The <em><code class="parameter">encoding</code></em> parameter was moved from
the third position to the fourth in PHP 5.2.0. For backward
compatibility, <em><code class="parameter">encoding</code></em> can be specified
as the third parameter, but doing so is deprecated and will be
removed in the future.
