RedisJSON-PHP provides a client for Redislabs' ReJSON Module for PHP. This library supports both widely used redis clients (PECL Redis Extension and Predis).
"RedisJSON is a Redis module that implements ECMA-404 The JSON Data Interchange Standard as a native data type. It allows storing, updating and fetching JSON values from Redis keys (documents)".
Commanda are named after lowercase version of the original RedisJSON commands.
<?php
use Redislabs\Interfaces\ModuleInterface;
use Predis\ClientInterface as PredisClient;
use Redis as PhpRedisClient;
interface RedisJsonInterface extends ModuleInterface
{
public function set(string $key, string $path, $json, ?string $existentialModifier = null);
public function get(...$arguments);
public function del(string $key, ?string $path = '.'): int;
public function forget(string $key, ?string $path = '.'): int;
public function mget(...$arguments);
public function type(string $key, ?string $paths = '.');
public function numincrby(string $key, string $path, int $incrementBy);
public function nummultby(string $key, string $path, int $multiplyBy);
public function strappend(string $key, $json, ?string $path = '.');
public function strlen(string $key, ?string $path = '.');
public function arrappend(string $key, string $path, ...$jsons);

public static function createWithPredis(PredisClient $client);
public static function createWithPhpRedis(PhpRedisClient $client);
}The recommended method to install RedisJSON-PHP for ReJSON is with composer.
composer require mkorkmaz/redislabs-rejsonIf you use Redis ReJSON module version 1.0:
composer require mkorkmaz/redislabs-rejson:"^1.0"You need PECL Redis Extension or Predis to use ReJSON-PHP.
<?php
declare(strict_types=1);
use Redis;
use Redislabs\Module\RedisJson\RedisJson;
$redisClient = new Redis();
$redisClient->connect('127.0.0.1');
$reJSON = ReJSON::createWithPhpRedis($redisClient);<?php
declare(strict_types=1);
use Predis;
use Redislabs\Module\RedisJson\RedisJson;
$redisClient = new Predis\Client();
$redisJson = RedisJson::createWithPredis($redisClient);- $key (or $keys - array that containes $key items) parameters are all string.
- $json (or $jsons - array that containes $json items) parameters can be any type of json encodable data (array, int, string, stdClass, any JsonSerializable object etc...).
- Commands automatically performs json encoding these data. Functions also returns json decoded data if the response is json string.
<?php
$redisJson->set('test', '.', ['foo'=>'bar'], 'NX');
$redisJson->set('test', '.baz', 'qux');
$redisJson->set('test', '.baz', 'quux', 'XX');
$redisJson->set('test2', '.', ['foo2'=>'bar2']);
$baz = $redisJson->get('test', '.baz');
var_dump($baz);
// Prints string(4) "quux"
$array = $redisJson->get('test', '.');
var_dump($array);
/*
Prints result as an array instead of an object
array(2) {
["foo"]=>
string(3) "bar"
["baz"]=>
string(4) "quux"
}
*/
$array = $redisJson->mget('test', 'test2', '.');
var_dump($array);
/*
Prints result as an associative array instead of an object
array(2) {
["test"]=>
array(2) {
["foo"]=>
string(3) "bar"
["baz"]=>
string(4) "quux"
}
["test2"]=>
array(1) {
["foo2"]=>
string(3) "bar2"
}
}
