Description:
------------
When executing the query below, I get the wrong result. Although the database returns a integer, PHP treats it as a string. 

Here the relevant part of phpinfo():

MysqlI Support	enabled
Client API library version 	5.0.27
Client API header version 	5.0.27
MYSQLI_SOCKET 	/tmp/mysql.sock

The version of the MySQL server is 5.0.27

Reproduce code:
---------------
<pre>
<?php
$rDB = mysqli_connect('localhost', 'user', 'password', 'db');
mysqli_select_db($rDB, 'db');

$rResult = mysqli_query($rDB, 'SELECT id FROM producten WHERE id = 4472');

var_dump(mysqli_fetch_array($rResult));

echo "\n---\n";

var_dump(mysqli_fetch_field($rResult));

?>
</pre>

Expected result:
----------------
array(2) {
  [0]=>
  int(4) "4472"
  ["id"]=>
  int(4) "4472"
}

---
object(stdClass)#3 (11) {
  ["name"]=>
  string(2) "id"
  ["orgname"]=>
  string(2) "id"
  ["table"]=>
  string(9) "producten"
  ["orgtable"]=>
  string(9) "producten"
  ["def"]=>
  string(0) ""
  ["max_length"]=>
  int(4)
  ["length"]=>
  int(11)
  ["charsetnr"]=>
  int(63)
  ["flags"]=>
  int(49699)
  ["type"]=>
  int(3)
  ["decimals"]=>
  int(0)
}

Actual result:
--------------
array(2) {
  [0]=>
  string(4) "4472"
  ["id"]=>
  string(4) "4472"
}

---
object(stdClass)#3 (11) {
  ["name"]=>
  string(2) "id"
  ["orgname"]=>
  string(2) "id"
  ["table"]=>
  string(9) "producten"
  ["orgtable"]=>
  string(9) "producten"
  ["def"]=>
  string(0) ""
  ["max_length"]=>
  int(4)
  ["length"]=>
  int(11)
  ["charsetnr"]=>
  int(63)
  ["flags"]=>
  int(49699)
  ["type"]=>
  int(3)
  ["decimals"]=>
  int(0)
}
