php very useful mysql connect function for small project

This class is very useful for small projects, it easy and fast to connect mysql with php script. Thank you Ciprian Mocanu to provide this document. The Class:

$result = $m->query('SELECT * FROM `users`');

//this will output an array like this: $array[$count][$table][$field]
 
//simple execute command (I recommend using the delete and the insert and the update methods of the class)
$result = $m->execute('DELETE FROM `pages` WHERE `id`=5');
var_dump($result); //returns true if ok and false if not
 
//method to select (clean and beautiful)
$result = $m->select(array(
	'table' => 'users',
	'condition' => 'active=1 AND type=1'

var_dump($result);
// Will output something like this:
