You should investigate, why $iBookeyBy is undefined.  It is always
preferable to initialize a variable explicitely before you use it.  This
is particularly important for PHP due to the dangerous register_globals
option (which was fortunately removed since PHP 5.4).  If this is
enabled (what should never be), the code may be vulnerable.  Checking
for isset($iBookeyBy) won't help in this case.
