Description:
------------
---
From manual page: http://www.php.net/function.preg-split#refsect1-function.preg-
split-examples
---

Examples 1&2 for the preg_split documentation page are missing the "The above 
example will output" section underneath. It's still useful to see the output 
without trying to figure out what the comment is talking about.

The output is included in the expected result section

Test script:
---------------
code examples ran:

example 1:
        $keywords = preg_split("/[\s,]+/", "hypertext language, programming");
        print_r($keywords);

example 2:
        $str      = 'string';
        $chars    = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
        print_r($chars);


Expected result:
----------------
Example 1 expected output:

Array
(
    [0] => hypertext
    [1] => language
    [2] => programming
)


example 2 expected output:

Array
(
    [0] => s
    [1] => t
    [2] => r
    [3] => i
    [4] => n
    [5] => g
)
