Bug #17428 Updated: Fix the tutorial about global variables

ID: 17428 Updated by: imajes@php.net Reported By: jim.min@sivacorp.com Status: Open Bug Type: Website problem Operating System: Windows XP PHP Version: 4.2.1 New Comment: can we please stop with the Register Globals bashing? there is nothing wrong with it. We simply switch it of by default as there __could__ be security risks if users are not aware of it's awesome power. Please also do not 'fix' phpweb to not use register globals. if you must, add a comment on the show source page. Previous Comments: ------------------------------------------------------------------------ [2002-07-07 22:01:45] jacques@php.net Okay I've just done a cvs commit on tut.php which has links to the strstr manual page and the control structure page, as well as changed the variables listed to way they would be set if register_globals=off in the php.ini file. I've implemented some of philip@php.net's suggestions so far. I'll get around to going thru the entire phpweb and changing all the code to use the register_globals=off since newbies also like to view the source code to see how the webteam do various things on the site. ------------------------------------------------------------------------ [2002-07-07 21:04:04] jacques@php.net I'm currently going to fix this page now. I'm going to ensure that all the examples on the page work. Expect a commit a bit later this morning. ------------------------------------------------------------------------ [2002-07-04 21:54:27] philip@php.net This page needs a complete rewrite, this is still open. Many paragraphs are outdated and written during a time when the register_globals directive didn't even exist (always on). A simple note on the bottom that essentially says: "the above method is not preferred." isn't enough. Complete newbies read tut.php Also, superglobals becaming available in 4.1.0 should be mentioned and linked. And, all examples should work with register_globals = off. Also, for example, $HTTP_USER_AGENT is mentioned in a few places yet this isn't available with register_globals off. And lastly, tut.php needs more links to related man pages. Like the used functions and predefined variables, if statement, forms, etc. ------------------------------------------------------------------------ [2002-06-28 21:03:59] imajes@php.net fixed. ------------------------------------------------------------------------ [2002-06-20 12:39:53] philip@php.net This is a website problem (not in docs) and is rather critical as the explanations in tut.php make it sound as if register_globals is always on in PHP (like in the old days). But the example code now uses predefined vars, which is good. Although it should mention that superglobals came into existence in PHP 4.1.0 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
