phpyafsmarty,yii，CI，yaf框架+smarty模板使用方法

本文实例讲述了yii&＃xff0c;CI&＃xff0c;yaf框架&＃43;smarty模板使用方法。分享给大家供大家参考&＃xff0c;具体如下&＃xff1a;

最近折腾了框架的性能测试&＃xff0c;其中需要测试各个模板跟smarty配合的性能&＃xff0c;所以折腾了一桶&＃xff0c;现总结一下。之前已经写过kohana框架&＃43;smarty模板&＃xff0c;这里不再重复了。

一、yii框架&＃43;smarty模板

yii是覆盖了viewRenderer组件。

1.1&＃xff0c;下载yii框架并解压&＃xff0c;下载smarty框架并解压&＃xff0c;将smarty/libs文件夹拷到yii框架application/protected/vendors下面&＃xff0c;并重命名smarty。

1.2&＃xff0c;yii配置文件main.php

&＃39;components&＃39;&＃61;>array(

&＃39;viewRenderer&＃39; &＃61;> array(

&＃39;class&＃39;&＃61;>&＃39;batman.protected.extensions.SmartyViewRender&＃39;,

// 这里为Smarty支持的属性

&＃39;config&＃39; &＃61;> array (

&＃39;left_delimiter&＃39; &＃61;> "{#",

&＃39;right_delimiter&＃39; &＃61;> "#}",

&＃39;template_dir&＃39; &＃61;> APP_DIR . "/views/",

&＃39;config_dir&＃39; &＃61;> APP_DIR . "/views/conf/",

&＃39;debugging&＃39; &＃61;> false,

&＃39;compile_dir&＃39; &＃61;> &＃39;D:/temp/runtime&＃39;,

)

)

其中batman是我已经在index.php定义好的别名。

Yii::setPathOfAlias(&＃39;batman&＃39;, dirname(__FILE__));

Yii::import("batman.protected.vendors.*");

define(&＃39;APP_DIR&＃39;, dirname(__FILE__).&＃39;/protected/&＃39;);

1.3&＃xff0c;在protected/extensions/下面新建SmartyViewRender.php

class SmartyViewRender extends CApplicationComponent implements IViewRenderer {

public $fileExtension &＃61; &＃39;.html&＃39;;

private $_smarty &＃61; null;

public $config &＃61; array();

public function init() {

$smartyPath &＃61; Yii::getPathOfAlias(&＃39;batman.protected.vendors.smarty&＃39;);

Yii::$classMap[&＃39;Smarty&＃39;] &＃61; $smartyPath . &＃39;/Smarty.class.php&＃39;;

Yii::$classMap[&＃39;Smarty_Internal_Data&＃39;] &＃61; $smartyPath . &＃39;/sysplugins/smarty_internal_data.php&＃39;;

$this->_smarty &＃61; new Smarty();

// configure smarty

if (is_array ( $this->config )) {

foreach ( $this->config as $key &＃61;> $value ) {

if ($key {0} !&＃61; &＃39;_&＃39;) { // not setting semi-private properties

$this->_smarty->$key &＃61; $value;

}

}

}

Yii::registerAutoloader(&＃39;smartyAutoload&＃39;);

}

public function renderFile($context, $file, $data, $return) {

foreach ($data as $key &＃61;> $value)

$this->_smarty->assign($key, $value);

$return &＃61; $this->_smarty->fetch($file);

if ($return)

return $return;

else

echo $return;

}

}

1.4&＃xff0c;验证

新建一个HelloController.php

class HelloController extends Controller {

public function actionWorld() {

$this->render(&＃39;world&＃39;, array(&＃39;content&＃39;&＃61;>&＃39;hello world&＃39;));

}

}

新建一个word.html

{#$content#}

二、CI框架&＃43;smarty模板

网上很多方法&＃xff0c;将smarty作为一个普通的library&＃xff0c;在使用的时候&＃xff0c;controller代码类似于下面&＃xff1a;

public function index()

{

$this->load->library(&＃39;smarty/Ci_smarty&＃39;, &＃39;&＃39;, &＃39;smarty&＃39;);

$this->smarty->assign("title","恭喜你smarty安装成功&＃xff01;");

$this->smarty->assign("body","欢迎使用smarty模板引擎");

$arr &＃61; array(1&＃61;>&＃39;zhang&＃39;,2&＃61;>&＃39;xing&＃39;,3&＃61;>&＃39;wang&＃39;);

$this->smarty->assign("myarray",$arr);

$this->smarty->display(&＃39;index_2.html&＃39;);

}

这种方法跟CI自带的使用模板的方法

$this->load->view();

不和谐&＃xff0c;而且要一系列的

$this->smarty->assign();

语句&＃xff0c;麻烦不说&＃xff0c;还破坏了原本CI的简洁美&＃xff0c;所以果断唾弃之。

那怎么保持CI加载view时的简洁美呢&＃xff0c;答案就是覆盖Loader类的view()方法。好吧&＃xff0c;let&＃39;s begin。

2.1&＃xff0c;条件&＃xff1a;

到官网上现在CI框架和smarty模板。

2.2&＃xff0c;确保CI已经能跑起来

将CI框架解压到网站跟目录下&＃xff0c;先写一个不带smarty模板的controller输出“hello world”。

2.3&＃xff0c;引入smarty

将smarty解压&＃xff0c;将libs文件夹考到application/third_paty下面&＃xff0c;并将libs重命名smarty&＃xff0c;重命名取什么都ok了&＃xff0c;这里就叫smarty吧。

2.4&＃xff0c;覆盖loader类的view()方法

因为view()方法在Loader类里&＃xff0c;所以我要覆盖Loader的view()方法。

先看看$this->load->view()是怎么工作的&＃xff1f;CI_Controller类的构造函数里有这么一行

$this->load &＃61;& load_class(&＃39;Loader&＃39;, &＃39;core&＃39;);

load_class函数会先在application/core下面找config_item(&＃39;subclass_prefix&＃39;).Loader.php文件&＃xff0c;找不到再到system/core下面找Loader.php。config_item(&＃39;subclass_prefix&＃39;)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&＃39;MY_&＃39;。找到文件后&＃xff0c;require该文件&＃xff0c;然后new MY_Loader(如果application/core/MY_Loader.php存在)&＃xff0c;或者是new Loader&＃xff0c;赋值给$this->load。

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

define(&＃39;DS&＃39;, DIRECTORY_SEPARATOR);

class MY_Loader extends CI_Loader {

public $smarty;

public function __construct() {

parent::__construct();

require APPPATH.&＃39;third_party&＃39;.DS.&＃39;smarty&＃39;.DS.&＃39;smarty.class.php&＃39;;

$this->smarty &＃61; new Smarty ();

// smarty 配置

$this->smarty->template_dir&＃61; APPPATH.&＃39;views&＃39;.DS;//smarty模板文件指向ci的views文件夹

$this->smarty->compile_dir &＃61; &＃39;d:/temp/tpl_c/&＃39;;

$this->smarty->config_dir &＃61; APPPATH.&＃39;libraries/smarty/configs/&＃39;;

$this->smarty->cache_dir &＃61; &＃39;d:/temp/cache&＃39;;

$this->smarty->left_delimiter &＃61; &＃39;{#&＃39;;

$this->smarty->right_delimiter &＃61; &＃39;#}&＃39;;

}

public function view($view, $vars &＃61; array(), $return &＃61; FALSE)

{

// check if view file exists

$view .&＃61; config_item(&＃39;templates_ext&＃39;);

$file &＃61; APPPATH.&＃39;views&＃39;.DS.$view;

if (! file_exists ( $file ) || realpath ( $file ) &＃61;&＃61;&＃61; false) {

exit( __FILE__.&＃39; &＃39;.__LINE__."
View file {$file} does not exist,
{$file} &＃61;> {$view}");

}

// changed by simeng in order to use smarty debug

foreach ( $vars as $key &＃61;> $value ) {

$this->smarty->assign ( $key, $value );

}

// render or return

if ($return) {

ob_start ();

}

$this->smarty->display ( $view );

if ($return) {

$res &＃61; ob_get_contents ();

ob_end_clean ();

return $res;

}

}

}

我把template_ext配置成了".html"&＃xff0c;这样就ok了。我们来验证一下吧。

2.5&＃xff0c;验证

在controller下面建一个home.php

class Home extends CI_Controller {

public function index() {

$data[&＃39;todo_list&＃39;] &＃61; array(&＃39;Clean House&＃39;, &＃39;Call Mom&＃39;, &＃39;Run Errands&＃39;);

$data[&＃39;title&＃39;] &＃61; "恭喜你smarty安装成功&＃xff01;";

$data[&＃39;body&＃39;] &＃61; "欢迎使用smarty模板引";

$arr &＃61; array(1&＃61;>&＃39;zhang&＃39;,2&＃61;>&＃39;xing&＃39;,3&＃61;>&＃39;wang&＃39;);

$data[&＃39;myarray&＃39;] &＃61; $arr;

$this->load->view(&＃39;index_2&＃39;, $data);

}

}

在views下面建一个index_2.html

{#$body#}

{#foreach from&＃61;$myarray item&＃61;v#}

{#/foreach#}

好了&＃xff0c;可以试试你的成果了。

三、yaf框架&＃43;smarty模板

yaf是利用引导文件Bootstrap.php来加载smarty。

3.1&＃xff0c;使用Bootstrap

在index.php中用

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

引入Bootstrap.php文件

3.2&＃xff0c;在application/Bootstrap.php文件中导入smarty。

class Bootstrap extends Yaf_Bootstrap_Abstract {

public function _initSmarty(Yaf_Dispatcher $dispatcher) {

$smarty &＃61; 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&＃xff0c;重命名为Smarty。在Smarty下新建Adapter.php&＃xff0c;确保Smarty.class.php在Smarty/libs/下。Adapter.php内容&＃xff1a;

Yaf_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

{

/**

public function __construct($tmplPath &＃61; null, $extraParams &＃61; array()) {

$this->_smarty &＃61; new Smarty;

if (null !&＃61;&＃61; $tmplPath) {

foreach ($extraParams as $key &＃61;> $value) {

$this->_smarty->$key &＃61; $value;

{

if (is_readable($path)) {

$this->_smarty->template_dir &＃61; $path;

return;

}

throw new Exception(&＃39;Invalid path provided&＃39;);

}

/**

* Retrieve the current template directory

*

* &＃64;return string

*/

public function getScriptPath()

{

return $this->_smarty->template_dir;

}

/**

*

public function setBasePath($path, $prefix &＃61; &＃39;Zend_View&＃39;)

{

return $this->setScriptPath($path);

}

/**

* &＃64;return void

*/

public function addBasePath($path, $prefix &＃61; &＃39;Zend_View&＃39;)

{

return $this->setScriptPath($path);

}

/**

*/

public function __set($key, $val)

{

$this->_smarty->assign($key, $val);

}

/**

*/

public function __isset($key)

{

public function assign($spec, $value &＃61; null) {

return;

}

$this->_smarty->assign($spec, $value);

}

return $this->_smarty->fetch($name);

}

public function display($name, $value &＃61; NULL) {

echo $this->_smarty->fetch($name);

}

}

3.4&＃xff0c;smarty配置文件。

再来看看我们的conf/application.ini文件

[common]

application.directory &＃61; APP_PATH "/application"

application.dispatcher.catchException &＃61; TRUE

application.view.ext&＃61;"tpl"

[smarty : common]

;configures for smarty

smarty.left_delimiter &＃61; "{#"

smarty.right_delimiter &＃61; "#}"

smarty.template_dir &＃61; APP_PATH "/application/views/"

smarty.compile_dir &＃61; &＃39;/data1/www/cache/&＃39;

smarty.cache_dir &＃61; &＃39;/data1/www/cache/&＃39;

[product : smarty]

3.5&＃xff0c;验证

新建一个controller&＃xff0c;添加方法&＃xff1a;

public function twoAction() {

$this->getView()->assign(&＃39;content&＃39;, &＃39;hello World&＃39;);

}

新建一个模板two.tpl
