      Description

      Noncompliant Code Example

      if ( $a == $a ) { // always true
        doZ();
      }
      if ( $a != $a ) { // always false
        doY();
      }
      if ( $a == $b && $a == $b ) { // if the first one is true, the second one is too
        doX();
      }
      if ( $a == $b || $a == $b ) { // if the first one is true, the second one is too
        doW();
      }
      
      $j = 5 / 5; //always 1
      $k = 5 - 5; //always 0
      

      Exceptions

      Left-shifting 1 onto 1 is common in the construction of bit masks, and is ignored.

      $i = 1 << 1; // Compliant
      $j = $a << $a; // Noncompliant
