本篇文章是对PHP中的CURL用法进行了详细的分析介绍，需要的朋友参考下

如下所示：

复制代码 代码如下:

header('Context-Type:text/html;charset:gb2312;');
$urls = array(
'http://www.baidu.com/',
'http://www.pconline.com.cn/',
'http://www.163.com/'
);
$options = array(
CURLOPT_RETURNTRANSFER=>1,
CURLOPT_FOLLOWLOCATION=>1,
CURLOPT_HEADER => false,
CURLOPT_HTTPHEADER => array(
'Accept'=>' text/html, application/xhtml+xml,',
'Accept-Encoding'=>' gzip, deflate',
'Accept-Language'=>' zh-CN',
'Connection'=>' Keep-Alive',
'User-Agent'=>' Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)',
),
);
function curlMultiRequest($urls,$options=array()){
$ch = array();
$results = array();
$mh = curl_multi_init();
foreach($urls as $key=>$val){
$ch[$key] = curl_init();
if($options){
curl_setopt_array($ch[$key],$options);
}
curl_setopt($ch[$key],CURLOPT_URL,$val);
curl_multi_add_handle($mh,$ch[$key]);
}

$running = null;
do{
curl_multi_exec($mh,$running);
}while($running>0);

foreach($ch as $key=>$val){
//$results[$key] = iconv('gb2312','utf-8',curl_multi_getcontent($val));
$results[$key] = curl_multi_getcontent($val);
curl_multi_remove_handle($mh,$val);
curl_close($val);
}
curl_multi_close($mh);
return $results;
}
$results = curlMultiRequest($urls,$options);
print_r($results);
?>
