6682.club,已经注册,2015-06-17T15:43:28Z,2016-06-16

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
