Parameters
-
key

The key that was used to store the variable in the cache.
key is case sensitive. key can be an
array of keys. In this case the return value will be an array of values of each element
in the key array. If an object, or an array containing objects,
is returned, then the objects will be unserialized. See
__wakeup() for details on unserializing objects.

Will be set to true on success and false on failure.
Return Values
If key is a string, the function returns the value of the variable stored with that key.
The success is set to true on success and
to false on failure.

contain only those name => value pairs for which the get operation in user cache was
successful. If none of the keys in the key array finds a match in the user cache
an empty array will be returned.

Example #2 wincache_ucache_get with key as an array

$array2 = array('green', 'Blue', 'yellow', 'cyan');
var_dump(wincache_ucache_get($array2, $success));
var_dump($success);
?>
The above example will output:
