如何从文本中删除此数字？

нани1,Ñпални1
视频3,教程3,
книги3,ÑÐºÐ°Ñ‡Ð°Ñ 5‚web2.0

above is forieng form of foreign languages which is stored in MySQL. I want to remove numbers from above all lines. say 1 , 3 , 5 etc. and I want to keep web2.0

note:- there are about 300k lines. above is just a sample.

preg_replace('/(\w)\d+$/m', '$1', $tags);

the above one is an option for almost all cases but this fails in above case...

$str = 'нани1,Ñпални1
视频3,教程3,
книги3,ÑÐºÐ°Ñ‡Ð°Ñ 5‚
';

$str = preg_replace('/\d+/', '', $str);

var_dump($str);

Output

string(122) "нани,Ñпални
视频,教程,
книги,ÑÐºÐ°Ñ‡Ð°Ñ ‚
"

CodePad.

Update

<?php

$str = 'нани1,Ñпални1
视频3,教程3,
книги3,ÑÐºÐ°Ñ‡Ð°Ñ 5‚web2.0

';

$str = preg_replace('/(?<!\w|\.)\d+/', '', $str);

var_dump($str);

Output

string(130) "нани,Ñпални
视频,教程,
книги,ÑÐºÐ°Ñ‡Ð°Ñ ‚web2.0

"

I am not sure exactly your exclusions, but this won't match any number proceeded by a word character (\w) or by a period (\.).

Since you tagged this question with php I assume you mean something like this:

<?php
    $string = preg_replace ('/[0-9]+/', '', $string);
?>
