I’ve been looking through Zend Framework’s source code and noticed that most (if not all) comparisons are done with the operands in the reverse order I would expect:
if ((false !== $request) {
...
}
instead of:
if (($request !== false) {
...
}
What is the reason for this convention?
It’s called a
Left-Hand Comparison.Basically, it’s so that if you forget to put the second
=in==, it’ll error rather change the value of the variable…
