Deleting items from an array...?

[TheDXMaster]

Hey, i'm trying to code a shopping cart and need to enable a feature for the user to delete items from their shopping cart.

This is the essence of my cart.php:

if (isset($add)) {
$products_array[] = $add;
}

print "<br>";
foreach ($products_array as $id) {

	$result = mysql_query("select * from products where id = $id");
	while ($array = @mysql_fetch_array($result, MYSQL_ASSOC)) {
		  print "<b><u>".$array[name]."</u></b> | ";
		  print "<i>$".$array[price]."</i><br>";
		  print $array[description]."<br><br>";

		  }

}

print "<a href='productindex.php?PHPSESSID=".$sessid."'>Keep Shopping</a>";

Previously I tried something like this:

if (isset($delete)) {
foreach($products_array as $i) {
if ($i == $delete) {
$i = NULL;
}
}
}

What should I do? Thanks!

You could loop through whole array and create another one with values you'd like to keep...

or:
use array_diff function... See http://www.fi.php.net/manual/en/function.array-diff.php from more information.

Let's say that you'd like to remove "car1" and "flower2" from your array $items:
$items = array_diff ($items, array ("car1", "flower2"));
