What is the difference between break and continue in PHP?
BREAK:
break ends execution of the current for, foreach, while, do-while or switch structure.
CONTINUE:
continue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.
So depending on your need, you can reset the position currently being executed in your code to a different level of the current nesting.
