本文实例讲述了两个PHP curl封装类的用法实例，这两个函数可以让我们非常的方便的使用PHP curl相关函数。分享给大家供大家参考。具体如下：
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)
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:
"http://www.xx.com/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：
代码如下:
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')));
}
}

//是否显示头部信息

用法
GET用法：
代码如下:
get('//www.jb51.cc/');
POST用法：
代码如下:
get('//www.jb51.cc/','p=1&time=0′);
