When I try to use chr ( "0x03" ) with PHP 7.1.15 I get an error message "A non well formed numeric value encountered", why do I get this message?

Because `chr` takes an integer and you are passing a string. – AbraCadaver Mar 12 '18 at 19:34
Use `chr(0x03)`. See: http://php.net/manual/en/language.types.integer.php – Sammitch Mar 12 '18 at 19:45
