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('//www.zwyuanma.com/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;

  }

}







www.localzend.com/helper_demo1/public/index

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：
