Code found after return statement
17
18 return 'hello';
19
20 return 'again'; 21 $greet = 'Hello'; 22 }
23
24 public function catch()
Description
The return keyword ends the function execution. If return is used outside of a function, it stops PHP code in the file from running.
Therefore, any code after return is considered as dead code as it won't be executed ever and can be safely removed.
Bad practice
function getSlug(string $title): string {
$array = explode(' ', strtolower($title));
return implode('-', $array);
unset($array); // invalid: this code will never executed
}
Recommended
Make sure there's no code after return statement:
function getSlug(string $title): string {
$array = explode(' ', strtolower($title));
return implode('-', $array);
}
