Zend Framework动作助手Url用法详解

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('http://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"

实现源码如下：

    require_once 'Zend/Controller/Action/Helper/Abstract.php';
    /**
