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.
