PHP實現支援GET,POST,Multipart/form-data的HTTP請求類_php技巧

本文執行個體講述了PHP實現支援GET,POST,Multipart/form-data的HTTP請求類及其應用，分享給大家供大家參考。具體如下：

HttpRequest.class.php類檔案如下：

<?php /** HttpRequest class, HTTP請求類，支援GET,POST,Multipart/form-data *  Date:  2013-09-25 *  Author: fdipzone *  Ver:  1.0 * *  Func: *  public setConfig   設定串連參數 *  public setFormdata  設定表單資料 *  public setFiledata  設定檔案資料 *  public send     發送資料 *  private connect    建立串連 *  private disconnect  中斷連線 *  private sendGet    get 方式,處理髮送的資料,不會處理檔案資料 *  private sendPost   post 方式,處理髮送的資料 *  private sendMultipart multipart 方式,處理髮送的資料,傳送檔案推薦使用此方式 */  class HttpRequest{ // class start    private $_ip = '';   private $_host = '';   private $_url = '';   private $_port = '';   private $_errno = '';   private $_errstr = '';   private $_timeout = 15;   private $_fp = null;      private $_formdata = array();   private $_filedata = array();     // 設定串連參數   public function setConfig($config){     $this->_ip = isset($config['ip'])?

demo樣本程式如下：

<?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>';  ?>
