Yii 设置简写或者全局函数

新建一个文件 globals.php  在里面可以加入自己想添加的函数

 然后在index.php 引用它

require('path/to/globals.php');

/**
 * This is the shortcut to DIRECTORY_SEPARATOR
 */
defined('DS') or define('DS',DIRECTORY_SEPARATOR);
 
/**
 * 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 CHtml::link()
 */
function l($text, $url = '#', $htmlOptions = array()) 
{
    return CHtml::link($text, $url, $htmlOptions);
}
 
/**
 * This is the shortcut to Yii::t() with default category = 'stay'
 */
function t($message, $category = 'stay', $params = array(), $source = null, $language = null) 
{
    return Yii::t($category, $message, $params, $source, $language);
}
 
/**
 * 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 bu($url=null) 
{
    static $baseUrl;
    if ($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];
}
