这里不讲yii的特性，主要说一说使用yii时对curl的再次封装。

先看看yii的配置文件，在main.php中将curl配置为Components。

       'components' => array(
       
         // Curl库  调用：Yii::app()->curl
         'curl' => array(
            'class' => 'ext.curl.Curl',
            'options' => array(
                CURLOPT_HTTPHEADER => array('Expect:'),
                CURLOPT_HEADER => '',
            ),
        ),

<?php
