Triple equal operator fails when checking for one of variants but they are the same type

Question

$type = 'bravo';

if ($type === ('alpha' || 'bravo')) {
    echo $type;
}

This never returns anything. Why this is happening?

Answer 1

Try this:

if ($type === 'alpha' || $type === 'bravo') {
    echo $type;
}

You have to check values individually.

Answer 2

'alpha' || 'bravo' is boolean true not string 'bravo'
