How get all keys in redis using php redis?

php, phpredis, redis

Solution

There is nothing wrong with your code. You are doing it correctly: `$redis->keys('*')` retrieves all the keys.

The result:

"kq92p7b5tf63tmk12v54373e03 hs7ep4lc2m6ci5kk5dosgpelg4 
pt7lfejenqbmmovjpmp9aojuf0 2p05gf20or6r5ee5i7sts90kn1 
cb1d6g3d3bvqetjfmkmaurmpp3"

is in fact the key that you set when you did:

 $redis->set(session_id(), json_encode(array('uname'=>'messi fan')));

So `session_id()` returned the value:

kq92p7b5tf63tmk12v54373e03 hs7ep4lc2m6ci5kk5dosgpelg4 
pt7lfejenqbmmovjpmp9aojuf0 2p05gf20or6r5ee5i7sts90kn1 
cb1d6g3d3bvqetjfmkmaurmpp3

therefore this became the name of the key that you set.

Problem

I am using https://github.com/nicolasff/phpredis extension to access redis. I want to get all keys in redis from PHP code. I tried following code: ``` $redis = new Redis(); $redis->connect('127.0.0.1', 6379); $allKeys = $redis->keys('*'); print_r($allKeys); // nothing here ``` But following command in shell giving results: ``` 127.0.0.1:6379> KEYS * "kq92p7b5tf63tmk12v54373e03 hs7ep4lc2m6ci5kk5dosgpelg4 pt7lfejenqbmmovjpmp9aojuf0 2p05gf20or6r5ee5i7sts90kn1 cb1d6g3d3bvqetjfmkmaurmpp3" ``` I am able to set key and data in following manner from PHP script: ``` $redis = new Redis(); $redis->connect('127.0.0.1', 6379); $redis->set(session_id(), json_encode(array('uname'=>'messi fan'))); ``` How to get `KEYS *` from redis using phpredis ?
