PHP filter★And other special characters

There are many ways to filter special symbols. The following describes how to use regular expressions to implement them. I hope this will be helpful to you. The code is as follows:

If (preg_match ("/['.,:;*?~ '! @ # $ % ^ & + =) (<>{}] |\] | \ [|\/ |\\| \ "|\| /", $ User )){
Echo 'Do not enclose some special characters in the name. please only use letters, numbers, and Chinese characters. of course, you must select simplified Chinese GB2312 in your browser, do not select traditional Chinese or Chinese HZ. Come back and wait for you! ';
Exit ();
}
