        Why is this an issue?

        A value that is incremented or decremented and then not stored is at best wasted code and at worst a bug.

        Noncompliant code example

          $i = 0;
          $i = $i++; // Noncompliant; i is still zero
        

        Compliant solution

          $i = 0;
          $i++;
