FasterImage

FasterImage finds the dimensions or filetype of a remote image file given its uri by fetching as little as needed, based on the excellent Ruby implementation by Stephen Sykes and PHP implementation by Tom Moor., _(*1)

FasterImage uses the curl_muli* suite to run requests in parallel. Currently supports JPG, GIF, PNG, WEBP, BMP, PSD, TIFF, SVG, and ICO files., _(*2)

Usage

        $client = new \FasterImage\FasterImage();

        $images = $client->batch([
            'http://wwww.example.com/image1.jpg',
            'http://wwww.example.com/image2.gif',
            'http://wwww.example.com/image3.png',
            'http://wwww.example.com/image4.bmp',
            'http://wwww.example.com/image5.tiff',
            'http://wwww.example.com/image6.psd',
            'http://wwww.example.com/image7.webp',
            'http://wwww.example.com/image8.ico',
            'http://wwww.example.com/image9.cur',
            'http://wwww.example.com/image10.svg'
        ]);

        foreach ($images as $image) {
            list($width,$height) = $image['size'];
        }

Install

composer require fasterimage/fasterimage, _(*3)

Alternatively, add "fasterimage/fasterimage": "~1.5" to your composer.json, _(*4)
