//Before xoops 2.5.8 the table 'sess_ip' was of type varchar (15). This is a problem for IPv6 addresses because it is longer. The upgrade process would change the column to VARCHAR(45) but it requires login, which is failing. If the user has an IPv6 address, it is converted to short IP during the upgrade. At the end of the upgrade IPV6 works |

PHP has two types of connecting operators (logical operators, and boolean operators):
and&&or||The difference between these is the order in which they are executed. In most cases, you would want to use a boolean operator like
&&, or||.Let’s take a look at a few examples:
Logical Operators are used for Control-Flow
One case where you explicitly want to use logical operators is for control-flow such as this:
Since
dieintroduces problems of its own, f.e. it makes our code hardly testable, and prevents any kind of more sophisticated error handling; you probably do not want to use this in real-world code. Unfortunately, logical operators cannot be combined withthrowat this point:These limitations lead to logical operators rarely being of use in current PHP code.
