Changing of array format

Need Help
1

Hello World,

would like to learn how to change the array format from

     [
(int) 1 => 'Color Red Size 8 - $999.00',
(int) 2 => 'Color Blue Size 9 - $888.00',
(int) 4 => 'Color Red Size 10 - $999.00',
     ]

to this format

    Array
   (
   [0] =>
    (
        [id] => 1
        [name] => Color Red Size 8 - $999.00
     )
    [1] => 
    (
        [id] => 2
        [name] => 'Color Blue Size 9 - $888.00
    )
   [2] => 
    (
        [id] => 4
        [name] => Color Red Size 10 - $999.00',
    )
 )

the reason i would like to do so it because i l want to foreach this array to compare the ID with another table with if statement

            $id = 1

           foreach ($arrays as $object) :
              

                if ($object == $id) {

                    $result = $object;
                }

            endforeach;

can someone quide me how to change it?

thank you very much

There are any number of ways to do this. Probably the Hash class has some method that would work.

Personally, I’d use the Cake’s Collection::reduce()

        // untested but should do what you want
        $source =      [
            (int) 1 => 'Color Red Size 8 - $999.00',
            (int) 2 => 'Color Blue Size 9 - $888.00',
            (int) 4 => 'Color Red Size 10 - $999.00',
        ];

        $result = collection($source)
            ->reduce(function($accum, $value, $index) {
                $accum[] = ['id' => $index, 'name' => $value];
                return $accum;
            }, []);

        // or similar but slightly simpler, use the map() method
        $result = collection($source)
            ->map(function($value, $index) {
                return ['id' => $index, 'name' => $value];
            })
            ->toArray();

For more information: Collections - 4.x

Solving a problem like this is really a matter of style.

If you’re not comfortable with using callables yet, you could go super straight-ahead:

        $result = [];
        foreach ($source as $index => $value) {
            $result[] = ['id' => $index, 'name' => $value];
        }

You can see that does essentially what reduce() does.

the Cake’s Collection::reduce() is similar Typescript array reduce() , the Cake’s Collection::reduce() function returns the type of array was wanted.

thank you very much
