#20780 [NEW]: switch ... case ... statement cannot distinguish a string with integer 0

From: rosewell@cnk.com.cn Operating system: Windows 2000 PHP version: 4.2.3 PHP Bug Type: Scripting Engine problem Bug description: switch ... case ... statement cannot distinguish a string with integer 0 <?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 bug report at http://bugs.php.net/?id=20780&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=20780&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=20780&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=20780&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=20780&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=20780&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=20780&r=support Expected behavior: http://bugs.php.net/fix.php?id=20780&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=20780&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=20780&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=20780&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=20780&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=20780&r=dst IIS Stability: http://bugs.php.net/fix.php?id=20780&r=isapi
