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 /** * Interface class for Zend_View compatible template engine implementations * * @category Zend * @package Zend_View * @copyright Copyright (c) 2005-2011 Zend Technologies USA Inc. () * @license New BSD License */ interface Zend_View_Interface { /** * Return the template engine object, if any * * If using a third-party template engine, such as Smarty, patTemplate, * phplib, etc, return the template engine object. Useful for calling * methods on these objects, such as for setting filters, modifiers, etc. * * @return mixed */ public function getEngine(); /** * Set the path to find the view script used by render() * * @param string|array The directory (-ies) to set as the path. Note that * the concrete view implentation may not necessarily support multiple * directories. * @return void */ public function setScriptPath($path); /** * Retrieve all view script paths * * @return array */ public function getScriptPaths(); /** * Set a base path to all view resources * * @param string $path * @param string $classPrefix * @return void */ public function setBasePath($path, $classPrefix = 'Zend_View'); /** * Add an additional path to view resources * * @param string $path * @param string $classPrefix * @return void */ public function addBasePath($path, $classPrefix = 'Zend_View'); /** * Assign a variable to the view * * @param string $key The variable name. * @param mixed $val The variable value. * @return void */ public function __set($key, $val); /** * Allows testing with empty() and isset() to work * * @param string $key * @return boolean */ public function __isset($key); /** * Allows unset() on object properties to work * * @param string $key * @return void */ public function __unset($key); /** * Assign variables to the view script via differing strategies. * * Suggested implementation is to allow setting a specific key to the * specified value, OR passing an array of key => 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：
