[resolved] split string to array, then foreach

[solitario]

Hello all.

I am posting a string, $_POST['hotels'], which is: "2,33,22,20,21"

I would like to split that string, at the comma, into an array, converting each to a number, then doing a foreach.

I was thinking:

$hotels = split(',',$_POST['hotels']);

foreach ($hotels as $x) {
	//convert $x to a number
	//do something with $x
}

But I'm not doing it right.
Any help is greatly appreciated.
Many thanks.

well, i am no wiz at php, but cant strings be used as a number value as well? i know CGI it is like that.

so couldnt you do a calculation like this:

$hotels = split(',',$_POST['hotels']);
echo $hotels."*5=";
$a = $hotels[0] * 4;
echo $a;

that should take the first array of $hotels and multiply it by 4 then echo the result.

Thanks (again) ALL. That works perfectly.
