Yaf_View_Simple::assignRef — The assignRef purpose

### 说明

public function Yaf_View_Simple::assignRef(string `$name`, mixed `&$value`): bool

不同于 Yaf_View_Simple::assign()，这个方法传递一个引用变量给模板引擎。

### 参数

`name`

  字符串名，被用来传递值给模板。

`value`

  混合值

### 返回值

### 示例

示例 #1 Yaf_View_Simple::assignRef() 示例

    <?php
    class IndexController extends Yaf_Controller_Abstract {
        public function indexAction() {
            $value = "bar";
            $this->getView()->assign("foo", $value);

            /* plz note that there was a bug before Yaf 2.1.4,
             * which make following output "bar";
             */
            $dummy = $this->getView()->render("index/index.phtml");
            echo $value;

            //prevent the auto-render
            Yaf_Dispatcher::getInstance()->autoRender(FALSE);
        }
    }
    ?>

示例 #2 Template 示例

    <html>
     <head>
      <title><?php echo $foo;  $foo = "changed"; ?></title>
     </head>
    <body>
    </body>
    </html>

以上示例的输出类似于：

    /* access the index controller will result: */
    changed
