Errors in PHP are horrible to handle. There’s absolutely no question of this RFC being revived using errors, at all. If I must, I’ll wait until exceptions are inevitably approved for core in PHP 7. Assuming they actually are. If they aren’t, I might actually quit PHP... > I would personally appreciate a syntax closer to the current casting mechanism, e.g.: > > $int = (=int) "42"; // result: (int) 42 > $string = (=string) 42; // result: (string) "42" > $int = (=int) "foobar"; // result: E_ERROR: Can not cast (string) > "foobar" strictly to an int > > $int = (~int) "42"; // result: (int) 42 > $int = (~int) "foobar"; // result: E_WARNING: Can not cast (string) > "foobar" strictly to an int PHP already already has enough bizarre syntaxes, I don’t think it needs even more. -- Andrea Faulds http://ajf.me/
