Pattern: Unreachable code
Issue: -
Unreachable code can never be executed because there exists no control flow path to the code from the rest of the program. It is generally considered undesirable for a number of reasons, including increased code size and increased time and effort for maintenance. Consider deleting unused code to resolve this issue.
Example of incorrect code:
switch ($number) {
case 1:
return $number . $this->ordinals['first'];
do_something(); // unreachable
break; // unreachable
case 2:
return $number . $this->ordinals['second'];
break; // unreachable
}Example of correct code:
switch ($number) {
case 1:
return $number . $this->ordinals['first'];
case 2:
return $number . $this->ordinals['second'];
}
