elseif do I need last else?

TheFinnisher

Simple question that I have always wondered about.

Is it a requirement that I have a last "else" statement in my if elseif?

or can I do:


if(something){
echo 'something';
} elseif(anotherthing){
echo 'anotherthing';
}

Do I need a final "else" condition?

Thanks!

nope, I'm sure its optional.

TheFinnisher

ok, that's what I've been doing before.

But sometimes I start doubting what I do (as I'm learning along by doing).

Thanks for confirming!

I'm still learning too, just keep in mind that if you don't insert the final else it might automatically assume ... else (the rest of the code). Unless you inserted the final else and closed it off to perform no action.

If ($a==1)
{
echo "happy";
} elseif {$a==2
echo "not happy";
} else {//do noffing}

Please correct me if I'm wrong or if someone else is able to provide a better example. Dankie

If there is no 'else', and none of the previous conditions of the if/elseif are matched, nothing is done.

$a = 10;

if($a == 3)
    echo 'Three is a good number!';
elseif($a == 13)
    echo 'Eh, that\'s not a very lucky number...';
elseif($a == 666)
    echo 'Now just who the devil are you?';

echo 'Good number!';
// end result is simply "Good number!"

Thank you brad for the much better / cleaner explanation! 😃
