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

RTFM:

http://www.php.net/manual/en/function.preg-replace.php

"When using the e modifier, this function escapes some characters 
(namely ', ", \ and NULL) in the strings that replace the 
backreferences"
