This article mainly introduces PHP to send posts, get requests and operate cookies based on curl. Friends who are interested can refer to it. I hope it will be helpful to everyone.

The details are as follows:

* @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_
