With PHP 7.3 a warning has been added (about an existing problem) when continue; commands are used within switch statements. Really they act as normal break; statements there and, if within a loop, we should be using continue 2; instead.

PHP Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"

This is about to find all those continue uses within switch statements and replace them with the correct statement when needed.
