[FX.php List] A nagging question: Foreach

[Bob Patin]

Leo,

I use it when I'm pulling data from a single record, like this:

foreach($findResult['data'] as $key => $value);
$field1 = $value['field1'][0];
$field2 = $value['field2'][0];
$field3 = $value['field3'][0];

... and so on. There's no need for a looping structure since your  
foundset only has a single record. I use it all the time...

Also, you can use that same method if you want to retrieve the last  
record in the foundset. Opposite to FileMaker, which always shows you  
the first record in a foundset after a FIND, this method returns the  
last record.

So if you get 10 records returned, and use that method above, you'll  
retrieve the values in the last record of the foundset, based on the  
sort rules you may have used.
