这样的，我希望去除T15:43:28Z这段，规律是T开头,Z结尾.

我机器上只有PHP环境,看得点东PHP，其他的程序完全不懂............

求高手指教。。。。。。。

    用PHP处理小文件可以，文件大了还是用sed比较快
    sed -i "s/T.*Z//g" test.txt

      如果用正则匹配的话，可能注册的用户名中也有TZ字符，所以可以考虑字符串截取 毕竟T17:15:08Z,2016-06-16这一段的长度是固定的

        用正则

        $subject = '6691.club,已经注册,2015-06-17T17:15:08Z,2016-06-16'; $pattern = '/(.*,[\d]{4}-[\d]{2}-[\d]{2})T[\d:]{8}Z(,[\d]{4}-[\d]{2}-[\d]{2}$)/'; preg_match($pattern, $subject, $matches); print_r($matches); /* Array ( [0] => 6691.club,已经注册,2015-06-17T17:15:08Z,2016-06-16 [1] => 6691.club,已经注册,2015-06-17 [2] => ,2016-06-16 ) */

          $result = preg_replace("/T\d{2}:\d{2}:\d{2}Z/", " ", $str); $str 是你的文本

            谢谢各位，通过学习楼上诸位的代码,我自己学习加工了下：
            全段代码如下：

            \n"; echo preg_replace('/\w\d\d\:\d\d\:\d\d\w/',"",$buffer)."
            \n"; } if (! feof ( $handle )) { echo "Error: unexpected fgets() fail\n" ; } fclose ( $handle ); } ?>

            基本上达到我要的目的了，再次感谢楼上各位的帮忙
