      <?php function Curl_http($array,$timeout){
    $res = array();
    $mh = curl_multi_init();//创建多个curl语柄
    $startime = getmicrotime();
    foreach($array as $k=>$url){
        $conn[$k]=curl_init($url);
        curl_setopt($conn[$k], CURLOPT_TIMEOUT, $timeout);//设置超时时间
        curl_setopt($conn[$k], CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');

        curl_setopt($conn[$k], CURLOPT_HEADER, 0);//这里不要header,加块效率

        curl_multi_close($mh);
        $endtime = getmicrotime();
        $diff_time = $endtime - $startime;

        return array('diff_time'=>$diff_time,
               'return'=>$res,
                'header'=>$header

}
 //计算当前时间
 function getmicrotime() {
list($usec, $sec) = explode(" ",microtime());
        return ((float)$usec + (float)$sec);
}

    //测试一下,curl 1个网址
$array = array(
"http://www.120ask.com/keshi.asp?c=69&a=&l=0&p=1",
);
 $data = Curl_http($array,'1');//调用
 var_dump($data);//输出

?>
  


libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll都拷贝到system32目录下,重启apache

PHP.ini 开启了 CURL

但是还是不行 错误提示我

Fatal error: Call to undefined function curl_multi_init() in D:\wamp\www\caiji\caiji.php on line 4

------解决方案--------------------
phpinfo();看看有没有curl,如果没有说明你根本没有开启成功(extension=php_curl.dll)
------解决方案--------------------
那你路劲没设置对,在试试~~
------解决方案--------------------
你看看你phpinfo()里面的php配置文件是你修改的那个吗?例如你把mysql模块关闭了在打开phpinfo()看看mysql模块是否开启,如果依然开启,那么说明你所用的php配置文件并不是你所修改的那个
------解决方案--------------------
标题党.
------解决方案--------------------
php CURL 采集问题---请指教
你应该问:
curl安装不成功---请指教



重启过apache吗,杀死过php-cgi吗。
------解决方案--------------------
这个可以用。
