What's the concrete advantage of switch over if-elseif? What's the concrete
advantage

Speaking specifically to your example, it does not handle multiple cases. IOW,
you cannot do this:

Hi Robert
That is impossible to implement because there's no way to tell the parser
that `switch` is statement or expression and it conflicts with `=>` in
array key expression (that's why PHP chose to have arrow function with `fn`
prefixed). And IMO your idea is harder to read than normal

If you had a really long expression, it may be easier to read if the
assignment was moved to the end, perhaps like this:

I mean separation between cases not case conditions. Examples in your RFC
uses semicolon as case separator instead of comma.
"weekend!";
case 1, 2, 3, 4, 5 => "weekday :(";
case 6 => "weekend!";
};
echo "Today is {$say}";
I prefer comma because semicolon should only be used to separate

Hi Michal
I'had the idea similar to your RFC but instead of using `switch` keyword I
think introducing `when` keyword is better. (as I know a language that uses
this keyword is Kotlin)
$result = when ($v) {
'foo' => 1,
'bar' => 2,
'x', 'y', 'z' => 3,
default => null,
};
Above
Hi David,
I'm interested in this feature this is called switch expression and is on
my list of RFC to process after Object Initializer RFC.
I have an RFC in draft for that and planning to finish it soon together
with some syntax optimisations - you can see it at
Hello. I like to suggests a discussion about a FR to make possible to
inline switch, as an alternative to nested inline conditionals.
$value = switch (expr()) {
case A1: return A2;
case B1: return B2;
default: return C;
}
Instead of:
$expr = expr();
$value = $expr == A1 ? A2 : (
15 matches
