composer require ethanhann/redisearch-php

require_once 'vendor/autoload.php';

Create a Redis Client

use Ehann\RedisRaw\PredisAdapter;
use Ehann\RedisRaw\PhpRedisAdapter;
use Ehann\RedisRaw\RedisClientAdapter;

$redis = (new PredisAdapter())->connect('127.0.0.1', 6379);
// or
$redis = (new PhpRedisAdapter())->connect('127.0.0.1', 6379);
// or
$redis = (new RedisClientAdapter())->connect('127.0.0.1', 6379);

Create the Schema

use Ehann\RediSearch\Index;

$bookIndex = new Index($redis);

$bookIndex->addTextField('title')
    ->addTextField('author')
    ->addNumericField('price')
    ->addNumericField('stock')
    ->create();

Add a Document

$bookIndex->add([
    new TextField('title', 'Tale of Two Cities'),
    new TextField('author', 'Charles Dickens'),
    new NumericField('price', 9.99),
    new NumericField('stock', 231),
]);

Search the Index

$result = $bookIndex->search('two cities');

$result->getCount();     // Number of documents.
$result->getDocuments(); // Array of matches.

// Documents are returned as objects by default.
$firstResult = $result->getDocuments()[0];
$firstResult->title;
$firstResult->author;
