【有缺項的正規表示式-2???】

之前發的例子後來成功解決了
程式碼如下

preg_match_all('/\(([A-Z0-9]+-\d+)\)\)-\d+ L?A?G?\/?(\d+\/\d+\/?\d?|[A-Z]+_\d{2}_\w+|\d+\/\d+\/\d+)-?(?:(vlan\/|qinq\/)(\d+.\d+|\d+))?(\s+|\{.*\}\s+)(\d+\/\d+|lag\/\d+||\d+\/\d+\/\d+)-?(vlan\/|qinq\/)(\d+.\d+|\d+)/i',$f,$matches);
print_r($matches[1]);
echo "<hr>";
print_r($matches[2]);
echo "<hr>";
print_r($matches[4]);
echo "<hr>";
print_r($matches[6]);
echo "<hr>";
print_r($matches[8]);

但後來遇到下面的狀況
我想舉一反三
把後面的
(\d+\/\d+|lag\/\d+||\d+\/\d+\/\d+)-?(vlan\/|qinq\/)(\d+.\d+|\d+)
包成
(?:(\d+\/\d+|lag\/\d+||\d+\/\d+\/\d+)-?(vlan\/|qinq\/)(\d+.\d+|\d+))?
但結果不是我想像的一樣耶
