对完成某个任务进行计时可使用progress_timer类，这个类对象在退出作用范围后，会输出对象创建后过去的时间，可申请多个类对象，这样可对多个任务进行统计。#inc

Yaf 结合用户自定义的视图(模板)引擎Smarty(Yaf + Smarty)

分类：

php开发

yafsmarty

(1)入口文件：/public/index.php:

define("DS", '/');

define('APPLICATION_PATH', dirname(__FILE__).DS.'..'.DS);//指向public上一级的目录 ../

$application = new Yaf_Application( APPLICATION_PATH . "/conf/application.ini");

$application->bootstrap()->run();

?>

(2)在引导程序

class Bootstrap extends Yaf_Bootstrap_Abstract{

public function _initConfig() {

//把配置保存起来

$arrConfig = Yaf_Application::app()->getConfig();

Yaf_Registry::set('config', $arrConfig);

}

//其他定义忽略......

public function _initSmarty(Yaf_Dispatcher $dispatcher) {

//init smarty view engine

$smarty = new Smarty_Adapter(null, Yaf_Registry::get("config")->get("smarty"));

$dispatcher->setView($smarty);

}

}

(3)添加类，使Smarty_Adapter

首先下载

vim Adapter.php

/*确保Smarty.class.php在Smarty/libs/下*/

Yaf_Loader::import( "Smarty/libs/Smarty.class.php"); /*基类目录为library*/

class Smarty_Adapter implements Yaf_View_Interface /*Smarty_Adapter类为yaf与smarty之间的适配器*/

{

/**

* 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);

}

}

?>

(4)修改

vim application.ini

[common]

application.directory = APPLICATION_PATH "/application"

application.dispatcher.catchException = TRUE

application.bootstrap = APPLICATION_PATH "/application/Bootstrap.php"

application.library = APPLICATION_PATH "/application/library"

application.baseUri = ''

;application.dispatcher.defaultModule = index

application.dispatcher.defaultController = index

application.dispatcher.defaultAction = index

;errors (see Bootstrap::initErrors)

application.showErrors=0

[smarty : common]

application.view.ext="tpl" ;;设置视图文件的后缀为 tpl

;smarty.left_delimiter = "{{" ;设置模板提取值时候的"{"情况

;smarty.right_delimiter = "}}" ;

smarty.template_dir

= APPLICATION_PATH "/application/views/"

smarty.compile_dir

= APPLICATION_PATH "/application/views/templates_c/"

smarty.cache_dir

= APPLICATION_PATH "/application/views/templates_d/"

;smarty.caching = 0;

;smarty.cache_lifetime = 600;
