wincache_ucache_get — Gets a variable stored in the user cache

### Description

wincache_ucache_get(mixed `$key`, bool `&$success` = ?): mixed

Gets a variable stored in the user cache.

### 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.

`success`

  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.

The `key` is an array, the parameter `success` is always set to `true`. The returned array (name => value pairs) will 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.

### Examples

Example #1 wincache_ucache_get() with `key` as a string

`<?php
wincache_ucache_add('color', 'blue');
var_dump(wincache_ucache_get('color', $success));
var_dump($success);
?>`

The above example will output:

    string(4) "blue"
    bool(true)

Example #2 wincache_ucache_get() with `key` as an array

`<?php
$array1 = array('green' => '5', 'Blue' => '6', 'yellow' => '7', 'cyan' => '8');
wincache_ucache_set($array1);
$array2 = array('green', 'Blue', 'yellow', 'cyan');
var_dump(wincache_ucache_get($array2, $success));
var_dump($success);
?>`

The above example will output:

    array(4) { ["green"]=> string(1) "5"
               ["Blue"]=> string(1) "6"
               ["yellow"]=> string(1) "7"
               ["cyan"]=> string(1) "8" }
    bool(true)
