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
die
introduces 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 withthrow
at this point:These limitations lead to logical operators rarely being of use in current PHP code.
