Logical Operators
The reason for the two different variations of "and" and "or" operators is that they operate at different precedences. (See Operator Precedence.) Example #1 Logical operators illustrated
$e = false || true;// The constant false is assigned to $f before the "or" operation occurs The above example will output something similar to: bool(true) bool(false) bool(false) bool(true) Lawrence ¶ 15 years ago
