The only way I can see to get a total record count necessary for setting up some sort of pagination mechanism would be something like:
$fileMakerObj = new FileMaker( /* credentials redacted */ );
$fc = $FileMakerObj->newFindCommand( someLayout );
//Get max Record count for someLayout
$fc->setRange(0,0);
$result1 = $fc->execute();
$maxRecords = $result1->getTableTotalCount();
$fc->clearRange();
//Window 0-100 of $maxRecords
$fc->setRange(0,100);
$page1 = $fc->execute();
//Repeat as necessary
Is there something I am missing, or is this the only solution?
