求助正责表达式
我要得到分集连接，
但是结果是 连接多了点，要去掉。主要是匹配范围的时候多了点内容，不知道怎么样去掉。还请知点一下。、
我要得到的效果是：
- CSS code
([\s\S]*?)/isU' ,$str , $match);
preg_match_all('/href="([\s\S]*?)"/' , $match[1][0], $href );
print_r($href);exit();
function getHtml($url){
if(function_exists('file_get_contents')){
$file_contents = file_get_contents($url);
}
else{
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
}
return $file_contents;
}
