How to remove chinese characters in a string

Question

is there any easy way to truncate chinese characters i found that regexp but it doesn't work as expected

<?php
$data1='疯狂的管道Test';
$data2='睡眠帮手-背景乐Test';

echo str_replace(preg_replace("/[^\x{4e00}-\x{9fa5}]+/u", '', $data1),'',$data1)
."<br>\n".
str_replace(preg_replace("/[^\x{4e00}-\x{9fa5}]+/u", '', $data2),'',$data2);
exit;

it works for data1 but not data2

Answer 1

You can use a Unicode character property (Han should work for you):

preg_replace("/\p{Han}+/u", '', $data)
