Get the index number in an array

[toyfruit]

Hi all, I can't seem to work out how to get the index number from a session array. Could someone quickly show me how to do this.

I basically want to create a series of 'delete' links for a shopping cart. Each link should delete the specific item from the session array, but I can't seem to identify the unique index number in the array when the foreach loop runs:

 

My current code:

 

<?php
// display the delete links for each item in the basket
foreach ($_SESSION['cart']['item'] as $item_del){
	// show the remove button and set it to remove this item
	echo "<a href='cart.php?action=delete&cat_id=" . $cat_id . "&del_id=" . $item_del . "' target='_self'>delete</a><br />";
// used to see the array index number - not working at the moment
	echo $item_del;
}	
?>

Hi,

 

Check the associative array.

echo '<pre>';

print_r($_SESSION);

 

and correct the order either print your session array so one can suggest you the correct way to do the same.

 

Thanks

Foreach can return the key as well as the value, us the following syntax

foeach($array as $key => $value)
