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)

<?phpclass 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.rzxsoft.cn/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：
