Question

The function I have is below and the output of it.

$results = mysql_query("SELECT * FROM tmsessions WHERE session_user_id ='".$_SESSION['user_id']."'");

    $count = mysql_num_rows($results);
    $username = mysql_fetch_assoc(mysql_query("SELECT user_fname FROM tmusers WHERE user_id = '".$_SESSION['user_id']."'"));

    $json_data = array( 'userID'=>$_SESSION['user_id'], 'userName'=>$username['user_fname'], 'total'=>$count );

    while($session = mysql_fetch_assoc($results))
    {
        $numListItems = mysql_num_rows(mysql_query("SELECT session_id, listing_unique_id FROM tmdata WHERE session_id = '".$session['session_id']."'"));

        $listItems = array('sessionID'=>$session['session_id'],
                           'sessionName'=>$session['session_name'],
                           'sessionCount'=>$numListItems,
                           'sessionDC'=>date('h:iA - M m y',strtotime($session['session_date_created'])),
                           'sessionDM'=>date('h:iA - M m y',strtotime($session['session_date_modified'])),
                           'sessionActive'=>$session['session_active']);

        array_push($json_data, $listItems);

    }

    return json_encode($json_data);

Which outouts:

{"0":
{"sessionID":"9",
 "sessionName":"dataName0",
 "sessionCount":100,
 "sessionDC":"12:11AM - Jun 06 11",
 "sessionDM":"01:00AM - Jan 01 70",
 "sessionActive":"1"},
 "1":
{"sessionID":"10",
 "sessionName":"dataName1",
 "sessionCount":100,
 "sessionDC":"05:04PM - Jun 06 11",
 "sessionDM":"01:00AM - Jan 01 70",
 "sessionActive":"1"},
 "userID":"1",
 "userName":"Ezra",
 "total":2}

I need the “0”: and “1”: bits to become “listItem”: of each new associative array, but I don’t know howto manipulate the arrays correctly to get that :(.

Answer 1

In PHP, indexed and associative arrays are handled as the same type (i.e. matrices or one-dimensional arrays, a[0], a[1], … a[N], vs a[‘one’], a[‘two’], … a[‘something’]).

When using array_push() you are not creating or adding to an associative hash, but an indexed value to the end of the array.

Instead of using the array_push() function, you could do a direct assignment with a name of your choice, e.g.

$listItems[$session['session_id']] = array('sessionID'=>$session['session_id'],
                           'sessionName'=>$session['session_name'],
                           'sessionCount'=>$numListItems,
                           'sessionDC'=>date('h:iA - M m y',strtotime($session['session_date_created'])),
                           'sessionDM'=>date('h:iA - M m y',strtotime($session['session_date_modified'])),
                           'sessionActive'=>$session['session_active']);
