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.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;
  }
}

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"
