[RESOLVED] numbers sum like strings

[foreach]

Hello,
I'm new at oop and i have a problem (although i think it is not an oop mistake but php)
Heres what i have:
Index.php:

<?php include("_classes.php"); error_reporting(E_ALL)?>
<?php
$family = new family;
$family->addPeople(2);
print_r ($family->showInfo()); 
?> 

and classes:

class family 
{	
	private $people = "0",
			$food = "0",
			$drink = "0",
			$money = "0",
			$data;
	public function showInfo()
	{
		$data = array('People'=>"$this->people",
						'Food'=>"$this->food",
						'Drink'=>"$this->drink",
						'Money'=>"$this->money"
						);
		return $data;

}
public function addPeople($mitu='1')
{
	$this->people.=(int)$mitu;
	return $this->showInfo();
}

} 
?>

The problem is that it gives me People count 02, not 2. Any help and comment will be appreciated.

When defining a variable you wish to hold an integer, you shouldn't use quotation marks.

$food = "0"

should be

$food = 0

This probably isn't the main problem, as you appear to be concatenating rather than adding:

$this->people.=(int)$mitu;

should be

$this->people+=(int)$mitu;

Hope that helps
