I don't know how to convert ereg to preg_match

[Strikers]

I have a problem with this line in an AAC I am using.

Since I am using the latest version of Xampp it gives me a deprecated error on every ereg function on php.

I want to convert the ereg part on this code to a preg_match, but I don't know how.

 static public function ValidPassword($pass) {
        return strlen($pass) > 5 && strlen($pass) <= 50 && ereg('^[a-zA-Z0-9~!@#%&;,:\\\^\$\.\|\?\*\+\(\)]*$',$pass);
    }

I need to convert that to preg_match

ereg('^[a-zA-Z0-9~!@#%&;,:\\\^\$\.\|\?\*\+\(\)]*$',$pass);
