  2
    [Pending]   => 11
    [Received]  => 11
    [Sent]      =>  8
    [Skip]      =>  5
    [Complaint] =>  1
    [Query]     =>  1
)

I have two requests for the above array:

1. How can I sort this into the order Received, Sent, Pending, Flag, Skip, Query, Request, Complaint.

2. As we see that "Request" is not available in the array, how do I push it into the array with the value zero?

$array = array
(
    "Flag" => 2
    "Pending" => 11
    "Received" => 11
    "Sent" => 8
    "Skip" => 5
    "Complaint" => 1
    "Query" => 1
);

$array["Request"] = 0;

function my_sort($a, $b) {
    $order = array("Received", "Sent", "Pending", "Flag", "Skip", "Query", "Request", "Complaint");
    return array_search($b, $order) - array_search($a, $order);
}

uksort($array, "my_sort");

print_r($array);

With the PHP function usort(), you can create a user-defined function and sort your array based on the results of this function.

Try usort, followed by,

$array['Request'] = 0;
