ARRAY_INTERSECT_KEY(3)							 1						    ARRAY_INTERSECT_KEY(3)

array_intersect_key - Computes the intersection of arrays using keys for comparison

SYNOPSIS

       array array_intersect_key (array  $array1, array  $array2, [array  $...])

DESCRIPTION

       array_intersect_key(3) returns an array containing all the entries of $array1 which have keys that are present in all the arguments.

PARAMETERS

	      o $array1
		- The array with master keys to check.

	      o $array2
		- An array to compare keys against.

	      o $...
		- A variable list of arrays to compare.

RETURN VALUES

	Returns an associative array containing all the entries of $array1 which have keys that are present in all arguments.

EXAMPLES

       Example #1

	      array_intersect_key(3) example

	      <?php
	      $array1 = array('blue'  => 1, 'red'  => 2, 'green'  => 3, 'purple' => 4);
	      $array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan'	 => 8);

	      var_dump(array_intersect_key($array1, $array2));
	      ?>

	      The above example will output:

	      array(2) {
		["blue"]=>
		int(1)
		["green"]=>
		int(3)
	      }

	In our example you see that only the keys 'blue' and 'green' are present in both arrays and thus returned. Also notice that the values for
       the keys 'blue' and 'green' differ between the two arrays. A match still occurs because only the keys are checked. The values returned  are
       those of $array1.

	The  two  keys	from  the key => value pairs are considered equal only if (string) $key1 === (string) $key2 . In other words a strict type
       check is executed so the string representation must be the same.

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" }
