Quick question (counting the values in an array?)

[Solarpitch]

Hey,

Yeah, I was just wondering how you count the values in an array.

if I use
[code]
count($_SESSION['quickpick']);

//this gives me "0123456789101112" instead of just "12"
[/code]

Any reason for this or is that just the way its done?

There's no way at all for us to know exactly what you're doing without knowing how you are setting up your session. It looks like you're retrieving the values for some reason instead.

Here's a quick idea of the structure of the session if it helps.

[code]
$_SESSION['quickpick'][] = $_GET['ID'];


http://www.myurl.com/save_quickpick.php?ID=53 <- button

<a href="http://www.myurl.com/save_quickpick.php?ID=53"><img src="..." border=0></a>




for ($i = 0; $i < count($_SESSION['quickpick']); $i++) {

$sql = "SELECT ID FROM database WHERE ID='" . $_SESSION['quickpick'][$i] . "'";
$result = $db->query($sql);
if ($row = $db->fetchrow($reslult)) {
// found ID
} else {
// id not found
}
}
[/code]

The code you've got is correct, to count the number of elements in an array then just use count().

[code=php:0]$total = count($_SESSION['quickpick']);[/code]

Or did you mean you want the total of all the elements in an array added together?
