# Introduction

This analyzer scans your application source for any unreachable or dead code.

This analyzer is quite the wizard and detects the following situations:

  1. Unreachable statements (e.g. code after return statements).
  2. Unused methods or constants.
  3. Statements that do not do anything (no-op).

As an example of a no-op, consider the following code:



 





function exampleFn(array $a) {
    if (count($a) === 0) {
        foreach ($a as $val) {
            echo $a;
        }
    }
}

In the example code above, the highlighted line is a no-op because it is iterating over an empty array every time.
