removing items individually from an array

[almystersv]

Hi Guys I have this page that I am trying to use to remove one item at a time from the array.

 

At present it just competely empties the array.

 

Please help...

 

<?php
session_start();
foreach($_SESSION['basket'] as $key => $product) {
	if ($_SESSION['basket'][$key]['URN'] == $product['URN'])
	{
		unset($_SESSION['basket'][$key]);
	}
}
header("Location: StationaryMain.php");
exit();
?>

Well is the line below always true?

if ($_SESSION['basket'][$key]['URN'] == $product['URN'])

Do you want to unset the entire row?  Or just the "urn" key?  If you just want to unset the urn key try this:

 

unset($_SESSION['basket'][$key]['URN']);

no i would like to delete the entire row that matches that URN.

Im using it as a shopping cart example and need a remove function.

What youve got:

foreach($_SESSION['basket'] as $key => $product)
{
if ($_SESSION['basket'][$key]['URN'] == $product['URN'])
{
	unset($_SESSION['basket'][$key]);
}
}

 

What this tells me is that if x[y] == x[y] (albeit different names) then unset, and obviously it will unset everything because it's testing against itself!

Is that clear? You need to test it against something other than itself.
