yii，CI，yaf架構+smarty模板使用方法_php執行個體

本文執行個體講述了yii，CI，yaf架構+smarty模板使用方法。分享給大家供大家參考，具體如下：

最近折騰了架構的效能測試，其中需要測試各個模板跟smarty配合的效能，所以折騰了一桶，現總結一下。之前已經寫過kohana架構+smarty模板，這裡不再重複了。

一、yii架構+smarty模板

yii是覆蓋了viewRenderer組件。

1.1，下載yii架構並解壓，下載smarty架構並解壓，將smarty/libs檔案夾拷到yii架構application/protected/vendors下面，並重新命名smarty。

1.2，yii設定檔main.php

'components'=>array( 'viewRenderer' => array(  'class'=>'batman.protected.extensions.SmartyViewRender',  // 這裡為Smarty支援的屬性  '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是我已經在index.php定義好的別名。

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

1.3，在protected/extensions/下面建立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 smarty  if (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，驗證

建立一個HelloController.php

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

建立一個word.html

{#$content#}

二、CI架構+smarty模板

網上很多方法，將smarty作為一個普通的library，在使用的時候，controller代碼類似於下面：

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

這種方法跟CI內建的使用模板的方法
複製代碼 代碼如下:$this->load->view();
不和諧，而且要一系列的
複製代碼 代碼如下:$this->smarty->assign();
語句，麻煩不說，還破壞了原本CI的簡潔美，所以果斷唾棄之。

那怎麼保持CI載入view時的簡潔美呢，答案就是覆蓋Loader類的view()方法。好吧，let's begin。

2.1，條件：

到官網上現在CI架構和smarty模板。

2.2，確保CI已經能跑起來

將CI架構解壓到網站跟目錄下，先寫一個不帶smarty模板的controller輸出“hello world”。

2.3，引入smarty

將smarty解壓，將libs檔案夾考到application/third_paty下面，並將libs重新命名smarty，重新命名取什麼都ok了，這裡就叫smarty吧。

2.4，覆蓋loader類的view()方法

因為view()方法在Loader類裡，所以我要覆蓋Loader的view()方法。

先看看$this->load->view()是怎麼工作的？CI_Controller類的建構函式裡有這麼一行
複製代碼 代碼如下:$this->load =& load_class('Loader', 'core');
load_class函數會先在application/core下面找config_item('subclass_prefix').Loader.php檔案，找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在設定檔裡寫的你要繼承CI核心類的子類的首碼。我使用的是預設值'MY_'。找到檔案後，require該檔案，然後new MY_Loader（如果application/core/MY_Loader.php存在），或者是new Loader，賦值給$this->load。

在application/core下面建立一個MY_Loader.php檔案

<?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模板檔案指向ci的views檔案夾  $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 ( $file ) === false) {   exit( __FILE__.' '.__LINE__."
View file {$file} does not exist, 
{$file} => {$view}");  }  // changed by simeng in order to use smarty debug  foreach ( $vars as $key => $value ) {   $this->smarty->assign ( $key, $value );  }  // render or return  if ($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"，這樣就ok了。我們來驗證一下吧。

2.5，驗證

在controller下面建一個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安裝成功！";  $data['body'] = "歡迎使用smarty模板引";  $arr = array(1=>'zhang',2=>'xing',3=>'wang');  $data['myarray'] = $arr;  $this->load->view('index_2', $data); }}

在views下面建一個index_2.html

    smarty安裝測試
{#$title#}
{#$body#}
  {#foreach from=$myarray item=v#}  
{#$v#}
  {#/foreach#}

好了，可以試試你的成果了。

三、yaf架構+smarty模板

yaf是利用引導檔案Bootstrap.php來載入smarty。

3.1，使用Bootstrap

在index.php中用
複製代碼 代碼如下:$app->bootstrap()->run();

引入Bootstrap.php檔案

3.2，在application/Bootstrap.php檔案中匯入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類

將smarty解壓後放到application/library檔案夾下，重新命名為Smarty。在Smarty下建立Adapter.php，確保Smarty.class.php在Smarty/libs/下。Adapter.php內容：

<?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設定檔。

再來看看我們的conf/application.ini檔案

[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，驗證

建立一個controller，添加方法：

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

建立一個模板two.tpl

A Smarty Adapter Example{#$content#}
