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

It is completely unclear what that means, if it wasn't thanks to a user's comment. It does ring a bell that you have to be careful when using a continue statement inside a switch statement (where in most cases it won't do what you expect) but it doesn't explain even vaguely what the behavior is and hence what you are supposed to do to avoid unexpected behavior.

One may expect that "continue" in the context of a switch statement may jump to the next case, while it seems that it will effectively be equivalent to a break inside a switch.

The note should be expanded to be clearer, and a couple of examples should be added:
- one without any loop structure outside the switch statement containing the continue statement; with no argument to continue. Which would be only a theoretical example where "continue" would be effectively equivalent to "break"
- one with a switch inside a for/while loop, first without any argument passed to continue, where the result is to only break the switch statement (most probably unwanted), and then with "continue 1" to obtain the (most probably wanted) effect of continuing the outside for loop.
