v2.0.0 2021-09-28 09:45 UTC

This package is auto-updated.

Last update: 2021-09-28 09:46:22 UTC



STARTING FROM v2.0 imgproxy-php supports advanced URL generation. See below.
imgproxy-php v2.0 is fully backwards compatible with v1.0, you should not have any issues with upgrading.
If those issues still occur with you, you're welcome to file a bug report, and even more welcome to create a pull request.

This is a small package which allows for generating URLs for your images that are resized by imgproxy:

$builder = new UrlBuilder("http://localhost:8080", "< your HEX key >", "< you HEX salt >");

// Generate imgproxy URL for an image, resizing to 300x200 with default settings (*)
$url = $builder->build("http://myimages.localhost/cats.jpg", 300, 200);

// By default, the URL is generated in basic mode
echo $url->toString();

// Customize URL params

// switch to advanced URL mode with tons of extra features, superior to the basic mode:

// set processing options:
$url->options()->withDpr(2)/* -> chain more with<FEATURE>() calls -> ... */;
echo $url->toString();

(*) default settings:

  • Mode: basic (apparently, basci mode is deprecated by imgproxy and possibly will be removed in future release)
  • Fit: fit
  • Gravity: sm (smart)
  • Enlarge: 0 (do not enlarge images)

Please refer to imgproxy docs for parameter descriptions and possible values.

Imgproxy PRO features

Certain features of Imgproxy are only available in the PRO version. Please refer to the docs and make notice of the PRO label on certain processing options. Using those options on a regular (non-PRO) instance of Imgproxy will result in "Invalid URL" response.

Testing in "real life"

In the root folder you will find docker-compose.yml file which will start imgproxy instance on port 8080. There is also a composer script generate with parameters:

  • base : string base URL
  • key : string IMGPROXY_KEY
  • salt : string IMGPROXY_SALT
  • source : string source image URL
  • width : int width
  • height : int height
  • advanced (no value required)

Once you started your local docker-compose stack with docker-compose up, you may call this script with the following command:

composer run-script generate -- \
  --base <imgproxy base URL> \
  --source <source image URL> \
  --key <IMGPROXY_KEY> \
  --salt <IMGPROXY_SALT>
  --width <width> \
  --height <height> \

# example:  
composer run-script generate -- \
  --base http://localhost:8080 \
  --source \
  --key 943b421c9eb07c830af81030552c86009268de4e532ba2ee2eab8247c6da0881 \
  --salt 520f986b998545b4785e0defbc4f3c1203f22de2374a3d53cb7a7fe9fea309c5

Hear, the KEY & SALT are valid for the imgproxy instance started by provided docker-compose.yml. You can also test URL generation for arbitrary custom imgproxy installation by providing relevant base, key & salt. Happy testing!
