Getting Started

Supported platforms

This library is compatible with PHP version 5.3 and later.

Install

With composer (Recommended)

Install the package via Composer:

composer require algolia/algoliasearch-client-php

Without composer

If you don't use Composer, you can download the package and include it in your code.

require_once('algoliasearch-client-php-master/algoliasearch.php');

Framework Integrations

We officially provide support for the Laravel and Symfony frameworks:

If you are using one of those two frameworks have a look at our Laravel documentation or Symfony documentation

Quick Start

In 30 seconds, this quick start tutorial will show you how to index and search objects.

Initialize the client

To begin, you will need to initialize the client. In order to do this you will need your Application ID and API Key. You can find both on your Algolia account.

// composer autoload
require __DIR__ . '/vendor/autoload.php';

// if you are not using composer
// require_once 'path/to/algoliasearch.php';

$client = new \AlgoliaSearch\Client('YourApplicationID', 'YourAdminAPIKey');

$index = $client->initIndex('your_index_name');

Push data

Without any prior configuration, you can start indexing 500 contacts in the contacts index using the following code:

$index = $client->initIndex('contacts');
$batch = json_decode(file_get_contents('contacts.json'), true);
$index->addObjects($batch);

Configure

Settings can be customized to fine tune the search behavior. For example, you can add a custom sort by number of followers to further enhance the built-in relevance:

$index->setSettings(['customRanking' => ['desc(followers)']]);

You can also configure the list of attributes you want to index by order of importance (most important first).

Note: The Algolia engine is designed to suggest results as you type, which means you'll generally search by prefix. In this case, the order of attributes is very important to decide which hit is the best:

$index->setSettings(
    [
        'searchableAttributes' => [
            'lastname',
            'firstname',
            'company',
            'email',
            'city',
            'address'
        ]
    ]
);

Search

You can now search for contacts using firstname, lastname, company, etc. (even with typos):

// search by firstname
var_dump($index->search('jimmie'));

// search a firstname with typo
var_dump($index->search('jimie'));

// search for a company
var_dump($index->search('california paint'));

// search for a firstname & company
var_dump($index->search('jimmie paint'));

Search UI

Warning: If you are building a web application, you may be more interested in using one of our frontend search UI libraries

The following example shows how to build a front-end search quickly using InstantSearch.js
