update: added additional note fields (#29551)

* fix: corrected placement of notes

Some "note" fields were preemptive in their placement; I corrected their placement to be in more appropriate locations.

* update: added additional note fields

Added some additional "note" fields to assist those who are reading through the PHP documentation.

* fix: formatting of escape sequence examples

The formatting was a bit jumbled, so I cleaned up the formatting of the escape sequence.

* update: improved examples

I added a new example to demonstrate the use of a "break" statement in a while loop, as well as numbered each example.

* update: add clarifying statement

I added a note at the end of the description, with the goal of being a bit more explicit in terms of what the "continue" statement does.
