本文實例講述了php實現(xiàn)支持GET,POST,Multipart/form-data的HTTP請求類及其應(yīng)用，分享給大家供大家參考。具體如下：

HttpRequest.class.php類文件如下：

demo示例程序如下：

<?php require('HttpRequest.class.php');  $config = array(       'ip' => 'demo.fdipzone.com', // 如空則用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>';  ?>
