Description:
------------
http://us2.php.net/function.array-keys

when compared with result c from example on above page, it seems that what i get is not expected result. array-keys function tests against all keys in all sub arrays!

Reproduce code:
---------------
<?php
//example array of simple website navigation structure

$array = array("about.php","contact.php","projects.php" => array("project_1.php" => array("project_1a.php","project_1b.php"),"project_2.php"));

if(in_array('project_1.php',array_keys($array)))echo 'not working as expected';
?>


Expected result:
----------------
I expect no output, but see 'not working as expected'

I am devoid of reading comprehension. The very first line in the manual said that function returns all array keys. However, example was little confusing and led me to believe the opposite.
