php and oracle

[Anon]

i have a syntax like this:

$sql = "select * from login_user where id_user='$user'";
$query = OCIParse($conn,$sql);
OCIExecute($query);

i can't make 2 sentences like this:
<to get number rows>

$number = OCIFetchStatement($sql,$res);

with :
<to get all records>
OCIFetchInto($sql, &$results)

if i want to get both number rows and all records with 1 operation select,what should i do???

thx
