zend中怎样接受post过来的数组

从页面上post过来一个数组，我在action中怎么接收那？

$_POST

$_POST最直接了。

也可以在Controller中使用       
$this->getRequest()->getParam('postme');

相当于访问$_REQUEST。

getParam() retrieves more than user params

In order to do some of its work, getParam() actually retrieves from several sources. In order of priority, these include: user parameters set via setParam(), GET parameters, POST parameters, and finally COOKIE parameters. Be aware of this when pulling data via this method.
