@NogDogOct 24.2005 — #One way:
Counting an item – multidimensional array
I’m still kinda new at this, but I have a multidimensional array (I think). It is an array that has arrays inside it. The inside arrays all have the same structure, (qty, product, color, size). How do I count how many items are ‘White’ * qty? I looked into the php manual and found array_count_values but others say it doesn’t work with MD arrays. ?

<?
$data = array(array('qty' => 1,
'product' => 'product1',
'color' => 'white',
'size' => 'L'),
array('qty' => 1,
'product' => 'product2',
'color' => 'red',
'size' => 'S'),
array('qty' => 2,
'product' => 'product3',
'color' => 'white',
'size' => 'M'),
array('qty' => 2,
'product' => 'product4',
'color' => 'blue',
'size' => 'XL'),
array('qty' => 3,
'product' => 'product5',
'color' => 'white',
'size' => 'M'));
# get total quantity of white-colored items:
$count = 0;
foreach($data as $item)
{
if($item['color'] == 'white')
{
$count += $item['qty'];
}
}
echo "<p>Total: $count</p>n";
