ID: 20780 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Bogus Bug Type: Scripting Engine problem Operating System: Windows 2000 PHP Version: 4.2.3 New Comment:
Thanks a lot for your tip. And now I've seen what a silly mistake I'd made. And I felt deeply sorry for disturbing you with such a silly fault. But I wonder if PHP can introduce a Not_a_Number value just like the NaN in JavaScript. For PHP and JavaScript are both loose-type language, i.e. scripting language. For some convention, I think, it is unusual to automatically convert a string (especially a NOT_A_NUMBER string) to an integer, in which most case is converted to 0 and is not intuitionistic. And I find many people before have complained about it. So I'll be glad that you'll consider it. Thank you again for your serious consideration.

Thank you for your interest in PHP. See http://ch.php.net/manual/en/language.types.string.php#language.types.string.conversion ------------------------------------------------------------------------ [2002-12-02 23:54:45] [EMAIL PROTECTED] <?php $a = 'center'; switch ($a) { case 'left': case 0: echo 'left';break; case 'right': case 2: echo 'right';break; default:echo 'center'; } ?> The script should generate 'center',yet generate 'left';what's more,any string assigned to variable $a will generate the same error. The reason is the PHP scripting engine cannot distinguish a string with integer 0. I wonder if the switch statement can only be applied on integers. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20780&edit=1
