From: Nico dot Laus dot 2002 at gmx dot de Operating system: WinXP SP1 PHP version: 5CVS-2003-07-01 (dev) PHP Bug Type: Class/Object related Bug description: isset() and empty() produce errors with non-existent variables in classes Description: ------------ When checking variables either not declared or after having unset() them with empty() or isset(), some errors occure. In former times, empty() and isset() have not produced errors - even if it is a NOTICE now. -> hopefully this is not the way it is meant to be - I think, than it's not only me who has to rewrite his code Reproduce code: --------------- class test { function __construct() { if (empty($this->test[0][0])) { print "test1";} if (!isset($this->test[0][0])) { print "test2";} } } $test1 = new test(); Expected result: ---------------- test1test2 Actual result: -------------- Notice: Undefined property: test::$test in D:\inetpub\wwwroot\fmwars\temp.php on line 41 test1Notice: Undefined property: test::$test in D:\inetpub\wwwroot\fmwars\temp.php on line 42 test2 -- Edit bug report at http://bugs.php.net/?id=24436&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=24436&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=24436&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=24436&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=24436&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=24436&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=24436&r=support Expected behavior: http://bugs.php.net/fix.php?id=24436&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=24436&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=24436&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=24436&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=24436&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=24436&r=dst IIS Stability: http://bugs.php.net/fix.php?id=24436&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=24436&r=gnused
