* 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.
