PHP Library to find images in several public repositories

Install

$ composer require ginsen/img-finder

Config file

With YAML format

Create a configuration file in yaml format, img-finder.yml, with the following content:

img-finder:
    repositories:
        ImgFinder\Repository\PexelsRepository:
            params:
                authorization: your-authorization  # Visit https://www.pexels.com/es-es/api/new/
        
        ImgFinder\Repository\UnsplashRepository:
            params:
                authorization: your-authorization  # Visit https://unsplash.com/developers

    # Optional
    translators:
        ImgFinder\Translator\DictionaryYaml:
            no_cache: true
            params:
                filename: img-finder/doc/examples/yaml_dictionary.yml

        ImgFinder\Translator\GoogleTranslate:
            params:
                apikey: your-credentials
                from: es
                to: en

With PHP format

Create config file with PHP is very similar at YAML, create php file format, as below.

<?php

use ImgFinder\Repository\PexelsRepository;
use ImgFinder\Repository\UnsplashRepository;
use ImgFinder\Translator\DictionaryYaml;
use ImgFinder\Translator\GoogleTranslate;

$settings = [
    'img-finder' => [
        'repositories' => [
            PexelsRepository::class => [
                'params' => [
                    'authorization' => 'your-authorization'  # Visit https://www.pexels.com/es-es/api/new/
                ]
            ],
            UnsplashRepository::class => [
                'params' => [
                    'authorization' => 'your-authorization'  # Visit https://unsplash.com/developers
                ]
            ]
        ],
        'translators' => [
            DictionaryYaml::class => [
                'no_cache' => true,
                'params'   => [
                    'filename' => 'img-finder/doc/examples/yaml_dictionary.yml'
                ]
            ],
            GoogleTranslate::class => [
                'params' => [
                    'apikey' => 'your-credentials',
                    'from'   => 'es',
                    'to'     => 'en'
                ]
            ]
        ]
    ]
];

And replace your credentials for use your contract services and delete the repositories that do not have credentials for their use.

If you do not have credentials to use GoogleTranslate remove this translator service, the dictionary does not need credentials, you can configure it to translate the search terms you want to English, such as a tag cloud. Note that the dictionary is not useful for free text searches.

Use

With YAML format

Create a config instance with the created yml file, and inject it into the main ImgFinder class.

$file = '/your/path/img-finder.yml';

$config = ImgFinder\Config::fromYaml($file);
$finder = new ImgFinder\ImgFinder($config);

With PHP format

With the PHP config file it is done as follows.

use ImgFinder\Repository\PexelsRepository;

$settings = [
    'img-finder' => [
        'repositories' => [
            PexelsRepository::class => [
                'params' => [
                    'authorization' => 'your-authorization'  # Visit https://www.pexels.com/es-es/api/new/
                ]
            ],
        ],
        // ...
    ]
    //...
];

$config = ImgFinder\Config::fromArray($settings);
$finder = new ImgFinder\ImgFinder($config);

Ready

ImgFinder is now available to query image repositories, just it only necessary to create a request.

Request in Pexels & Unsplash repositories

// Search in pexels ad unsplash repositories
$request = ImgFinder\Request::set('nature', ['pexels', 'unsplash']);

// same as:
/**
 * @param string      $words        The search term
 * @param array       $repositories The used repositories
 * @param int         $page         Page number
 * @param int         $perPage      Items per page
 * @param string      $orientation  Orientation: 'landscape' or 'portrait', default: 'landscape'
 * @param int         $width        Width of photos, default 1200 pixels
 * @param int         $widthSmall   Width of small photos, default 320 pixels
 */
$request = ImgFinder\Request::set('nature', ['pexels', 'unsplash'], 1, 10, 'landscape', 1200, 320);

Both requests are the same, "nature" is the search term, 1 is the default page, 10 is the number of response images for each repository, "landscape" is the orientation ('landscape' or 'portrait'), width is equal to 1200px and finally 320 is the width for thumbnails.

Request to search only in one repository

// Search in pexels repository
$request = ImgFinder\Request::set('nature', ['pexels']);
// same as:
$request = ImgFinder\Request::set('nature', ['pexels'], 1, 10, 'landscape', 1200, 320);

Search

Finally, you only need to perform the search.

$response = $finder->search($request);

This is the whole code of the entire operation.

use ImgFinder\Config;
use ImgFinder\ImgFinder;
use ImgFinder\Request;

$file = '/your/path/img-finder.yml';

$config = Config::fromYaml($file);
$finder = new ImgFinder($config);

$request  = Request::set('nature', ['pexels', 'unsplash']);
$response = $finder->search($request);

$imagesUrls = $response->toArray();

echo json_encode($imagesUrls);
/**
 * [  
 *    {  
 *       "author":     "Rodolfo Quirós",
 *       "url_author": "https://www.pexels.com/@rquiros",
 *       "media":      "https://images.pexels.com/photos/2219118/pexels-photo-2219118.jpeg?auto=compress&cs=tinysrgb&fit=crop&h=627&w=1200",
 *       "thumbnail":  "https://images.pexels.com/photos/2219118/pexels-photo-2219118.jpeg?auto=compress&cs=tinysrgb&h=350&w=320",
 *       "repository": "pexels"
 *    },{
 *       "author":     "Igor Starkov",
 *       "url_author": "https://unsplash.com/@igorstarkoff",
 *       "media":      "https://images.unsplash.com/photo-1595706480968-ca87913ee9c7?ixid=MXwxODk0OTN8MHwxfHNlYXJjaHwxMHx8YmVhdXR5JTIwZmFjZXxlbnwwfDB8fA&ixlib=rb-1.2.1",
 *       "thumbnail":  "https://images.unsplash.com/photo-1595706480968-ca87913ee9c7?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=MXwxODk0OTN8MHwxfHNlYXJjaHwxMHx8YmVhdXR5JTIwZmFjZXxlbnwwfDB8fA&ixlib=rb-1.2.1&q=80&w=320",
 *       "repository": "unsplash"
 *    },
 *    ....
 * ]
 */

Show all public repositories

To show all available repositories.

...

$finder = new ImgFinder($config);
$finder->repositories();

/**
 array:10 [
  0 => "pexels"
  1 => "unsplash"
 ]
 */

Cache optional

If you wish, you can cache requests to improve performance and not stress the image repositories.

For example, if you use the symfony/cache component you can inject it into the initial configuration.

Example:

$ composer require symfony/cache

Create Redis cache service.

use ImgFinder\Config;
use Symfony\Component\Cache\Adapter\RedisAdapter;

$redisConn = RedisAdapter::createConnection('redis://my.server.com:6379');
$cache     = new RedisAdapter($redisConn, 'imgfinder', 60);

$file   = '/your/path/img-finder.yml';
$config = Config::fromYaml($file, $cache);
