Detailed explanation of Zend Framework action assistant Url usage

The example in this article describes the usage of Zend Framework action assistant Url. Share it with everyone for your reference, the details are as follows:

Url is mainly used to create 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 = $this->_helper->getHelper(&#39;UrlParser&#39;);
    //var_dump($urlParser->parse(&#39;http://www.jb51.net/article/80479.htm&#39;));
    $url = $this->_helper->getHelper(&#39;Url&#39;);
    $action = &#39;actionname&#39;;
    $controller = &#39;controllername&#39;;
    $module = &#39;modulename&#39;;
    $params = array(&#39;param1&#39;=>&#39;中文参数&#39;);
    var_dump($url->simple($action, $controller, $module, $params));
    $urlOptions = array(
        &#39;action&#39;=>$action,
        &#39;controller&#39;=>$controller,
        &#39;module&#39;=>$module,
        &#39;params&#39;=>$params);
    var_dump($url->url($urlOptions));
    var_dump($url->direct($action, $controller, $module, $params));
    exit;
  }
}
