<div id="migration.08" class="section"><div class="info"><h1 class="title">Zend Framework 0.8</h1></div>
<p class="para">
When upgrading from a previous release to Zend Framework 0.8 or higher you
should note the following migration notes.
</p>
<div class="section" id="migration.08.zend.controller" name="migration.08.zend.controller"><div class="info"><h1 class="title">Zend_Controller</h1></div>
<p class="para">
Per previous changes, the most basic usage of the <acronym class="acronym">MVC</acronym> components
remains the same:
</p>
<div class="programlisting php"><div class="phpcode"><div class="php" style="font-family: monospace;"><ol><li style="font-family: 'Courier New', Courier, monospace; color: black; font-weight: normal; font-style: normal;"><div style="font-family: 'Courier New', Courier, monospace; font-weight: normal;">Zend_Controller_Front::<span style="color: #006600;">run</span><span style="color: #66cc66;">(</span><span style="color: #ff0000;">'/path/to/controllers'</span><span style="color: #66cc66;">)</span>;</div></li></ol></div></div></div>
<p class="para">
However, the directory structure underwent an overhaul, several
components were removed, and several others either renamed or added.
Changes include:
</p>
<ul class="itemizedlist">
<li class="listitem">
<p class="para">
<span class="classname">Zend_Controller_Router</span> was removed in favor of
the rewrite router.
</p>
</li>
<li class="listitem">
<p class="para">
<span class="classname">Zend_Controller_RewriteRouter</span> was renamed to
<span class="classname">Zend_Controller_Router_Rewrite</span>, and promoted to
the standard router shipped with the framework;
<span class="classname">Zend_Controller_Front</span> will use it by default if
no other router is supplied.
</p>
</li>
<li class="listitem">
<p class="para">
A new route class for use with the rewrite router was
introduced,
<span class="classname">Zend_Controller_Router_Route_Module</span>; it covers
the default route used by the <acronym class="acronym">MVC</acronym>, and has support for <a href="" class="link">controller
modules</a>.
</p>
</li>
<li class="listitem">
<p class="para">
<span class="classname">Zend_Controller_Router_StaticRoute</span> was renamed
to <span class="classname">Zend_Controller_Router_Route_Static</span>.
</p>
</li>
<li class="listitem">
<p class="para">
<span class="classname">Zend_Controller_Dispatcher</span> was renamed
<span class="classname">Zend_Controller_Dispatcher_Standard</span>.
</p>
</li>
<li class="listitem">
<p class="para">
<span class="methodname">Zend_Controller_Action::_forward()</span>'s arguments
have changed. The signature is now:

<p class="para">
<var class="varname">$action</var> is always required; if no controller is
specified, an action in the current controller is assumed.
<var class="varname">$module</var> is always ignored unless
<var class="varname">$controller</var> is specified. Finally, any
<var class="varname">$params</var> provided will be appended to the
request object. If you do not require the controller or
module, but still need to pass parameters, simply specify
<b><tt>NULL</tt></b> for those values.
