本文实例讲述了Zend Framework实现Zend_View集成Smarty模板系统的方法。分享给大家供大家参考，具体如下：
Zend_View抽象出了Zend_View_Interface，可以让我们集成不同的视图解决方案，例如可以集成smarty。要在zend中使用其他视图系统作为视图，只要实现Zend_View_Interface接口即可。
Zend_View_Interface的接口定义:
PHP;">
value pairs to set en
* masse.
*
* @see __set()
* @param string|array $spec The assignment strategy to use (key or array of key
* => value pairs)
* @param mixed $value (Optional) If assigning a named variable,use this
* as the value.
* @return void
*/
public function assign($spec,$value = null);
/**
* Clear all assigned variables
*
* Clears all variables assigned to Zend_View either via {@link assign()} or
* property overloading ({@link __get()}/{@link __set()}).
*
* @return void
*/
public function clearVars();
/**
* Processes a view script and returns the output.
*
* @param string $name The script name to process.
* @return string The script output.
*/
public function render($name);
}
集成Smarty的基本实现如下：
