I'm replying to you *and* to the list, in case the information

Well, my first question is: what happens when you try it?
Inside a switch(), a continue works exactly the same as a break, *as
long as it has no arguments*. Numeric arguments to continue then apply
to any containing looping structures--treating the switch() as the
first.
For more information on continue, and its optional arguments, see
http://www.php.net/continue. For a simple test case, try the following
test script and compare it to the expected output.
---script---
<?php
error_reporting(E_ALL);
$case = 'bar';
switch ($case) {
case 'foo':
echo "foo\n";
break;
case 'bar':
echo "bar\n";
continue;
default:
echo "default\n";
}
for ($i = 0; $i < 10; $i++) {
echo "Start of for() loop; item $i: ";
switch ($i) {
case 1:
echo "$i: foo\n";
continue 2;
case 2:
echo "$i: bar\n";
continue 2;
default:
echo "$i: default\n";
}
echo "End of for() loop\n";
}
?>
---output---
bar
Start of for() loop; item 0: 0: default
End of for() loop
Start of for() loop; item 1: 1: foo
Start of for() loop; item 2: 2: bar
Start of for() loop; item 3: 3: default
End of for() loop
Start of for() loop; item 4: 4: default
End of for() loop
Start of for() loop; item 5: 5: default
End of for() loop
Start of for() loop; item 6: 6: default
End of for() loop
Start of for() loop; item 7: 7: default
End of for() loop
Start of for() loop; item 8: 8: default
End of for() loop
Start of for() loop; item 9: 9: default
End of for() loop
Hope this helps,
