Question

How to fetch the columns in a single row in reverse order with PHPCassa?

Answer 1

Trick is done with empty column slice object.

...

$cf = new ColumnFamily($pool, 'mycolumnfamily');

// normal order
$rows = $cf->get('mykey'); 

print_r($rows);

// reverse order, 5 is column count, true is reverse order
$rows = $cf->get('mykey', new ColumnSlice(null, null, 5, true) );

print_r($rows);
