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)

_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;
  }
}

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"
