How to load MySQLi result set into two-dimensional array?

Question

I\'ve got a problem with the mysqli result set. I have a table that contains a bunch of messages. Every table row represents one message. I have a few columns like ID, title

Answer 1

You're almost there, you would only need to change a few things:

$result = $link->query("SELECT * FROM messages WHERE public = '1'");
$messages = array();
while($message = $result->fetch_assoc()){
   $messages[] = $message;
}

This would result in something like this:

array(
  0 => array('message' => ..., 'subject' => ...), 
  1 => array('message' => ..., 'subject' => ...), 
  2 => array('message' => ..., 'subject' => ...), 
);

If you want the IDs as the keys, do something like this:

$messages = array();
while($message = $result->fetch_assoc()){
   $messages[ $message["id"] ] = $message;
}

Which would result in:

array(
  123 => array('message' => ..., 'subject' => ...), 
  456 => array('message' => ..., 'subject' => ...), 
  789 => array('message' => ..., 'subject' => ...), 
);

In PHP 5.3, you also get a new method, which does the same as the first code example I posted:

$messages = $result->fetch_all(MYSQLI_ASSOC);

Answer 2

If i get you right, you want to achieve something that is produced by:

$result = $link->query("SELECT * FROM messages WHERE public = '1'");

$messages = array();
while($singleMessage = $result->fetch_assoc()){
  $messages[$singleMessage]['title'] = $singleMessage['title'];
  $messages[$singleMessage]['body'] = $singleMessage['body'];
}

This will get you an 2 dimensional array, using the ID as key.

How your final array must look like?

Try this:

$result = $link->query("SELECT title, body FROM messages WHERE public = '1'");
$array = array();
while ($array[] = mysql_fetch_assoc($result)) {}
