How to bring all indexed array object into one associative array object

Question

I have a php array object $images if I print this array by print_r($images), I gets following structure.

Array
(
    [0] => stdClass Object
        (
            [image_name] => 1.jpg
        )

    [1] => stdClass Object
        (
            [image_name] => 2.jpg
        )

    [2] => stdClass Object
        (
            [image_name] => 3.jpg
        )
)

and I want to convert its structure as;

Array
(
    [image_name] => stdClass Object
        (
            [0] => 1.jpg
            [1] => 2.jpg
            [2] => 3.jpg
        )
)

Some one please suggest me a function to do that in php.

Why should it output an array with an object inside? Are you sure it should not just be an array? — Sverri M. Olsen

I think @SverriM.Olsen asked you you want output as stdClass Object normally array is used, just to clarify if it was a mistake. — bansi

You can do a simple loop.

$imagesArray = ['image_name' => new \stdClass()];
$counter = 0;
foreach ($images as $image) {
    $imagesArray['image_name']->$counter = $image->image_name;
    $counter++;
}

Explanation

I've first created an array $imagesArray with one element of stdClass, then I put the image_name as key. Then by using foreach loop of array of images $images, every $image is stdClass object, you just get the image_name property and assign it to the image_name object as $counter, which is just an integer.

$imagesArray will be an array not object

@VasilShaddix Yeah, its working. What you did? I mean Can you explain it. Thanx.

perfect! one trick: $imagesArray['image_name']->{$counter++} = $image->image_name; instead of 2 lines :)

@VasilShaddix, Now it is a good answer, some comment/explanation will make it great.

You create an array with one element of stdClass, i put the 'image_name' as key. Then you use foreach to loop through your array of images. Every $image is stdClass object, you just get the image_name property and assign it to the image_name object as $counter, which is just an integer.I wouldn't use such structure as @bansi suggested. Hope you could understand it.
