SYNOPSIS

       bool wincache_ucache_delete (mixed  $key)

DESCRIPTION

	Deletes the elements in the user cache pointed by $key.

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.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	If  $key  is  an  array  then the function returns FALSE if every element of the array fails to get deleted from the user cache, otherwise
       returns an array which consists of all the keys that are deleted.

EXAMPLES

       Example #1

	      Using wincache_ucache_delete(3) with $key as a string

	      <?php
	      wincache_ucache_set('foo', 'bar');
	      var_dump(wincache_ucache_delete('foo'));
	      var_dump(wincache_ucache_exists('foo'));
	      ?>

	      The above example will output:

	      bool(true)
	      bool(false)

       Example #2

	      Usingwincache_ucache_delete(3) with $key as an array

	      <?php
	      $array1 = array('green' => '5', 'blue' => '6', 'yellow' => '7', 'cyan' => '8');
	      wincache_ucache_set($array1);
	      $array2 = array('green', 'blue', 'yellow', 'cyan');
	      var_dump(wincache_ucache_delete($array2));
	      ?>

	      The above example will output:

	      array(4) { [0]=> string(5) "green"
			 [1]=> string(4) "Blue"
			 [2]=> string(6) "yellow"
			 [3]=> string(4) "cyan" }

       Example #3

	      Using wincache_ucache_delete(3) with $key as an array where some elements cannot be deleted

	      <?php
	      $array1 = array('green' => '5', 'blue' => '6', 'yellow' => '7', 'cyan' => '8');
	      wincache_ucache_set($array1);
	      $array2 = array('orange', 'red', 'yellow', 'cyan');
	      var_dump(wincache_ucache_delete($array2));
	      ?>

	      The above example will output:

	      array(2) { [0]=> string(6) "yellow"
			 [1]=> string(4) "cyan" }

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)
