Answer 1

You can use the PHP function usort like this:
function sortInnerPrice($a, $b) {
if ($a['price'] == $b['price']) {
return 0;
}
return ($a['price'] < $b['price']) ? -1 : 1;
}
// First sort the inner prices
foreach ($test as $key => $val) {
usort($test[$key]['solutions'], 'sortInnerPrice');
}
function cmp($a, $b)
{
$aPrice = $a['solutions'][0]['price'];
$bPrice = $b['solutions'][0]['price'];
if ($aPrice == $bPrice) {
return 0;
}
return ($aPrice < $bPrice) ? -1 : 1;
}
// Then sort by lowest solution price
usort($yourArray, "cmp");
usort is a PHP function that allows you to sort an array based on whatever you want. You create a function that will return 0 if they are the same, -1 if you want $a before $b, and 1 if you want $a after $b.

Answer 2

Try to make another array containing all the prices and then use array_multisort for it
