本文实例讲述了Zend Framework动作助手Url用法。分享给大家供大家参考，具体如下：

Url主要用于创建url；

public function simple($action, $controller = null, $module = null, array $params = null)
public function url($urlOptions = array(), $name = null, $reset = false, $encode = true)
public function direct($action, $controller = null, $module = null, array $params = null)

<?php
class IndexController extends Zend_Controller_Action
{
 public function init()
 {
 /* Initialize action controller here */
 }
 public function indexAction()
 {
 //$urlParser = $this->_helper->getHelper('UrlParser');
 //var_dump($urlParser->parse('//www.jb51.net/article/80479.htm'));
 $url = $this->_helper->getHelper('Url');
 $action = 'actionname';
 $controller = 'controllername';
 $module = 'modulename';
 $params = array('param1'=>'中文参数');
 var_dump($url->simple($action, $controller, $module, $params));
 $urlOptions = array(
 'action'=>$action,
 'controller'=>$controller,
 'module'=>$module,
 'params'=>$params);
 var_dump($url->url($urlOptions));
 var_dump($url->direct($action, $controller, $module, $params));
 exit;
 }
}

string(101) "/helper_demo1/public/modulename/controllername/actionname/param1/%E4%B8%AD%E6%96%87%E5%8F%82%E6%95%B0" string(101) "/helper_demo1/public/modulename/controllername/actionname/params/%E4%B8%AD%E6%96%87%E5%8F%82%E6%95%B0" string(101) "/helper_demo1/public/modulename/controllername/actionname/param1/%E4%B8%AD%E6%96%87%E5%8F%82%E6%95%B0"
