[2] Podstawowe użycie Redis w PHP.

[user01@vlsr01 ~]$ mcedit use_redis.php
//utwórz nowy
<?php
$redis = new Redis();
$redis->connect("127.0.0.1",6379);
$redis->auth("TajneHasło");

//ustaw i pobierz klucz
$redis->set('key01', 'value01');
print 'key01.value : ' . $redis->get('key01') . "\n";

//dodaj i pobierz klucz
$redis->append('key01', ',value02');
print 'key01.value : ' . $redis->get('key01') . "\n";
$redis->set('key02', 1);
print 'key02.value : ' . $redis->get('key02') . "\n";

//inkrementuj
$redis->incr('key02', 100);
print 'key02.value : ' . $redis->get('key02') . "\n";

//decrementuj
$redis->decr('key02', 51);
print 'key02.value : ' . $redis->get('key02') . "\n";

//listuj
$redis->lPush('list01', 'value01');
$redis->rPush('list01', 'value02');
print 'list01.value : ';
print_r ($redis->lRange('list01', 0, -1));

//mieszaj
$redis->hSet('hash01', 'key01', 'value01');
$redis->hSet('hash01', 'key02', 'value02');
print 'hash01.value : ';
print_r ($redis->hGetAll('hash01'));

//ustaw
$redis->sAdd('set01', 'member01');
$redis->sAdd('set01', 'member02');
print 'set01.value : ';
print_r ($redis->sMembers('set01'));
?>
