最近折腾了框架的性能测试,其中需要测试各个模板跟smarty配合的性能,所以折腾了一桶,现总结一下。之前已经写过kohana框架+smaryt模板,这里不再重复了。

一,yii框架+smarty模板

        yii是覆盖了viewRenderer组件。

1.1,下载yii框架并解压,下载smarty框架并解压,将smarty/libs文件夹拷到yii框架application/protected/vendors下面,并重命名smarty。

1.2,yii配置文件main.php

'components'=>array(      'viewRenderer' => array(          'class'=>'batman.protected.extensions.SmartyViewRender',          // 这里为Smarty支持的属性          'config' => array (                  'left_delimiter' => "{#",                  'right_delimiter' => "#}",                  'template_dir' => APP_DIR . "/views/",                  'config_dir' => APP_DIR . "/views/conf/",                  'debugging' => false,                  'compile_dir' => 'D:/temp/runtime',            )       )  

其中batman是我已经在index.php定义好的别名。

Yii::setPathOfAlias('batman', dirname(__FILE__));Yii::import("batman.protected.vendors.*");define('APP_DIR', dirname(__FILE__).'/protected/');

1.3,在protected/extensions/下面新建SmartyViewRender.php

<?phpclass SmartyViewRender extends CApplicationComponent implements IViewRenderer {public $fileExtension = '.html';private $_smarty = null;public $config = array();public function init() {$smartyPath = Yii::getPathOfAlias('batman.protected.vendors.smarty');        Yii::$classMap['Smarty'] = $smartyPath . '/Smarty.class.php';        Yii::$classMap['Smarty_Internal_Data'] = $smartyPath . '/sysplugins/smarty_internal_data.php';        $this->_smarty = new Smarty();        // configure smartyif (is_array ( $this->config )) {foreach ( $this->config as $key => $value ) {if ($key {0} != '_') { // not setting semi-private properties$this->_smarty->$key = $value;}}}        Yii::registerAutoloader('smartyAutoload');}public function renderFile($context, $file, $data, $return) { foreach ($data as $key => $value)                $this->_smarty->assign($key, $value);        $return = $this->_smarty->fetch($file);        if ($return)                return $return;        else                echo $return;}}

1.4,验证

新建一个HelloController.php

<?phpclass HelloController extends Controller {public function actionWorld() {$this->render('world', array('content'=>'hello world'));}}

新建一个word.html

<body>{#$content#}</body>



二,CI框架+smarty模板

        网上很多方法,将smarty作为一个普通的library,在使用的时候,controller代码类似于下面:

        public function index()          {                  $this->load->library('smarty/Ci_smarty', '', 'smarty');                  $this->smarty->assign("title","恭喜你smarty安装成功!");                  $this->smarty->assign("body","欢迎使用smarty模板引擎");                  $arr = array(1=>'zhang',2=>'xing',3=>'wang');                  $this->smarty->assign("myarray",$arr);                  $this->smarty->display('index_2.html');          }  

这种方法跟CI自带的使用模板的方法

$this->load->view();
不和谐,而且要一系列的
$this->smarty->assign();

语句,麻烦不说,还破坏了原本CI的简洁美,所以果断唾弃之。

        那怎么保持CI加载view时的简洁美呢,答案就是覆盖Loader类的view()方法。好吧,let's begin。

2.1,条件:

        到官网上现在CI框架和smarty模板。

2.2,确保CI已经能跑起来

        将CI框架解压到网站跟目录下,先写一个不带smarty模板的controller输出“hello world”。

2.3,引入smarty

        将smarty解压,将libs文件夹考到application/third_paty下面,并将libs重命名smarty,重命名取什么都ok了,这里就叫smarty吧。

2.4,覆盖loader类的view()方法

        因为view()方法在Loader类里,所以我要覆盖Loader的view()方法。

        先看看$this->load->view()是怎么工作的?CI_Controller类的构造函数里有这么一行

$this->load =& load_class('Loader', 'core');

load_class函数会先在application/core下面找config_item('subclass_prefix').Loader.php文件,找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在配置文件里写的你要继承CI核心类的子类的前缀。我使用的是默认值'MY_'。找到文件后,require该文件,然后new  MY_Loader(如果application/core/MY_Loader.php存在),或者是new Loader,赋值给$this->load。

        在application/core下面新建一个MY_Loader.php文件

<?phpdefine('DS', DIRECTORY_SEPARATOR);class MY_Loader extends CI_Loader {public $smarty;public function __construct() {parent::__construct();require APPPATH.'third_party'.DS.'smarty'.DS.'smarty.class.php';$this->smarty = new Smarty ();// smarty 配置$this->smarty->template_dir=   APPPATH.'views'.DS;//smarty模板文件指向ci的views文件夹  $this->smarty->compile_dir  =   'd:/temp/tpl_c/';  $this->smarty->config_dir    =   APPPATH.'libraries/smarty/configs/';  $this->smarty->cache_dir     =   'd:/temp/cache';  $this->smarty->left_delimiter = '{#';$this->smarty->right_delimiter = '#}'; }public function view($view, $vars = array(), $return = FALSE){// check if view file exists$view .= config_item('templates_ext');$file = APPPATH.'views'.DS.$view;if (! file_exists ( $file ) || realpath ( $file ) === false) {exit( __FILE__.' '.__LINE__."<br/>View file {$file} does not exist, <br/>{$file} => {$view}");}// changed by simeng in order to use smarty debugforeach ( $vars as $key => $value ) {$this->smarty->assign ( $key, $value );}// render or returnif ($return) {ob_start ();}$this->smarty->display ( $view );if ($return) {$res = ob_get_contents ();ob_end_clean ();return $res;}}}
我把template_ext配置成了".html",这样就ok了。我们来验证一下吧。

2.5,验证

        在controller下面建一个home.php

class Home extends CI_Controller {  public function index() {        $data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');$data['title'] = "恭喜你smarty安装成功!";$data['body'] = "欢迎使用smarty模板引";$arr = array(1=>'zhang',2=>'xing',3=>'wang'); $data['myarray'] = $arr;$this->load->view('index_2', $data);    }} 
        在views下面建一个index_2.html

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">      <html xmlns="http://www.w3.org/1999/xhtml">      <head>       <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />       <script src='<!--{$base_url}-->js/jquery.min.js' type='text/javascript' ></script>       <link href="<!--{$base_url}-->css/login.css" rel="stylesheet" type="text/css" />       <title>smarty安装测试</title>      </head>      <body>      <h1>{#$title#}</h1>      <p>{#$body#}</p>      <ul>              {#foreach from=$myarray item=v#}              <li>{#$v#}</li>             {#/foreach#}      </ul>      </body>      </html>  

好了,可以试试你的成果了。


三,yaf框架+smarty模板

yaf是利用引导文件Bootstrap.php来加载smarty。

3.1,使用Bootstrap

        在index.php中用

$app->bootstrap()->run();

引入Bootstrap.php文件

3.2,在application/Bootstrap.php文件中导入smarty。

<?phpclass Bootstrap extends Yaf_Bootstrap_Abstract {    public function _initSmarty(Yaf_Dispatcher $dispatcher) {        $smarty = new Smarty_Adapter(null, Yaf_Application::app()->getConfig()->smarty);        Yaf_Dispatcher::getInstance()->setView($smarty);    }}
3.3,添加Smarty_Adapter类

        将smarty解压后放到application/library文件夹下,重命名为Smarty。在Smarty下新建Adapter.php,确保Smarty.class.php在Smarty/libs/下。Adapter.php内容:

<?phpYaf_Loader::import( "Smarty/libs/Smarty.class.php");Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_templatecompilerbase.php");Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_templatelexer.php");Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_templateparser.php");Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_compilebase.php");Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_write_file.php");class Smarty_Adapter implements Yaf_View_Interface{    /**     * Smarty object     * @var Smarty     */    public $_smarty;     /**     * Constructor     *     * @param string $tmplPath     * @param array $extraParams     * @return void     */    public function __construct($tmplPath = null, $extraParams = array()) {        $this->_smarty = new Smarty;          if (null !== $tmplPath) {            $this->setScriptPath($tmplPath);        }               foreach ($extraParams as $key => $value) {            $this->_smarty->$key = $value;         }           }     /**     * Return the template engine object     *     * @return Smarty     */    public function getEngine() {        return $this->_smarty;    }     /**     * Set the path to the templates     *     * @param string $path The directory to set as the path.     * @return void     */    public function setScriptPath($path)    {        if (is_readable($path)) {            $this->_smarty->template_dir = $path;            return;         }                throw new Exception('Invalid path provided');    } /**     * Retrieve the current template directory     *     * @return string     */    public function getScriptPath()    {        return $this->_smarty->template_dir;    }    /**     * Alias for setScriptPath     *     * @param string $path     * @param string $prefix Unused     * @return void     */    public function setBasePath($path, $prefix = 'Zend_View')    {        return $this->setScriptPath($path);    }    /**     * Alias for setScriptPath     *     * @param string $path     * @param string $prefix Unused     * @return void     */    public function addBasePath($path, $prefix = 'Zend_View')    {        return $this->setScriptPath($path);    }    /**     * Assign a variable to the template     *     * @param string $key The variable name.     * @param mixed $val The variable value.     * @return void     */    public function __set($key, $val)    {        $this->_smarty->assign($key, $val);    }    /**     * Allows testing with empty() and isset() to work     *     * @param string $key     * @return boolean     */    public function __isset($key)    {        return (null !== $this->_smarty->get_template_vars($key));    }    /**     * Allows unset() on object properties to work     *     * @param string $key     * @return void     */    public function __unset($key)    {        $this->_smarty->clear_assign($key);    }    /**     * Assign variables to the template     *     * Allows 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, $value = null) {        if (is_array($spec)) {            $this->_smarty->assign($spec);            return;        }        $this->_smarty->assign($spec, $value);    }    /**     * 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() {        $this->_smarty->clear_all_assign();    }    /**     * Processes a template and returns the output.     *     * @param string $name The template to process.     * @return string The output.     */    public function render($name, $value = NULL) {        return $this->_smarty->fetch($name);    }    public function display($name, $value = NULL) {        echo $this->_smarty->fetch($name);    }}

3.4,smarty配置文件。

        再来看看我们的conf/application.ini文件

[common]application.directory = APP_PATH "/application"application.dispatcher.catchException = TRUEapplication.view.ext="tpl"[smarty : common] ;configures for smartysmarty.left_delimiter   = "{#"  smarty.right_delimiter  = "#}"  smarty.template_dir     = APP_PATH "/application/views/"smarty.compile_dir      = '/data1/www/cache/' smarty.cache_dir        = '/data1/www/cache/' [product : smarty] 

3.5,验证

新建一个controller,添加方法:

public function twoAction() {        $this->getView()->assign('content', 'hello World');    }

新建一个模板two.tpl
