Using a while statement in an echo.

Yeah, and with Dan, years.. and he is still doing it.

It's even recommended on the PHP.net site, that you don't use ()'s with language constructs, as it gives PHP more work to do.

It was suggested that using ()'s with language constructs be removed in 6.0, and is still an undecided issue.

What, where are you getting this information, using parenthesis doesn't make it do any extra work at all.

Note: Note that since return() is a language construct and not a function, the parentheses surrounding its arguments are not required. It is common to leave them out, and you actually should do so as PHP has less work to do in this case.

Note: You should never use parentheses around your return variable when returning by reference, as this will not work. You can only return variables by reference, not the result of a statement. If you use return ($a); then you're not returning a variable, but the result of the expression ($a) (which is, of course, the value of $a).

Did you not see the part where it says "in this case" and where I say "I don't use parenthesis on return"???

Yeah, it's for echo too.. I can't find it tonight.

Either way the core still has to process it like a function, and it has it's limitations, and slows it down by a moderate degree.

I don't think so

Read up on how the core actually works, you'll see how it goes at parsing languages constructs, using ()'s does give it more work.. because it has to sort through them, plus make sure not more then one variable is in it.
