PHP has pseudo-functions, maybe we could use that format? cast_int($foo)?Actually, perhaps the solution is an ahead-of-time check: if (safe_cast($foo, int)) { $bar = (int!)$foo; } else { $bar = 1; }
I think this would be quite nice - keeps things relatively short without introducing so much punctuation that it starts looking like a Perl script ;)
The only problem is that either you need a whole set of functions (safe_int($foo), safe_float($foo), etc) or you need some format for that second argument, which gets you into some odd meta-validation: if you take a string, or an integer (expected to be in the form of a constant like PHP_INT), then it would be possible to write safe_cast($foo, $bar), and now we need rules on validating $bar, and what happens if it's wrong.
The magic form with a keyword like you've written avoids that, but it feels kind of weird - like when SQL date functions take things like "day" and "hour" as barewords rather than strings.
Maybe I'm overthinking it though. -- Rowan Collins [IMSoP] -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
