Change collection index-CodePudding

This is Laravel collection question. I make a standard query to the database and get a collection. So far no problem.

Here result:

"id" => 1
"Certificate" => "001"
"Name" => "BTYUUU"
"Code" => "58X-AAAA-1G"

"id" => 2
"Certificate" => "002"
"Name" => "BTYSSS"
"Code" => "58X-SSS-1G"

But I want different arrange of result like this:

    [58X-AAAA-1G] => Array
        (
            [id] => 1
            [Certificate] => 001
            [Name] => BTYUUU
            [Code] => 58X-AAAA-1G
        )
        
    [58X-SSS-1G] => Array
        (
            [id] => 2
            [Certificate] => 002
            [Name] => BTYSSS
            [Code] => 58X-SSS-1G
        )

This is just draft. May be list in object is. Thanks for the help or advice

CodePudding user response：

You can use ->keyBy('Code'); on the collection.

https://laravel.com/docs/9.x/collections#method-keyby

CodePudding user response：

keyBy()

The keyBy method keys the collection by the given key. If multiple items have the same key, only the last one will appear in the new collection:

$collection = collect([
    ['product_id' => 'prod-100', 'name' => 'Desk'],
    ['product_id' => 'prod-200', 'name' => 'Chair'],
]);
 
$keyed = $collection->keyBy('product_id');
 
$keyed->all();
 
/*
    [
        'prod-100' => ['product_id' => 'prod-100', 'name' => 'Desk'],
        'prod-200' => ['product_id' => 'prod-200', 'name' => 'Chair'],
    ]
