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/** * Interface class for Zend_View compatible template engine implementations * * @categoryZend * @packageZend_View * @copyright Copyright （c） 2005-2011 Zend Technologies USA Inc. （http://www.zend.com） * @licensehttp://framework.zend.com/license/new-bsd 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：
