Zend Framework实现Zend_View集成Smarty模板系统的方法
本文实例讲述了ZendFramework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
/**
*InterfaceclassforZend_Viewcompatibletemplateengineimplementations
*
*@categoryZend
*@packageZend_View
*@copyrightCopyright(c)2005-2011ZendTechnologiesUSAInc.(http://www.zend.com)

*/
interfaceZend_View_Interface
{
/**
*Returnthetemplateengineobject,ifany
*
*Ifusingathird-partytemplateengine,suchasSmarty,patTemplate,
*phplib,etc,returnthetemplateengineobject.Usefulforcalling
*methodsontheseobjects,suchasforsettingfilters,modifiers,etc.
*

*/
publicfunctiongetEngine();
/**
*Setthepathtofindtheviewscriptusedbyrender()
*
*@paramstring|arrayThedirectory(-ies)tosetasthepath.Notethat
*theconcreteviewimplentationmaynotnecessarilysupportmultiple

publicfunctionsetScriptPath($path);
/**

publicfunctiongetScriptPaths();

publicfunctionsetBasePath($path,$classPrefix='Zend_View');
/**

*
*@paramstring$path
*@paramstring$classPrefix
*@returnvoid
*/
publicfunctionaddBasePath($path,$classPrefix='Zend_View');
/**

*
*@paramstring$keyThevariablename.
*@parammixed$valThevariablevalue.
*@returnvoid
*/
publicfunction__set($key,$val);
/**

*

*/
publicfunction__isset($key);
/**

publicfunction__unset($key);

publicfunctionassign($spec,$value=null);
/**

publicfunctionclearVars();
/**

*

*@returnstringThescriptoutput.
*/
publicfunctionrender($name);
}
集成Smarty的基本实现如下：

/**

publicfunction__construct()

$this->smarty=$this;
if(is_callable('mb_internal_encoding')){
mb_internal_encoding(Smarty::$_CHARSET);
}

$this->debug_tpl='file:'.dirname(__FILE__).'/debug.tpl';
if(isset($_SERVER['SCRIPT_NAME'])){
$this->assignGlobal('SCRIPT_NAME',$_SERVER['SCRIPT_NAME']);
}
