Quickstart with the PHP API client
On this page
Supported platforms
The Algolia PHP API client requires PHP version 7.2 or later.
Install
Install via Composer (recommended)
Install the package via Composer:
$
composer require algolia/algoliasearch-client-php
Install manually
- Download the client from GitHub and unzip it in your project folder.
- Inside the client root folder, run
./bin/install-dependencies-without-composer
. - In your code, require the
autoload.php
in the client root folder.
Framework integrations
Algolia officially provides support for the Laravel and Symfony frameworks.
Quickstart sample app
To download and run a self-contained example, see the PHP quickstart on GitHub.
In the following sections, you can learn how to index and search objects in 30 seconds.
Initialize the client
To start, you need to initialize the client. To do this, you need your Application ID and API Key. You can find both on your Algolia account.

// composer autoload
require __DIR__ . '/vendor/autoload.php';
// if you aren't using composer
// require_once 'path/to/algolia/folder/autoload.php';
use Algolia\AlgoliaSearch\SearchClient;
$client = SearchClient::create('YourApplicationID', 'YourWriteAPIKey');
$index = $client->initIndex('your_index_name');
The API key displayed here is your Admin API key. To maintain security, never use your Admin API key on your frontend, nor share it with anyone. In your frontend, use the search-only API key or any other key that has search-only rights.
Push data
Without any prior configuration, you can start indexing 500 contacts in the contacts
index using the following code:

$client = \Algolia\AlgoliaSearch\SearchClient::create('YourApplicationID', 'YourWriteAPIKey');
$index = $client->initIndex('contacts');
$batch = json_decode(file_get_contents('contacts.json'), true);
$index->saveObjects($batch, ['autoGenerateObjectIDIfNotExist' => true]);
Configure
You can customize settings to fine tune the search behavior. For example, you can add a custom ranking by number of followers to further enhance the built-in relevance:
1
$index->setSettings(['customRanking' => ['desc(followers)']]);
You can also configure the list of attributes you want to index by order of importance (most important first).
Algolia is designed to suggest results as you type, which means you’ll generally search by prefix. In this case, the order of attributes is crucial to decide which hit is the best.

$index->setSettings(
[
'searchableAttributes' => [
'lastname',
'firstname',
'company',
'email',
'city',
'address'
]
]
);
Search
You can now search for contacts by firstname
, lastname
, company
, etc. (even with typos):

var_dump($index->search('jimmie'));
// Search for a first name with typo
var_dump($index->search('jimie'));
// Search for a company
var_dump($index->search('california paint'));
// Search for a first name and a company
var_dump($index->search('jimmie paint'));
Search UI
If you’re building a web app, you may be interested in using one of Algolias frontend search UI libraries.
