这篇文章主要介绍了PHP实现支持GET,POST,Multipart/form-data的HTTP请求类,包括了连接与处理方式及相关的技巧,需要的朋友可以参考下

本文实例讲述了PHP实现支持GET,POST,Multipart/form-data的HTTP请求类及其应用，分享给大家供大家参考。具体如下：

HttpRequest.class.php类文件如下：

<?php

/** HttpRequest class, HTTP请求类，支持GET,POST,Multipart/form-data

*  Date:  2013-09-25

*  Author: fdipzone

*  Ver:  1.0

*

*  Func:

*  public setConfig   设置连接参数

*  public setFormdata  设置表单数据

*  public setFiledata  设置文件数据

*  public send     发送数据

*  private connect    创建连接

*  private disconnect  断开连接

*  private sendGet    get 方式,处理发送的数据,不会处理文件数据

*  private sendPost   post 方式,处理发送的数据

*  private sendMultipart multipart 方式,处理发送的数据,发送文件推荐使用此方式

);



$filedata = array(

  array(

    'path' => 'photo.jpg'

  )

);

//www.phpfensi.com
