New Comment:
Are you using the "mb" extension? i.e. did you compile it to enable
multi-byte support? If so, you (or your ISP) need to get the latest
"mbstring.c" file from the CVS and recompile and reinstall. The
problem lies in mbstring.c and it has been fixed by its author.

This bug is not restricted to checkbox's! I think it applies to all
input types.. The following example is a modification of the first test
script but using text inputs. I asked my ISP to apply the recommended
recompile config but it didn't work! PLEASE HELP

This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.
Already fixed, recompile --without-mb-str-enc (or simlilar) to make
this go away with 4.2.3.

When checkboxes are used in a form with arrays (e.g. name=something[])
values retrieved from the resulting $_POST[something] array are
trunacted. In fact, the first 4 bytes are truncated.
If values are POSTED one by one, i.e. not via an array, things seem to
work.
The same script used to work on 4.2.2. I discovered this problem after
upgrading to 4.2.3
