openfoodfacts-php

PHP API Wrapper for Open Food Facts, the open database about food.

Installation

With Composer:

composer require openfoodfacts/openfoodfacts-php

Usage

This is the most basic way of creating the API:

$api = new OpenFoodFacts\Api('food','fr');
$product = $api->getProduct('3057640385148');

In the example above you access the "food" database, limited to the French language/country scope. The first parameter is either

"food"
"beauty" or
"pet"

to decide which product database you want to use.

The second parameter decides the language/country scope of the chosen database: f.e. "world" or "de" or "fr".

For more details on this topic: see the API Documentation

These are all the parameters you really need for basic usage.

As return types for $api->getProduct you get an Document::class Object. This may also be an Object of Type FoodProduct::class,PetProduct::class, BeautyProduct::class depending on which API you are creating. These objects inherit from the more generic Document::class

In the example above, we use the 'food' API and there will get a FoodProduct::class

For getting a first overview the Document::class has a function to return an array representation(sorted) for a first start.

$product = $api->getProduct('3057640385148');
$productDataAsArray = $product->getData();

Optional Parameters

The other parameters are optional and for a more sophisticated use of the api (from a software development point of view):
