Taking it a bit further, if the function returns a reference (eg to its
argument):
function int &myfunction(int &$param)
Alternative could be:
function &int myfunction(int &$param)
But I think that the first form is better.
From one whose job it is to daily *teach* PHP. The first form is very
much better.
And:
Suggestions to omit the word "function" altogether will be a nightmare
from a teaching point of view. Convenience for experienced programmers
should not come at the cost of unnecessary heightening of the threshold
for newcomers.
And:
Once again, the main language besides PHP for most web developers is
JavaScript. Actionscript has been mentioned. The future of Actionscript
is ES 4. And from what I've recently read JavaScript is now the most
language used of all. Anyway, here's from Brendan E:
function f(a : int, b : String, c : Object) : RetType
{
// arguments are guaranteed to match types
// return value must convert to or match RetType
}
Personally I believe that the colon adds readability. *If* return type
hints are accepted I think this syntax is the best. (I do *not* think
PHP should add anything else from ES 4 when it comes to types.)
