PHP class to resize images using GD

ImageResizer

PHP class to resize images using GD, _(*1)

History

Although, I used a version of this class in a recent project, this is really just an exercise for me to create a simple PHP class library shared through Composer and Packagist., _(*2)

Setup

This package is available through Packagist with the vendor and package identifier the same as this repo., _(*3)

If using Composer, in your composer.json file add:, _(*4)

{
    "require": {
        "stormwild/image-resizer": "1.0.0"
    }
}

Otherwise:, _(*5)

include '/path/to/ImageResizer.php';

Because this class uses namespacing, when instantiating the object, you need to either use the fully qualified namespace:, _(*6)

$resized = \Stormwild\ImageResizer::resizer($path, $width, $height);

Or alias it:, _(*7)

use \Stormwild\ImageResizer;

$resized = ImageResizer::resizer($path, $width, $height);

Usage

    // possibly in controller action
    // check if image uploaded successfully
    // get path to uploaded image

    $path = "path/to/uploaded/file.ext"; // real path to file on server
    $width = 1050;
    $height = 700;    

    $resized = ImageResizer::resize($path, $width, $height);

    if($resized) {
        // upload to cloud storage
        // get url from cloud
        // save model with reference to image url
    }

The function resizes and replaces(updates) the uploaded file to the specified dimensions., _(*8)
