PHP OOP: How to get database rows as objects? - php

Question

I can do this when selecting a single row fine but cant quite get my head around doing this for multiple rows of data.
For the single row I simply instantiate a new object that does a number of operations behind the scenes that bascially produces a row from the database as our object.
Example:
$object = new Classname($param);
foreach($object->row as $key=>$value) {
echo $key.":".$value."\n";
}
//output
id:1
firstname:steve
lastname:took
etc...
Any clever people here able to point me in the right direction please?
NOTE: just want to be able to create an object for each row rather than the one object with nested arrays
EDIT: sorry $object->row is a member of the class that stores selected row from the database

Answer 1

If I got you the answer is pretty simple mysql_fetch_object
Example:
while ($row = mysql_fetch_object($result)) {
echo $row->user_id;
echo $row->fullname;
}

Why don't you consider to use an ORM (Object Relational Mapper), like Doctrine or Propel?
I prefer Doctrine: http://www.doctrine-project.org/
Enjoy! :)

Here is an example
class users extends db {
public $users_id = 0;
public $users_group = 0;
public $users_firstname = 0;
public $users_lastname = 0;
public function open($id) {
if (is_numeric($id)) {
$sql = "SELECT * FROM users WHERE users_id = '$id'";
$res = parent::DB_SELECT($sql);
if (mysql_num_rows($res) <> 1) {
return 0;
}
} else {
$sql = "SELECT * FROM users " . $id;
$res = parent::DB_SELECT($sql);
if (mysql_num_rows($res) <= 0) {
return 0;
}
}
$data = array();
while ($row = mysql_fetch_array($res)) {
$this->users_id = $row['users_id'];
$this->users_group = $row['users_group'];
$this->users_firstname = $row['users_firstname'];
$this->users_lastname = $row['users_lastname'];
$data[] = (array) $this;
}
return $data;
}
public function setUsersId($users_id) { $this->users_id = addslashes($users_id); }
public function getUsersId() { return stripslashes($this->users_id); }
public function setUsersGroup($users_group) { $this->users_group = addslashes($users_group); }
public function getUsersGroup() { return stripslashes($this->users_group); }
public function setUsersFirstname($users_firstname) { $this->users_firstname = addslashes($users_firstname); }
public function getUsersFirstname() { return stripslashes($this->users_firstname); }
public function setUsersLastname($users_lastname) { $this->users_lastname = addslashes($users_lastname); }
public function getUsersLastname() { return stripslashes($this->users_lastname); }
}

You could use MySQLi.
// Connect
$db = new mysqli('host', 'user', 'password', 'db');
// Query
$users = $db->query('SELECT * from users');
// Loop
while($user = $users->fetch_object()) {
echo $users->field;
}
// Close
$users->close();
$db->close();
