Question

I have a short code to get the results of a db_query into an array:

$r = db_query('SELECT vid FROM {node_revisions} WHERE nid = %d', $node->nid);
while ($vids[] = db_result($r));

The only problem is, that I get an empty array value:

Array(
   [] => 105
   [] => 409
   [] =>
)

How can I prevent the empty array value?

Answer 1

I found the shortest code to get all results from db_query in an array:

for ($vid; $vid = db_result($r); $vids[] = $vid);

The resulted array looks now like this:

Array(
   [0] => 105
   [1] => 409
)
