[FX.php List] [TIP] - use groupsize = 0 to speed summaries

[DC]

Here's a tip for super-speeding up your code... when all you need is  
a count for a found set you can send zero as the groupsize parameter  
and speed up processing. this works because FX won't have any record  
data to parse from XML into arrays.

NOTE: this **only** applies to FX code where you want to get the  
foundCount only - for instance, in a summary. the data array item  
will be empty.

// retrieve zero records when all you need is the found count
$fx_object = new FX ($IP, $port);
// put zero in the groupsize parameter
$fx_object->SetDBData($db, $layout, 0);
$res = $fx_object -> FMFind();
$count = $res['foundCount'];
echo $count;

i use this technique to build summary tables where i don't care what  
the actual data is; i just want the counts.

enjoy.
