如何在php Redis中对类似的键进行排序

Question

I get similar keys by using this code in php.

$cache = new Redis();
$cache->connect($this->host, $this->port);  
$allKeys = $cache->keys($key);

This is my output

Array
(
    [0] => detail_2
    [1] => detail_1
    [2] => detail_5
    [3] => detail_6
)

Here how to sort those keys, I'm using the SET method for key storage.

I tried this method for sorting $cache->sort($key), but it didn't help me.
