Hi I noticed an little mistake in the documentation of the require_once() function.
Here you say: "Example 11-8. require_once() is case insensitive on Windows" It should be "Example 11-8. require_once() is case sensitive on Windows" (insensitive => sensitive) In fact: require_once('a_file.php'); is seen by require_once() as different from require_once('A_File.php'); even if the file is the same on Windows Thank you Michele PS: great job you guys @ php.net !!!
