PHP 4.0 Bug #3136 Updated: switch case and unsetted variable

ID: 3136 Updated by: zeev Reported By: bago@datasail.net Status: Closed Bug Type: Misbehaving function Assigned To: Comments: This results from a change in the type of an undefined varaible. In PHP 3.0, it was an empty string. In PHP 4.0, it's a null value (i.e., not something with a definite type). If it's converted to a string, it'd still be "", but when comparing a null value with '0', PHP would consider them equivalent. Full Bug description available at: http://bugs.php.net/version4/?id=3136
