If you think you have found a bug in PHP, please report it. The
PHP developers probably don't know about it, and unless you
report it, chances are it won't be fixed. You can report bugs
using the bug-tracking system at http://bugs.php.net/. Please do not
send bug reports in mailing list or personal letters. The
bug system is also suitable to submit feature requests.
Read the How to report a bug
document before submitting any bug reports!
