在网站项目中，没必要把公用的函数写成一个工具类，有时候面向过程其实更方便。
在入口文件index.php里添加
require_once('protected/function.php');
即可对其引用，成为公用的函数集合。
function.php如下：
<? php
/**
* This is the shortcut to DIRECTORY_SEPARATOR
*/
defined ( 'DS' ) or define ( 'DS' , DIRECTORY_SEPARATOR );
defined ( 'TIME' ) or define ( 'TIME' , time ());
defined ( 'MTIME' ) or define ( 'MTIME' , intval ( microtime ( true ))); //返回当前unix时间戳
/**
* This is the shortcut to Yii::app()
*/
function app()
{
return Yii::app();
}
/**
* This is the shortcut to Yii::app()->clientScript
*/
function cs ()
{
// You could also call the client script instance via Yii::app()->clientScript
// But this is faster
return Yii::app()->getClientScript();
}
/**
* This is the shortcut to Yii::app()->user.
*/
function user ()
{
return Yii :: app ()-> getUser ();
}
/**
* This is the shortcut to Yii::app()->createUrl()
*/
function url ( $route , $params = array (), $ampersand = '&' )
{
return Yii :: app ()-> createUrl ( $route , $params , $ampersand );
}
/**
* This is the shortcut to CHtml::encode
*/
/* function h( $text )
{
return htmlspecialchars( $text ,ENT_QUOTES,Yii::app()->charset);
} */
/**
* This is the shortcut to Yii::app()->request->baseUrl
* If the parameter is given, it will be returned and prefixed with the app baseUrl.
*/
function baseDir ( $url = null )
{
//static $baseUrl = null;
//if ( $baseUrl ===null)
$baseUrl =Yii::app()->getRequest()->getBaseUrl();
return $url ===null ? $baseUrl : $baseUrl . '/' .ltrim( $url , '/' );
}
/**
* Returns the named application parameter.
* This is the shortcut to Yii::app()->params[$name].
*/
function param ( $name )
{
return Yii :: app ()-> params [ $name ];
}
/**
* A useful one that I use in development is the following
* which dumps the target with syntax highlighting on by default
*/
function dump ( $target )
{
return CVarDumper :: dump ( $target , 10 , true ) ;
}
function mk_dir ( $dir , $mode = 0777 )
{
if ( is_dir ( $dir ) || @mkdir ( $dir , $mode )) return true ;
if (! mk_dir ( dirname ( $dir ), $mode )) return false ;
return @mkdir ( $dir , $mode );
}
