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

<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

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 ( $file ) === false) {
   exit( __file__.' '.__line__."<br/>view file {$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"，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

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

<html>
<head>
<title>a smarty adapter example</title>
</head>
<body>
{#$content#}
</body>
</html>
