Description: 

All binary operators (operators that come between two values), such as +, -, =, !=, ==, >, =>, etc. need to have exactly one space before and after the operator, for readability. Alignment with extra whitespace is not allowed.

This example is now no longer allowed.

  protected $red         = array(255, 0, 0, 0);
  protected $blue        = array(0, 0, 255, 0);
  protected $orange      = array(255, 255, 0, 0);
  protected $transparent = array(0, 0, 0, 127);

This is the correct form.

  protected $red = array(255, 0, 0, 0);
  protected $blue = array(0, 0, 255, 0);
  protected $orange = array(255, 255, 0, 0);
  protected $transparent = array(0, 0, 0, 127);
