It would be nice if in PHP 6 using constant parameters for functions and methods would be possible. This feature is e.g. available in Java. function doSth (const A) {
    if (defined ("A")) echo "A is a constant";
} doSth ("foo"); Cheers, Jay
This makes absolute no sense, why you want this? -- Marco It's just a way of ensuring that a parameter cannot be changed within a method (e.g. an id). I am using this feature frequently in Java. It actually got no "deeper" sense, but it's just a nice feature I'd like to use in PHP too. :-)

It actually comes from the C/C++ "const" like foo(const char *str). It makes very little sense to have it in PHP. --Pierre
