The following functions are available:
-element()
-=========
-.. function:: element($item, $array, $default = NULL)
+.. function:: element($item, $array[, $default = NULL])
:param string $item: Item to fetch from the array
:param array $array: Input array
:param bool $default: What to return if the array isn't valid
:returns: NULL on failure or the array item.
-Lets you fetch an item from an array. The function tests whether the
-array index is set and whether it has a value. If a value exists it is
-returned. If a value does not exist it returns NULL, or whatever you've
-specified as the default value via the third parameter.

-Lets you fetch a number of items from an array. The function tests
-whether each of the array indices is set. If an index does not exist it
-is set to NULL, or whatever you've specified as the default value via
-the third parameter.
