Providing an empty string is deprecated

Description

Calling ord() with an empty string is like calling it without an argument: it has nothing to work on.

Example

<?php

    ord('');

?>

Solutions

• Remove the call ord() on empty string.

• Check that the length of the string passed to ord() is 1.

• Ensure that the string is in latin1 encoding: multi-byte strings will also lead to an error.

Related Error Messages

• Providing a string that is not one byte long is deprecated. Use ord($str[0]) instead
