I'm having a problem sorting my array and wondered if anybody had experience
sorting arrays by their values. What I need to do is resort the array below
where the most expensive product shipping price starts at position zero no
matter how big the array is.
array(2) {
[0] => array(48) {
["product_id"] => string(2) "34"
["product_name"] => string(29) "Bears Ball Cap"
["product_ordered_size"] => string(5) "ADULT"
["product_sales_price"] => string(8) "11.90"
["product_shipping_price"] => string(4) "7.85"
["product_shipping_extra"] => string(4) "0.06"
}
[1] => array(48) {
["product_id"] => string(2) "37"
["product_name"] => string(21) "Baldwin L Grand Piano"
["product_ordered_size"] => string(5) "Grand"
["product_sales_price"] => string(8) "11671.90"
["product_shipping_price"] => string(6) "500.00"
["product_shipping_extra"] => string(6) "450.00"
}
Thanks

Everything can be done with three custom lines of code, the rest is PHP
existing function calls.

Example #3 Sorting database results
I expanded your list below and randomly added some data... Anyways,
replace my $ar array definition with your array and you should be good
to go. One question though, is this coming from a DB? If so, why not
do the sorting in the SQL call instead of PHP? Just a thought.
