ReJSON-PHP Interface

Commanda are named after lowercase version of the original ReJSON commands.


interface ReJSON
    public function set(string $key, string $path, $json, ?string $existentialModifier = null); // $existentialModifiers: ['NX', 'XX']
    public function get(string $key, $paths = null);
    public function getArray(string $key, $paths = null);
    public function del(string $key, ?string $path = '.') : int;
    public function forget(string $key, ?string $path = '.') : int;    
    public function mget(...$keys, string $path);  
    public function mgetArray(...$keys, string $path);
    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 function arrindex(string $key, string $path, $json, ?int $start = 0, ?int $stop = 0);
    public function arrinsert(string $key, string $path, int $index, ...$jsons);
    public function arrlen(string $key, string $path = '.');
    public function arrpop(string $key, ?string $path = '.', ?int $index = -1);
    public function arrtrim(string $key, $path, ?int $start = 0, ?int $stop = 0);
    public function objkeys(string $key, ?string $path = '.');
    public function objlen(string $key, ?string $path = '.');
    public function debug(string $subcommand, ?string $key = null, ?string $path = '.');
    public function resp(string $key, ?string $paths = '.');


The recommended method to install ReJSON-PHP is with composer.

composer require mkorkmaz/redislabs-rejson


You need PECL Redis Extension or Predis to use ReJSON-PHP.

Creating ReJSON Client

Example for PECL Redis Extension

use Redis;
use Redislabs\Module\ReJSON\ReJSON;

$redisClient = new Redis();
$reJSON = ReJSON::createWithPhpRedis($redisClient);
Example for Predis

use Predis;
use Redislabs\Module\ReJSON\ReJSON;

$redisClient = new Predis\Client();
$reJSON = ReJSON::createWithPredis($redisClient);

Running commands

  • $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.

$reJSON->set('test', '.', ['foo'=>'bar'], 'NX');
$reJSON->set('test', '.baz', 'qux');
$reJSON->set('test', '.baz', 'quux', 'XX');
$reJSON->set('test2', '.', ['foo2'=>'bar2']);
$baz = $reJSON->get('test', '.baz');

// Prints string(4) "quux"
$array = $reJSON->getArray('test', '.');
Prints result as an array instead of an object
array(2) {
  string(3) "bar"
  string(4) "quux"

$array = $reJSON->mgetArray('test', 'test2', '.');
Prints result as an associative array instead of an object
array(2) {
  array(2) {
    string(3) "bar"
    string(4) "quux"
  array(1) {
    string(3) "bar2"
