一个正则匹配无法匹配中文，怎样加上中文匹配？

Question

$uploadcon="attach.gif[/img] 其他上传附件：金山词霸.torrent";
//preg_match_all("|(?:/upload/)?(\w+\.\w+)|",$uploadcon,$regs);
preg_match_all("/(upload\/)?([a-zA-Z0-9_".chr(0x80)."-".chr(0xff)."]+\.[a-zA-Z0-9]+)/",$uploadcon,$regs);
print_r($regs);中文到底是0x80-0xff还是0xa1-0xff我不清楚.
不过应该对你的程序不打紧吧。

Answer 1

asc码0x80以下都是单字节字符.

Answer 2

$uploadcon="attach.gif[/img] 其他上传附件：金山词霸.torrent";
//preg_match_all("|(?:/upload/)?(\w+\.\w+)|",$uploadcon,$regs);
//preg_match_all("/(upload\/)?([a-zA-Z0-9_".chr(0x80)."-".chr(0xff)."]+\.[a-zA-Z0-9]+)/",$uploadcon,$regs);
preg_match_all("/(upload\/)?([a-zA-Z0-9_\x80-\xff]+\.[a-zA-Z0-9]+)/",$uploadcon,$regs);
print_r($regs);
简化版.
