php curl封装类使用例子
下面整理两个php curl封装类使用例子，这两个函数可以让我们非常的方便的使用php curl相关函数，下面我们一起来看看吧。
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
php curl
<?php
include_once ('curl.class.php');
$aa = new Curl('');
$curlOptions = array(
CURLOPT_URL => "http://ww.ww.ww/addTicket.jsp", //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
<?php
class Curl {
public $cookieFile;
public $timeout = 160;
Public function __construct($dir) {
$this->cookieFile = $this->getTemporaryCookieFileName($dir);
}

*/

$curlOptions[CURLOPT_RETURNTRANSFER] = true;
}
/* 初始化curl模块 */
$curl = curl_init();
/* 设置curl选项 */

//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++) {

?>用法
GET用法：
$curl = new Curl();
$curl->get('http://www.phprm.com/');
POST用法
$curl = new Curl();
$curl->get('http://www.phprm.com/', 'p=1&time=0');教程网址:http://www.phprm.com/function/63721.html
