Mastering PHP 7

Inserting

The simplicity behind the Redis key-value mechanism makes for a simple and straightforward set() method, through which we insert new entries, as shown in the following example:

<?phptry {    $client = new Redis();    $client->connect('localhost', 6379);    $client->set('user', [        'name' => 'John',        'age' => 34,        'salary' => 4200.00    ]);    // $client->get('user');    // returns string containing "Array" chars    $client->set('customer', json_encode([        'name' => 'Marc',        'age' => 43,        'salary' => 3600.00    ]));    // $client->get('customer');    // returns json looking string, which we can simply json_decode()} catch (RedisException $e) {    echo $e->getMessage(), PHP_EOL;}

This should give us the following output:

We should be careful when using the set methods ...
