With var_dump I immediately found the mistake. It was a "column"=>NULL which caused the error. Now everthing is working fine. Obviously var_dump() isn't described in the manual (why?): 15:17:35 (martin@tutnix):~ $ grep -r var_dump /usr/local/doc/php4/manual /usr/local/doc/php4/manual/function.getimagesize.html: var_dump($iptc); /usr/local/doc/php4/manual/function.ocibindbyname.html: var_dump($arr); /usr/local/doc/php4/manual/function.ocinewcursor.html: var_dump($data); Sorry, I left some lines of code out. $array3 was passed to a function, hence the name $values_array.
