#19073 [NEW]: isset returning false positives

From: tim@thelogichouse.com Operating system: Red Hat Linux 7.2 PHP version: 4.2.2 PHP Bug Type: Variables related Bug description: isset returning false positives $x = ""; if (isset($x)) print "X is set\n"; if (isset($y)); print "Y is set\n"; if (strlen($x) > 0) print "X is set (SL)\n"; if (strlen($y) > 0) print "Y is set (SL)\n"; ### The following script should at best print 'X is Set' because $x has been set to "". However This is my output: X is set Y is set $y is nowhere defined in the script, yet isset returns it as set. Please feel free to contact if you need any more info. Timothy M.
