Coding Style Best Practice introduced 2018-03-05 23:18 UTC by Report Bug Copy Issue Report As per coding-style, please use concatenation or `sprintf` for the variable `$codepoint` instead of interpolation. It is generally a best practice as it is often more readable to use concatenation instead of interpolation for variables inside strings. // Instead of $x = "foo $bar $baz"; // Better use either $x = "foo " . $bar . " " . $baz; $x = sprintf("foo %s %s", $bar, $baz); Loading history...

It uses sophisticated control flow analysis techniques to find statements which will never be executed. Unreachable code is most often the result of `return`, `die` or `exit` statements that have been added for debug purposes. function fx() { try { doSomething(); return true; } catch (\Exception $e) { return false; } return false; } In the above example, the last `return false` will never be executed, because a return statement has already been met in every possible execution path.
