EACH(3) 								 1								   EACH(3)

each - Return the current key and value pair from an array and advance the array cursor

SYNOPSIS

       array each (array  &$array)

DESCRIPTION

	Return the current key and value pair from an array and advance the array cursor.

	After each(3) has executed, the array cursor will be left on the next element of the array, or past the last element if it hits the end of
       the array. You have to use reset(3) if you want to traverse the array again using each.

PARAMETERS

	      o $array
		- The input array.

RETURN VALUES

	Returns the current key and value pair from the array $array. This pair is returned in a four-element array, with the keys 0, 1, key,  and
       value. Elements 0 and key contain the key name of the array element, and 1 and value contain the data.

	If the internal pointer for the array points past the end of the array contents, each(3) returns FALSE.

EXAMPLES

       Example #1

	      each(3) examples

	      <?php
	      $foo = array("bob", "fred", "jussi", "jouni", "egon", "marliese");
	      $bar = each($foo);
	      print_r($bar);
	      ?>

	      $bar now contains the following key/value pairs:

	      Array
	      (
		  [1] => bob
		  [value] => bob
		  [0] => 0
		  [key] => 0
	      )

       <?php
       $foo = array("Robert" => "Bob", "Seppo" => "Sepi");
       $bar = each($foo);
       print_r($bar);
       ?>

       $bar now contains the following key/value pairs:

       Array
       (
	   [1] => Bob
	   [value] => Bob
	   [0] => Robert
	   [key] => Robert
       )

       each(3) is typically used in conjunction with list(3) to traverse an array, here's an example:

       Example #2

	      Traversing an array with each(3)

	      <?php
	      $fruit = array('a' => 'apple', 'b' => 'banana', 'c' => 'cranberry');

	      reset($fruit);
	      while (list($key, $val) = each($fruit)) {
		  echo "$key => $val
";
	      }
	      ?>

	      The above example will output:

	      a => apple
	      b => banana
	      c => cranberry

       Caution

	       Because	assigning  an array to another variable resets the original array's pointer, our example above would cause an endless loop
	      had we assigned $fruit to another variable inside the loop.

       Warning

	      each(3) will also accept objects, but may return unexpected results. It's therefore not recommended to iterate though object proper-
	      ties with each(3).

WINCACHE_UCACHE_DELETE(3)						 1						 WINCACHE_UCACHE_DELETE(3)

wincache_ucache_delete - Deletes variables from the user cache

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" }
