Answer 1

Give this a shot:

$id = mysql_real_escape_string(31);
$result = mysql_query('SELECT * FROM `users` where `id` = ' . $id . ' LIMIT 1');

$row = mysql_fetch_assoc($result);

echo $row['id']; // 31
echo $row['name']; // name
// etc..

// If you wanted to output ALL the fields you could loop through
foreach($row as $field_name => $value) {
  echo $field_name . ': ' . $value . '<br />';
}

// The output would look something like
// id: 31
// name: John Smith
// ...
