Description:
------------
Example says:
echo "12" ^ "9"; // Outputs the Backspace character (ascii 8)
                 // ('1' (ascii 49)) ^ ('9' (ascii 57)) = #8

the "12" should be "1"

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

why?
49 is bin 110001
58 is bin 111001

110001 ^ 111001 = 001000 = ascii 8 = the backspace character.
