本文实例讲述了yii，CI，yaf框架+smarty模板使用方法。分享给大家供大家参考，具体如下：
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+smarty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
<?php
class 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，验证
新建一个HelloController.php
<?php
class HelloController extends Controller {
public function actionWorld() {
$this->render('world', array('content'=>'hello world'));
}
}
新建一个word.html
{#$content#}
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);
$this->smarty->display('index_2.html');
}
这种方法跟CI自带的使用模板的方法
复制代码 代码如下:$this->load->view();
不和谐，而且要一系列的
复制代码 代码如下:$this->smarty->assign();
语句，麻烦不说，还破坏了原本CI的简洁美，所以果断唾弃之。
那怎么保持CI加载view时的简洁美呢，答案就是覆盖Loader类的view()方法。好吧，let's begin。
2.1，条件：
到官网上现在CI框架和smarty模板。
2.2，确保CI已经能跑起来
将CI框架解压到网站跟目录下，先写一个不带smarty模板的controller输出“hello world”。
2.3，引入smarty
将smarty解压，将libs文件夹考到application/third_paty下面，并将libs重命名smarty，重命名取什么都ok了，这里就叫smarty吧。
2.4，覆盖loader类的view()方法
因为view()方法在Loader类里，所以我要覆盖Loader的view()方法。
先看看$this->load->view()是怎么工作的？CI_Controller类的构造函数里有这么一行
复制代码 代码如下:$this->load =& load_class('Loader', 'core');
load_class函数会先在application/core下面找config_item('subclass_prefix').Loader.php文件，找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在配置文件里写的你要继承CI核心类的子类的前缀。我使用的是默认值'MY_'。找到文件后，require该文件，然后new MY_Loader（如果application/core/MY_Loader.php存在），或者是new Loader，赋值给$this->load。
在application/core下面新建一个MY_Loader.php文件
<?php
define('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 ( $file ) === false) {
exit( __FILE__.' '.__LINE__."View file {$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"，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', $data);
}
}
在views下面建一个index_2.html
smarty安装测试 {#$title#}
{#$body#}
-
{#foreach from=$myarray item=v#}
- {#$v#} {#/foreach#}
好了，可以试试你的成果了。
三、yaf框架+smarty模板
yaf是利用引导文件Bootstrap.php来加载smarty。
3.1，使用Bootstrap
在index.php中用
复制代码 代码如下:$app->bootstrap()->run();
引入Bootstrap.php文件
3.2，在application/Bootstrap.php文件中导入smarty。
<?php
class 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：
<?php
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
{
/**
* 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 = TRUE
application.view.ext="tpl"
[smarty : common]
;configures for smarty
smarty.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() {
$this->getView()->assign('content', 'hello World');
}
新建一个模板two.tpl
A Smarty Adapter Example {#$content#}
希望本文所述对大家PHP程序设计有所帮助。
