這樣的，我希望去除T15:43:28Z這段，規律是T開頭,Z結尾.

我機器上只有PHP環境,看得點東PHP，其他的程式完全不懂............

求高手指教。。。。。。。

用PHP處理小檔案可以，檔案大了還是用sed比較快
sed -i "s/T.*Z//g" test.txt

如果用正則匹配的話，可能註冊的使用者名稱中也有TZ字元，所以可以考慮字串截取 畢竟T17:15:08Z,2016-06-16這一段的長度是固定的

用正則

$subject = '6691.club,已經註冊,2015-06-17T17:15:08Z,2016-06-16';$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,已經註冊,2015-06-17T17:15:08Z,2016-06-16[1] => 6691.club,已經註冊,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

謝謝各位，通過學習樓上諸位的代碼,我自己學習加工了下：
全段代碼如下：

\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 );} ?> 

基本上達到我要的目的了，再次感謝樓上各位的幫忙
