I understand that variable names can't have '.' or ' ' in them, however it seems that most people use the $_POST['variablename'] method of accessing external variables, and in this case, the spaces and dots make no difference. I could find practically no reference to this behavior in the manual, other than a couple notes I submitted. At the very least, the fact that these characters are replaced should be made more obvious in the manual under "Predefined Variables" at http://us2.php.net/manual/en/language.variables.predefined.php and http://us2.php.net/manual/en/reserved.variables.php Reproduce code: --------------- <form method="post"> <input name="title for page3.php" type="text"> <input type="submit"> </form> Title submitted: <?php if (count($_POST) > 0) echo $_POST['title for page3.php']; ?> Expected result: ---------------- I expect to see the title I submitted print out. Actual result: -------------- The POST key 'title for page3.php' is changed to 'title_for_page3_php', and nothing prints out. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40224&edit=1
