本文實(shí)例講述了yii，CI，yaf框架+smarty模板使用方法。分享給大家供大家參考，具體如下：
最近折騰了框架的性能測(cè)試，其中需要測(cè)試各個(gè)模板跟smarty配合的性能，所以折騰了一桶，現(xiàn)總結(jié)一下。之前已經(jīng)寫過(guò)kohana框架+smarty模板，這里不再重復(fù)了。
一、yii框架+smarty模板
yii是覆蓋了viewRenderer組件。
1.1，下載yii框架并解壓，下載smarty框架并解壓，將smarty/libs文件夾拷到y(tǒng)ii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', // 這里為Smarty支持的屬性 '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(jīng)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 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(yàn)證
新建一個(gè)HelloController.php
<?phpclass HelloController extends Controller { public function actionWorld() { $this->render('world', array('content'=>'hello world')); }} 新建一個(gè)word.html
<body>{#$content#}</body> 二、CI框架+smarty模板
網(wǎng)上很多方法，將smarty作為一個(gè)普通的library，在使用的時(shí)候，controller代碼類似于下面：
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自帶的使用模板的方法
復(fù)制代碼代碼如下:
$this->load->view();
不和諧，而且要一系列的
復(fù)制代碼代碼如下:
$this->smarty->assign();
語(yǔ)句，麻煩不說(shuō)，還破壞了原本CI的簡(jiǎn)潔美，所以果斷唾棄之。
那怎么保持CI加載view時(shí)的簡(jiǎn)潔美呢，答案就是覆蓋Loader類的view()方法。好吧，let's begin。
2.1，條件：
到官網(wǎng)上現(xiàn)在CI框架和smarty模板。
2.2，確保CI已經(jīng)能跑起來(lái)
將CI框架解壓到網(wǎng)站跟目錄下，先寫一個(gè)不帶smarty模板的controller輸出“hello world”。
2.3，引入smarty
將smarty解壓，將libs文件夾考到application/third_paty下面，并將libs重命名smarty，重命名取什么都o(jì)k了，這里就叫smarty吧。
2.4，覆蓋loader類的view()方法
因?yàn)関iew()方法在Loader類里，所以我要覆蓋Loader的view()方法。
先看看$this->load->view()是怎么工作的？CI_Controller類的構(gòu)造函數(shù)里有這么一行
復(fù)制代碼代碼如下:
$this->load =& load_class('Loader', 'core');
load_class函數(shù)會(huì)先在application/core下面找config_item('subclass_prefix').Loader.php文件，找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在配置文件里寫的你要繼承CI核心類的子類的前綴。我使用的是默認(rèn)值'MY_'。找到文件后，require該文件，然后new MY_Loader（如果application/core/MY_Loader.php存在），或者是new Loader，賦值給$this->load。
在application/core下面新建一個(gè)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 ( $file ) === false) { exit( __FILE__.' '.__LINE__."<br/>View file {$file} does not exist, <br/>{$file} => {$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(lái)驗(yàn)證一下吧。
2.5，驗(yàn)證
在controller下面建一個(gè)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', $data); }} 在views下面建一個(gè)index_2.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script src='<!--{$base_url}-->js/jquery.min.js' type='text/javascript' ></script> <link href="<!--{$base_url}-->css/login.css" rel="stylesheet" type="text/css" /> <title>smarty安裝測(cè)試</title></head><body><h1>{#$title#}</h1><p>{#$body#}</p><ul> {#foreach from=$myarray item=v#} <li>{#$v#}</li> {#/foreach#}</ul></body></html> 好了，可以試試你的成果了。
三、yaf框架+smarty模板
yaf是利用引導(dǎo)文件Bootstrap.php來(lái)加載smarty。
3.1，使用Bootstrap
在index.php中用
復(fù)制代碼代碼如下:
$app->bootstrap()->run();
引入Bootstrap.php文件
3.2，在application/Bootstrap.php文件中導(dǎo)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解壓后放到application/library文件夾下，重命名為Smarty。在Smarty下新建Adapter.php，確保Smarty.class.php在Smarty/libs/下。Adapter.php內(nèi)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。
再來(lái)看看我們的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，驗(yàn)證
新建一個(gè)controller，添加方法：
public function twoAction() { $this->getView()->assign('content', 'hello World');} 新建一個(gè)模板two.tpl
<html><head><title>A Smarty Adapter Example</title></head><body>{#$content#}</body></html> 希望本文所述對(duì)大家PHP程序設(shè)計(jì)有所幫助。
