mget() public method

Some caches (such as memcache, apc) allow retrieving multiple cached values at the same time, which may improve the performance. In case a cache does not support this feature natively, this method will try to simulate it.
Deprecation: This method is an alias for [[multiGet()]] and will be removed in 2.1.0.
public mget ( string[] $keys ) : array
$keys string[] list of string keys identifying the cached values
return array list of cached values corresponding to the specified keys. The array is returned in terms of (key, value) pairs. If a value is not cached or expired, the corresponding array value will be false.
 /**
  * @param string[] $keys

 public function mget($keys)
 {
     return $this->cache->mget($keys);
