Description:
------------
I'm not 100% sure if this is a bug, or just a 'quirk', but my attempt to get feedback on this issue on the php db support list was unsuccessful.  So, here I am....

I am selecting multiple columns from a table, one being a clob.  the query returns multiple records for the query.  The results are all good, execpt the clob column in certain circumstances.  

Normally, with such a db return, I would loop through the results and grab the clobs one by one.  Under 'special' circumstances, I would want to first loop throught the results and assign the results to a new array before fetching the clob.  This is where things get funky.  In this senario, the last returned record's clob column overwrites all previous clob columns (all the previous records have there unique data, except the clob columns which contains the data for the last record across all previous records).


A working example:


$query = 'select 
                id,
                author,
                cdate,
                views,
                title,
                message,
                top
            from 
                APP_THREADS 
            where 
                TYPE = \'D\'';
$stmt = ociparse($fw_db->connection, $query);
ociexecute($stmt);

while (OCIFetchInto ($stmt, $row, OCI_ASSOC)) {
    echo $row['MESSAGE']->load();
    echo $row['id'];
    // etc....
}


as expected, I get all clobs from the result set.  But in this example, I do not:


$query = 'select 
                id,
                author,
                cdate,
                views,
                title,
                message,
                top
            from 
                APP_THREADS 
            where 
                TYPE = \'D\'';

$stmt = ociparse($fw_db->connection, $query);
ociexecute($stmt);

while (OCIFetchInto ($stmt, $row, OCI_ASSOC)) {
    // assign all lob resources to array for later loading
    $messages[] = $row['MESSAGE'];
}

foreach ($messages as $message) {
    echo $message->load();
}


In this example, the last assigned lob resource overwrites all previous lob resources.  When fetching the clob content later on, each record returns the data from the last lob.  

I am pretty unawair of the internal mechanics of how resources are handled, and this just might be a quirk of how db result resources for oci8 are handled, and is unavoidable.  (it looks like one resource is returned for all lobs, not multiple resources for each lob).

However, it is a pretty counter intuitive 'quirk'.  If I can loop through the results and assign all non resource elements to an array for later operations, should I not be able to do the same thing with resources?


Thanks.
