PHP “backspace” character during output possible?

Question

I have a feeling the answer is \"it\'s not possible,\" but thought I\'d ask to satisfy my curiosity.

I have some code that\'s echoed where the \\n is unavoidable:

Yes, the backspace character is ASCII character code 8 (According to the ASCII table), so you can output it in php using chr(). eg:

echo 'ab' . chr(8);

will output "a"
