Array driving me loop(y) - php

Question

Pardon the pun in my title (heh) but this is seriously driving me nuts!
This is my code:
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
echo '<pre>';
print_r($total);
echo '</pre>';
}
...It outputs the following:
Array
(
[#attributes] => Array
(
[type] => Subtotal
[name] => Subtotal
)
[0] => 299.99
)
Array
(
[#attributes] => Array
(
[type] => Shipping
[name] => Shipping
)
[0] => 13.36
)
Array
(
[#attributes] => Array
(
[type] => Tax
[name] => Tax
)
[0] => 0.00
)
Array
(
[#attributes] => Array
(
[type] => GiftCertificate
[name] => Gift certificate discount (117943:#CAC7HXPXFUNNJ3MTGC:63.35 117372:#DK9T9TMTCTCTUWF9GC:250.00)
)
[0] => -313.35
)
Array
(
[#attributes] => Array
(
[type] => Total
[name] => Total
)
[0] => 0.00
)
My question is: how do I save each dollar amount [0] into a respective variable named according to the array['type']?

Answer 1

Rather than a variable (which could be done with variable variables), I recommend putting them into an array $prices, keyed by the type attributes.
$prices = array();
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
echo '<pre>';
print_r($total);
echo '</pre>';
// Append the price to an array using its type attribute as the
// new array key
$prices[$total['#attributes']['type']] = $total[0];
}
Untested, of course, but I believe it will do the job.

Answer 2

$var[] = array('type' => $total['#attributes']['type'], 'amount' => $total[0])

Answer 3

Something like this maybe?
$total_amount_by_type = array();
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
$total_amount_by_type[$total->type] = $total[0]
}

Answer 4

Are you looking for something like this:
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
// will create variables $Tax, $GiftCertificate etc
${$total['#attributes']['type']} = $total[0];
echo '<pre>';
print_r($total);
echo '</pre>';
}
