如何按自定义顺序对Laravel Collection进行排序（非升降序）

Got it! To get your Laravel Collection sorted in that custom status order (2 first, then 1, then 3), you can use the sortBy method with a simple priority mapping. Here's exactly how to do it:

Step 1: Define your priority order #

First, create an array that assigns a numerical priority to each status. Lower numbers mean the item comes first:

$statusPriority = [
    2 => 0, // Status 2 gets highest priority (first)
    1 => 1, // Status 1 comes next
    3 => 2  // Status 3 is last
];

Step 2: Apply the custom sort to your collection #

Use the sortBy method with a closure that looks up the priority for each item's status. If your data is an array of arrays (like your example), use the array key to access status:

// Your original collection
$collection = collect([
    ["id" => 863368, "reference" => "Ref 1", "status" => 1],
    ["id" => 863391, "reference" => "Ref 2", "status" => 2],
    ["id" => 863390, "reference" => "Ref 3", "status" => 2],
    ["id" => 863396, "reference" => "Ref 4", "status" => 3]
]);

// Sort using the priority map
$sortedCollection = $collection->sortBy(function ($item) use ($statusPriority) {
    return $statusPriority[$item['status']];
});

If you're working with Eloquent models (where status is a property instead of an array key), just change $item['status'] to $item->status.

Step 3: Reindex the collection (optional) #

By default, sortBy preserves the original keys of the collection. If you want a fresh, sequential index, chain the values() method:

$sortedCollection = $collection->sortBy(function ($item) use ($statusPriority) {
    return $statusPriority[$item['status']];
})->values();

What the result looks like #

After sorting, your collection will be ordered exactly as you wanted:

1. Items with status 2 (Ref 2 and Ref 3)
2. Item with status 1 (Ref 1)
3. Item with status 3 (Ref 4)

This approach is super flexible—if you ever need to adjust the order later, just update the $statusPriority array and you're good to go!
