New Comment:
I think that Mr Jesus Catagnetto misunsterstood what I am talking
about. IMO the bug must be reopened.
I just wanted to say that
while (some){
switch ($foo){
case 'bar':
if (some_reason) continue;//ie next iteration, but no, it will
increment counter after the switch. Must be continue(2);
break;
case 'boo':
//
break;
default:
break;
}
echo $counter++;
}

Ehem, the documentation for "switch" explicitly says:
"... The switch statement is similar to a series of IF statements on
the same expression ..."
And I do not know of any language that uses a series of if statements
as a loop construct (that is why for, while and do ... while are
there). If you know of one, I will be interesting to check it out to
see how that can be done.
Also, nowhere there is mentioned that "continue" can be used to loop in
a non-looping construct (e.g. if), and if you read again the the
description of "continue" it says:
"continue is used within looping structures to skip the rest of the
current loop iteration and continue executio at the beginning of the
next iteration"
thus if you use that in a context where there is no loop, it just gets
out of scope.
This is (or should) something learned in basics of programming book,
article, etc.

After 2 years of coding in PHP I found something strange to me but
probably not to the creators of PHP :)). continue; inside a switch
statement is equivalent of break; For this reason I've found 3 closed
bugs - 5805, 8768 & 7591. However there is no info in the docs that
switch() is one time loop - as said in one of the answer of one of the
reports. I think that switch() docs has to mention that switch() is
works like one iteration loop and that continue without any params
within a switch is equivalent of break;. Thus the effect which one may
want will be continue (level+1) (level is the level which will be if
the program was written in C). Finally there should be short note in
the continue; docs that inside a switch() it works somekind different
than in C and provided link to switch() page for more info.
Best regards,
