There is nothing wrong with your code. You are doing it correctly: $redis->keys('*')retrieves all the keys.
您的代码没有任何问题。您做得对：$redis->keys('*')检索所有密钥。
The result:
结果：
"kq92p7b5tf63tmk12v54373e03 hs7ep4lc2m6ci5kk5dosgpelg4
pt7lfejenqbmmovjpmp9aojuf0 2p05gf20or6r5ee5i7sts90kn1
cb1d6g3d3bvqetjfmkmaurmpp3"
is in fact the key that you set when you did:
实际上是您在执行时设置的键：
$redis->set(session_id(), json_encode(array('uname'=>'messi fan')));
So session_id()returned the value:
所以session_id()返回值：
kq92p7b5tf63tmk12v54373e03 hs7ep4lc2m6ci5kk5dosgpelg4
pt7lfejenqbmmovjpmp9aojuf0 2p05gf20or6r5ee5i7sts90kn1
cb1d6g3d3bvqetjfmkmaurmpp3
therefore this became the name of the key that you set.
因此这成为您设置的密钥的名称。

$redis = new Redis();
$redis->connect('xxxxxx', 6379); // use your Host from Redis desktop Manager - connection
$redis->auth('xxxxxx'); // use your Auth from Redis desktop Manager - connection
$allKeys = $redis->keys('*');
print_r($allKeys); // nothing here
