Yes, but changing this breaks BC unnecessarily, so we won't change it. Previous Comments: ------------------------------------------------------------------------ [2007-01-02 15:23:19] bertrand at epistema dot com Derick, thanks for reviewing this bug. After quite a lot of searching, I found the reason why: it all comes from the old "register globals" days. Obviously, a variable named $test.one would not be valid. Now, those variables are valid in a form (and in a URL), as stated here: http://www.w3.org/TR/1999/REC-html401-19991224/types.html#type-cdata Quote : ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). Therefore, one could think that since it fits in the $_POST array without problem, the underscoring of dots and spaces could only be done when registring the globals by their names, but not in the $_POST and $_GET variables. In other words, if taking the example, that could give: $test_one => 1 $test.two => 2 but also: $_POST['test.one'] => 1 $_POST['test.two'] => 2 I still consider this to be a bug, since this behaviour is *not documented* nor logical (in the case you use $_POST and $_GET variables and not register_globals, as everybody does). ------------------------------------------------------------------------ [2007-01-02 13:55:38] [EMAIL PROTECTED] Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Thank you for your interest in PHP. This has been filed many times... and it\'s not a bug. ------------------------------------------------------------------------ [2007-01-02 13:51:06] bertrand at epistema dot com Description: ------------ Can someone please add more information to bug 34578 ? The only two places in the documentation that refers to the fact that PHP replaces dots with underscores in variable names are http://fr.php.net/manual/en/language.variables.predefined.php#64336 and http://fr.php.net/manual/en/language.variables.external.php but doesn't really help on the why of this behaviour... Are dots not valid in variable names ? Since when ? Reproduce code: --------------- <?php echo '<pre>what : <br>' . print_r($_GET, true) . '</pre><br>'; ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> <form method="GET"> <input type="hidden" name="test.one" value="1" /> <input type="hidden" name="test.two" value="2" /> <input type="submit" name="submitMe" value="Click me" /> </form> </body> </html> Expected result: ---------------- Array ( [test.one] => 1 [test.two] => 2 [submitMe] => Click me ) Actual result: -------------- Array ( [test_one] => 1 [test_two] => 2 [submitMe] => Click me ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40000&edit=1
