In this short snippet, you will learn how to easily get image width, height, and metadata in PHP. This can be achieved using the "getimagesize()" PHP built-in method.

getimagesize() method


This method accepts the image path and then will return an array of information. You can extract the value directly using the "list()" method and it's as follows.
<?php

list($width, $height, $type, $attr) = getimagesize("some-image.jpg");
The output of the above code will be like below.
[
    0 => 200,
    1 => 120,
    2 => 18,
    3 => 'width="200" height="120"',
    'bits' => 8,
    'mime' => 'image/webp',
]

getimagesize with Laravel Storage


Do note that you can also pass in the image path from the Laravel model like below. Imagine you have a Post model that store the path of the image that's located within the storage directory.
<?php

$path = storage_path('app/public/' . Post::first()->poster);

list($width, $height, $type, $attr) = getimagesize($path);
