Zend Framework实现Zend_View集成Smarty模板系统的方法

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 * * @category  Zend * @package  Zend_View * @copyright Copyright (c) 2005-2011 Zend Technologies USA Inc. (http://www.zend.com) * @license  http://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);}
