This is not a direct answer to his exact question, but to what the title seems to allude to: outputting a PHP "backspace" character, which is probably only useful when using the PHP CLI.

You can find the right ASCII code for this (and other characters) on the ASCII table, and then use either chr() or an escape sequence:

echo chr(8);
echo "\010";
