标题 php的curl封装类用法实例
内容
    使用函数之前我们要需要把php curl模块打开(libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)
    开启php curl函数库的步骤
    1).去掉windows/php.ini 文件里;extension=php_curl.dll前面的; /*用 echo phpinfo();查看php.ini的路径*/
    2).把php5/libeay32.dll，ssleay32.dll复制到系统目录windows/下
    3).重启apache
    代码如下：
    代码如下:
    <?php
    include_once('curl.class.php');
    $aa =new Curl('');
    $curlOptions = array(
    CURLOPT_URL => "", //访问URL
    CURLOPT_RETURNTRANSFER => true, //获取结果作为字符串返回
    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, //获取返回头信息
    //CURLOPT_SSL_VERIFYPEER => false, //支持SSL加密
    CURLOPT_POST => true, //发送时带有POST参数
    CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //请求的POST参数字符串
    CURLOPT_TIMEOUT => $aa->timeout //等待响应的时间
    );
    echo $aa->getResponseText($curlOptions);
    cul处理类：
    代码如下:
    <?php
    class Curl
    {
    public $cookieFile;
    public $timeout = 160;
    Public function __construct($dir){
    $this->cookieFile = $this->getTemporaryCookieFileName($dir);
    }
    /**
    * 设置CURL参数并发送请求，获取响应内容
    * @access private
    * @param $curlOptions array curl设置参数数组
    * @return string|false 访问成功，按字符串形式返回获取的信息；否则返回false
    */
    public function getResponseText($curlOptions) {
    /* 设置CURLOPT_RETURNTRANSFER为true */
    if(!isset($curlOptions[CURLOPT_RETURNTRANSFER]) || $curlOptions[CURLOPT_RETURNTRANSFER] == false) {
    $curlOptions[CURLOPT_RETURNTRANSFER] = true;
    }
    /* 初始化curl模块 */
    $curl = curl_init();
    /* 设置curl选项 */
    curl_setopt_array($curl, $curlOptions);
    /* 发送请求并获取响应信息 */
    $responseText = '';
    try {
    $responseText = curl_exec($curl);
    if(($errno = curl_errno($curl)) != CURLM_OK) {
    $errmsg = curl_error($curl);
    throw new Exception($errmsg, $errno);
    }
    } catch (Exception $e) {
    //exceptionDisposeFunction($e);
    //print_r($e);
    $responseText = false;
    }
    /* 关闭curl模块 */
    curl_close($curl);
    /* 返回结果 */
    return $responseText;
    }
    /**
    * 将Unicode字符串(u0000)转化为utf-8字符串，工具函数
    * @access private
    * @static
    * @param $string string Unicode字符串
    * @return string utf-8字符串
    */
    public function unicodeToUtf8($string) {
    $string = str_replace('u', '', strtolower($string));
    $length = strlen($string) / 4;
    $stringResult = '';
    for($i = 0; $i < $length; $i++) {
    $charUnicodeHex = substr($string, $i * 4, 4);
    $unicodeCode = hexdec($charUnicodeHex);
    $utf8Code = '';
    if($unicodeCode < 128) {
    $utf8Code = chr($unicodeCode);
    } else if($unicodeCode < 2048) {
    $utf8Code .= chr(192 + (($unicodeCode - ($unicodeCode % 64)) / 64));
    $utf8Code .= chr(128 + ($unicodeCode % 64));
    } else {
    $utf8Code .= chr(224 + (($unicodeCode - ($unicodeCode % 4096)) / 4096));
    $utf8Code .= chr(128 + ((($unicodeCode % 4096) - ($unicodeCode % 64)) / 64));
    $utf8Code .= chr(128 + ($unicodeCode % 64));
    }
    $stringResult .= $utf8Code;
    }
    return $stringResult;
    }
    private function getTemporaryCookieFileName($dir='.') {
    return (str_replace("", '/', tempnam($dir, 'tmp')));
    }
    }
    代码如下:
    例子2
    代码如下:
    <?php
    //curl类
    class Curl
    {
    function Curl(){
    return true;
    }
    function execute($method, $url, $fields='', $userAgent='', $httpHeaders='', $username='', $password=''){

    if(false === $ch){
    return false;
    }
    if(is_string($url) && strlen($url)){

    }else{

    }
    //是否显示头部信息

    }
    $fields = implode('&',$sets);
    }
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    }else if('put' == $method){
    curl_setopt($ch, CURLOPT_PUT, true);
    }
    //curl_setopt($ch, CURLOPT_PROGRESS, true);
    //curl_setopt($ch, CURLOPT_VERBOSE, true);
    //curl_setopt($ch, CURLOPT_MUTE, false);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);//设置curl超时秒数
    if(strlen($userAgent)){
    curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
    }
    if(is_array($httpHeaders)){
    curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);
    }
    $ret = curl_exec($ch);
    if(curl_errno($ch)){
    curl_close($ch);
    return array(curl_error($ch), curl_errno($ch));
    }else{
    curl_close($ch);
    if(!is_string($ret) || !strlen($ret)){
    return false;
    }
    return $ret;
    }
    }
    function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){

    }
    }
    ?>
    用法
    GET用法：
    代码如下:
    $curl = new Curl();
    $curl->get('http://www.jb51.net/');
    POST用法：
    代码如下:
    $curl = new Curl();
    $curl->get('http://www.jb51.net/', 'p=1&time=0′);
