这篇文章主要介绍了PHP封装CURL扩展类,实例分析了基于curl发送post、get请求及操作cookie等相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了PHP封装CURL扩展类。分享给大家供大家参考。具体如下:
- <?php

- /**
- * @编码规范
- * @class 类名首字母大写,类名为多个单词, 每个大字首字母大写 eg: class Curl , class CurlPage
- * @variable 变量名小写, 变量名为多个单词, 每个单词小写,使用下划线_分割 eg: $curl_result
- * @function 函数名与类名规则相同 eg: function SendRequest
- * @params 函数形参规则与变量名相同
- * @class-variable 成员变量,以下划线结尾,多个单词使用下划线分隔. eg: private $host_name_
