continue not working

[Michael Satterwhite]

I *MUST* be overlooking something obvious. Consider the following code:

foreach($_POST as $key=>$value) {
print "$key=>$value<b r />";
if(! empty($value)) {
switch($key) {
case "Submit":
case "keyList":
case "curKey":
print "Matched exception<br />";
continue;
}
print "Didn't bypass.<br />";
.......

Among the form display is:

keyList=>$keyLi st
Matched exception
Didn't bypass.

Obviously, the "switch" statement was properly matched as it shows it
matched the test expression. The next statement is a "continue", which
should have gone to the next statement in the loop, but it DIDN'T. It's as
if the "continue" statement was ignored. What am I missing?

http://uk.php.net/manual/en/control-...s.continue.php

"continue

continue is used within looping structures to skip the rest of the current loop
iteration and continue execution at the beginning of the next iteration.

Note: Note that in PHP the switch statement is considered a looping
structure for the purposes of continue.

continue accepts an optional numeric argument which tells it how many levels of
enclosing loops it should skip to the end of.
"

So "continue 2" to get out of the switch and also the enclosing loop?

Thanks. While I can't think of a rational reason that a switch should be
considered a loop, there is no rule that says I have to understand it. <g>

Appreciate the help.
