title: PHP Line Indentation
body: <p>I'm curious to know, how many spaces of indentation do you prefer in PHP code?</p>
  
  <pre><code>function one()
  {
   $one;
   function space()
   {
    $space;
   }
  }
  
  function two()
  {
    $two;
    function spaces()
    {
      $spaces;
    }
  }
  
  function three()
  {
     $three;
     function spaces()
     {
        $spaces;
     }
  }
  
  function four()
  {
      $four;
      function spaces()
      {
          $spaces;
      }
  }
  </code></pre>
  
  <p>Let's not make multiple answers for same indentation, but use the +1 for answers that fit your preferences.</p>
