Hi again guys....
I would just like to hear you oppinions about something like
this...(please don't shoot me :) )
ex1:
function AddToDb(mysql_scape_string($text)) {
//enter $text to db
}
which would be the same as
function AddToDb($text) {
$text = mysql_escape_string($text);
//enter $text to db
}
or
ex2:
function removeDigitsFromText($text) {
//return the text striped from digits
}
function AddTextToDB(removeDigitsFromText($text)) {
//add text to db;
}
This could be very usefull although I do understand that it could cause
problems (references for example) ....
I know this concept looks a bit strange but just wanted to hear
oppinions from the experts... :)
Thanx
Ante

Why could this be usefull? You're putting logic into the parameter list, I can't
think of a reason why you would like to do this.

This could never be useful. Trying to condense as much code as you can
down to as few lines as possible doesn't actually speed up the
execution, nor does it make it more readable.
Having logic in the parameter list removes the possibility of properly
documenting it and would be executed no quicker than having it done
separately.
If you're developing a public API as it seems you are, then the need for
proper documentation far outweighs the need to condense all the code
down, even for processes that are as obvious as escaping a string.
In short, there's no good reason for this to exist in any language (as
far as I can see) and would probably add more overhead to the processing
of parameter lists.

This concept looks strange (and non-standard - do any other languages
support this semantic?). It doesn't save you much typing either.

I'd say it's not too useful but opens up a can of worms:
- You're adding code to a declaration, IMHO confusing
- How complicated code is allowed, e.g. what happens with
function foo(bar($p1, $p2)) {
or
function foo($p2->bar($p1), $p1->bar($p2)) {
I think we should keep the language simple and stay with
$text = mysql_scape_string($text);
at the beginning of the function. That way everybody understands what's
going on.
