Re-encapsulation of CURL in yii11

The flexible expansion of the Yii framework is favored by the company, so Yii is used in the project. In order to be compatible with the original system, the Yii1.1 version is still chosen.

                                                                                                                                                We not talking about the characteristics of yii here, mainly talking about the re-encapsulation of curl when using yii.

                                                                                                                                                                                                            First take a look at the yii configuration file and configure curl as Components in main.php.

    

       'components' => array(
       
         // Curl库  调用：Yii::app()->curl

The above introduces the re-encapsulation of CURL in yii11, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
