采集网站正则表达式和结果输出问题

采集到输出错误，看看是正则语句问题吗

 function request_by_curl($remote_server, $post_string){    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $remote_server);    curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    curl_setopt($ch, CURLOPT_USERAGENT, "Jimmy's CURL Example beta");    $data = curl_exec($ch);    curl_close($ch);    return $data;}$string = request_by_curl("http://www.bwlc.net/bulletin/keno.html",80);  $pat = '/\[\s\S]*?\(.*?)\<\/td\>[\s\S]*?\(.*?)\<\/td\>[\s\S]*?\(.*?)\<\/td\>[\s\S]*?\(.*?)\<\/td\>[\s\S]*?\<\/tr\>/i';preg_match_all($pat,$string,$outstr);foreach($outstr as $key => $value){ 	echo "第".$outstr[$key][1]."期,开奖

结果为：".$outstr[$key][2]."飞盘：".$outstr[$key][3]."时间：".$outstr[$key][4]."\n";}

回复讨论(解决方案)

你把匹配结果数组的格式理解错了

foreach($outstr[0] as $key => $value){     echo "第".$outstr[1][$key]."期,开奖

结果为：".$outstr[2][$key]."飞盘：".$outstr[3][$key]."时间：".$outstr[4][$key]."\n";}
