PHP实现支持GET,POST,Multipart/form-data的HTTP请求类 - 摘要: 本文讲的是PHP实现支持GET,POST,Multipart/form-data的HTTP请求类,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 /** HttpReque

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:

demo示例程序如下:
<?php require('HttpRequest.class.php');  $config = array(       'ip' => 'demo.fdipzone.com', // 如空则用host代替       'host' => 'demo.fdipzone.com',       'port' => 80,       'errno' => '',       'errstr' => '',       'timeout' => 30,       'url' => '/getapi.php',       //'url' => '/postapi.php',       //'url' => '/multipart.php' );  $formdata = array(   'name' => 'fdipzone',   'gender' => 'man' );  $filedata = array(   array(     'name' => 'photo',     'filename' => 'photo.jpg',     'path' => 'photo.jpg'   ) );  $obj = new HttpRequest(); $obj->setConfig($config); $obj->setFormData($formdata); $obj->setFileData($filedata); $result = $obj->send('get'); //$result = $obj->send('post'); //$result = $obj->send('multipart');  echo '<pre>'; print_r($result); echo '</pre>';  ?>
