* Less code - smaller compiled code
* Only do the test once, without the need of extra variables/...

I wonder if this should also be done on foreach:

foreach($someArray as $key => $value) {
    echo "key=$key value=$value\n";
} else {
    echo "someArray is empty";
}

$someArray could have been a function call.


Also should this happen with the alternative syntax:

while($i <= 10) :
    echo $i++;
else:
    echo "The while couldn't be executed!";
endwhile;
