wincache_ucache_get - Gets a variable stored in the user cache

SYNOPSIS

       mixed wincache_ucache_get (mixed  $key, [bool  &$success])

DESCRIPTION

	Gets a variable stored in the user cache.

PARAMETERS

	      o $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.

	      o $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(3) 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(3) 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)
