我想从字符串里抓出房间号，具体格式为以#开始，逗号或者空格结束

但是PHP的preg_match给出的结果比perl的多了一个逗号，请问为什么以及怎么解决
，谢谢

php:
    preg_match('/(#.*?)[ ,]/','112 east coast road #b1-15, 112 katong, singapore 428802', $match);
    if($match) {
    echo "match=".$match[0];
    }
    else {
      echo 'not match';
    }
output: match=#b1-15,

perl:
    use strict;
    
    my $str = "112 east coast road #b1-15, 112 katong, singapore 428802";
    
    if($str =~ /(#.*?)[ ,]/) {
        print "match = $1";
    }
    else {
        print "not match";
    }
output: match=#b1-15
