Please help with 2D array

[2DQ]

$products_size_array = array(array('size' => '', 'sizecount' => ''));
$products_size_query = tep_db_query("select products_id, products_size, products_sizecount from " .  TABLE_PRODUCT_SIZE . " where products_id = '" . (int)$HTTP_GET_VARS['pID'] . "' order by products_size");

while ($products_size_detail = tep_db_fetch_array($products_size_query)) {
$products_size_array[] = array('size' => $products_size_detail['products_size'],
    'sizecount' => $products_size_detail['products_sizecount']
);
}

[b]so I have the array above called $products_size_array, each row has 2 elements: size and sizecount
How do I output the array like the following[/b]: 

size[0]/sizecount[0], size[1]/sizecount[1]

I have size 5 quantity is 3
I have size 6 quantity is 2

ex:  5/3, 6/2, .....

I tried this

<?
$count = count($products_size_array);
for ($i = 0; $i < $count; $i++) {
  echo $products_size_array['$i'] . ",";
}
?>

[b]All it outputs is[/b]:  ,,,
[b]With this code[/b]: <?php print_r($products_size_array); ?>
[b]I can see that the array does have values in it.  It outputs the below[/b]:
Array ( [0] => Array ( [size] => [sizecount] => ) [1] => Array ( [size] => 5 [sizecount] => 3 ) [2] => Array ( [size] => 6 [sizecount] => 2 ) )

[b]what am I doing wrong?[/b]

Your array has keys withthe names 'size' and 'sizecount' and in your loop you are trying to call them with 0 & 1.

Try this:
[code]
foreach ($products_size_array as $value) {
    echo "I have size $value[size] quantity is $value[sizecount]<br>";
}
[/code]

I did above and it outputs this

5 / 3
6 / 2
6 / 2
6 / 2
6 / 2


Which it shouldnt

there are only 2 sizes in the table
size 5 quantity 3
size 6 quantity 2

I dont know why its repeating 6/2

One problem is that the very first line from your first post is creating some un-needed indexes in the array. Change that to:

$products_size_array = array();

It was kind of hard to spot that the way that you had printed out the array data. Once you make that change, if you are still having the problem, try outputting the array like this so it is more readable:

echo "<pre>";
print_r($products_size_array);
echo "<pre>";

couldn't you use the array_unique() function to group similar arrays.

try
[code]
<?php
$product_size_array = array(
    array ('size' => 5, 'sizecount' => 2),
    array ('size' => 6, 'sizecount' => 3) 
);

foreach ($product_size_array as $data) {
    echo join ('/', $data) . '<br>';
} 
?>
[/code]
