or

(程序不会自动创建数据库，请提前创建一个空数据库或使用已有数据库)

preg_replace("/(?:[(]([\p{Han}]+)[)] )?/ux", '-', $val);

but the result is not obtained, what am I doing wrong?

Answer 1

$str = "emMsg('您的php版本过低，请选用支持PHP5的环境安装english word。');";
$res = preg_replace( "~emMsg\(('*)(.+?)('*)\);~", 'emMsg(\\1-\\3);', $str );
print_r( $res );

IS this what you mean?

$str = "emMsg('您的php版本过低，请选用支持PHP5的环境安装english word。');";
$str = preg_replace( "~\p{Han}+~u", '', $str );
$res = preg_replace( "~emMsg\(('*)(.+?)('*)\);~", 'emMsg(\\1\\2\\3);', $str );
print_r( $res );

I don't think you can match all the Han mixed with Latin in any format.
