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>
希望本文所述对大家php程序设计有所帮助。
