[PHP] phpredis Hashes 데이터 타입 사용

1. Redis Hash 데이터 사용 샘플 소스

1. <?php
2. $redis = new Redis();
3. try {
4. $redis->connect('127.0.0.1', 6379, 2.5);//2.5 sec timeout
5. //Auth Password(redis.conf requirepass)
6. //$redis->auth('foobared');
7. } catch (Exception $e) {
8. exit( "Cannot connect to redis server : ".$e->getMessage() );
9. }
11. // //DB Select
12. if ( !$redis->select(0) ){
13. exit( "NOT DB Select");
14. }
16. $redis->delete('user_list');
17. $redis->hSet('user_list', 'uid1', 1);
18. $redis->hSet('user_list', 'uid2', 2);
19. $redis->hSet('user_list', 'uid3', 3);
20. if ( $redis->hExists('user_list','uid1') ){
21. echo "uid1 : ".$redis->hGet('user_list','uid1')."\n";
22. }else{
23. echo 'NOT_DATA';
24. }
25. //여러개 HASH 데이터 한번에 입력
26. $redis->hMset('user_list', array('uid4' => 4, 'uid5' =>5));
27. //여러개 HASH 데이터를 한번에 가져옴
28. var_dump($redis->hMGet('user_list', array('uid4', 'uid5')));
29. var_dump($redis->hGetAll('user_list'));
30. /*

32. uid1 : 1
33. array(2) {
34. ["uid4"]=>
