I know I can just cast to int, but is it ok to return an string for
things that can only be numbers?


<?php
// imagine today is sunday
var_export(date('w') === 0);
?>

prints false, but I expected it to return an int. Am I wrong? I imagine
it's the same thing with the rest of date's return values.


Btw, I don't hope it will be changed because it would probably break a
lot of scripts.

<manual>
string date ( string format [, int timestamp])
</manual>

Looks like it returns a string.

you've been hearing about.  No, sir.  Our model is the trapezoid!

The date() and strftime() functions are expected to always return
strings, no matter what the format string looks like.
The same holds true for sprintf(), you wouldn't expect

sprintf("%d", 42)

to return an int, would you?

I think I just smoked something illegal before posting that question.
The brain damage seems to be gone, sorry for the spam. It just did made
sense at that moment.
