note 83090 added to tutorial.useful

As an instructor of computer languages, I think your use of a double negative is a poor choice and bad example. Here is how I would code your example: <?php if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') == TRUE) { echo 'You are using Internet Explorer.<br />'; } ?> Now instead of saying something "if something is not FALSE", you are saying if "something is TRUE". Having programmed for over 30 years, I have found this much easier to code, debug and pass on to future programmers. ---- Server IP: 209.41.74.194 Probable Submitter: 192.193.221.142 ---- Manual Page -- http://www.php.net/manual/en/tutorial.useful.php Edit -- https://master.php.net/note/edit/83090 Del: integrated -- https://master.php.net/note/delete/83090/integrated Del: useless -- https://master.php.net/note/delete/83090/useless Del: bad code -- https://master.php.net/note/delete/83090/bad+code Del: spam -- https://master.php.net/note/delete/83090/spam Del: non-english -- https://master.php.net/note/delete/83090/non-english Del: in docs -- https://master.php.net/note/delete/83090/in+docs Del: other reasons-- https://master.php.net/note/delete/83090 Reject -- https://master.php.net/note/reject/83090 Search -- https://master.php.net/manage/user-notes.php
