That is strange, because $rows should always be an array, if no
references are found it should just be an empty array.

The only condition in which t3lib_db::exec_SELECTgetRows() does *not*
return an array is if there was a sql error. If that is the case, this
should be fixed instead of moving the foreach().

Could you please debug why $rows was not an array in your case?

-1 as count($rows) only works properly on a arrays, too.

cheers,
