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 ?
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.
