求一正则

[littlebirds]

preg_match_all('/([\w.]+)-\d{3}\w\d/',$types,$new_type);
print_r($new_type);

得到的结果中含有TSXXX-XXXXX的结果，如果 - 前段不含TS字段，怎么求？

感觉我这个匹配有点问题，但匹配到的数据是对的.....

preg_match_all('/(?!TS|yoh)(.+-\w{5})\s/',$str,$m);
Array
(
    [0] => MEC752-010B1
    [1] => MEC752-020B1
    [2] => MEC753-010C1
    [3] => MEC91-100E1
    [4] => MEC91-100F1
    [5] => MEC91-100H2
    [6] => FI03-002A1
    [7] => FI03-022A1
)

引用 2 楼 xuzuning 的回复:

请问这样的形式怎么抓？ ./dat/TS404/BEM212-500A1/4403 preg_match_all('/d\w\d+/',$s,$m);取不到4403这个值。
