php curl封裝類使用例子

編輯:關於PHP編程

       使用函數之前我們要需要把php curl模塊打開(libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

      開啟php curl函數庫的步驟

      1).去掉windows/php.ini 文件裡;extension=php_curl.dll前面的; /*用 echo phpinfo();查看php.ini的路徑*/

      2).把php5/libeay32.dll,ssleay32.dll復制到系統目錄windows/下

      3).重啟apache

      php curl

     代碼如下  

    <?php

    include_once('curl.class.php');
    $aa =new Curl('');
     $curlOptions = array(
     CURLOPT_URL => "http://ww.ww.ww/addTicket.jsp", //訪問URL
     CURLOPT_RETURNTRANSFER => true, //獲取結果作為字符串返回
     CURLOPT_REFERER => "ww.ww.ww/zw2",
     CURLOPT_HTTPHEADER => array('X-FORWARDED-FOR:139.197.14.19', 'CLIENT-IP:127.0.0.1','Proxy-Client-IP:139.197.14.19','WL-Proxy-Client-IP:139.197.14.19' ),
     CURLOPT_HEADER => 1, //獲取返回頭信息

     //CURLOPT_SSL_VERIFYPEER => false, //支持SSL加密
     CURLOPT_POST => true, //發送時帶有POST參數
     CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //請求的POST參數字符串
     CURLOPT_TIMEOUT => $aa->timeout //等待響應的時間
     );
     echo $aa->getResponseText($curlOptions);

    <?php
    class Curl
    {
    public $cookieFile;
    public $timeout = 160;

    Public function __construct($dir){

    }

    /**

    用法

    GET用法:

    $curl = new Curl();
    $curl->get(‘http://www.111cn.net/’);

    POST用法

    $curl = new Curl();
    $curl->get(‘http://www.111cn.net/’, ‘p=1&time=0′);
