Since I have disabled mb support on my servers to get my 
scripts to work I cannot give a concrete example online but 
I can give something here.

My configure string is:
./configure --quiet --with-apxs=/usr/local/apache-1.3.26/
bin/apxs --with-ftp --with-mysql=/usr/local/mysql --with-
pgsql=/usr/local/pgsql --enable-track-vars --enable-
calendar --disable-debug --with-curl=/usr/local/curl --
enable-mbstring --enable-mbstr-enc-trans --with-mcrypt --
with-gd --with-png-dir --with-zlib-dir --with-jpeg-dir

a second server which also had this problem had a configure 
string of:
./configure --quiet --with-apxs=/usr/local/apache-1.3.26/
bin/apxs --with-ftp --with-mysql=/usr/local/mysql --enable-
track-vars --enable-calendar --disable-debug --with-curl=/
usr/local/curl --enable-mbstring --enable-mbstr-enc-trans

Create a form in which some of the form values consist of:

<input type="text" name="myvar[myvar1]">
<input type="text" name="myvar[myvar2]">
<input type="text" name="myvar[myvar3]">

Then submit the form somewhere and echo back 
$myvar['myvar1'], etc or even do a print_r().  You'll find 
(hopefully as i did) that the first four characters of each 
input are chopped off.

In my case the form field names were like this:

I've seen other forms do this successfully (not with the mb 
support compiled in) so I incorporated it into my shopping 
cart program. After adding the two parameters " --enable-
mbstring --enable-mbstr-enc-trans" submissions using this 
form had the first four characters chopped off.

Since this is so weird I don't know if it would have been 
caught before. I would love to see a solution to this since 
I need MB support for a PHP Domain Registrar program we're

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the original bug instead.

Thank you for your interest in PHP.
