PHP: Pulling lowest values in multiple arrays -


i have 1 element of project holding me , try might have not been able work. can please assist me - sure confused , there easy answer. have 3 multi-dimensional arrays (3 different pricing data different companies), each holding sort of data:

[0] => array (     [itemcode] => 27663     [buy] => 50000     [perquantity] => 5 )  [1] => array (     [itemcode] => 38663     [buy] => 41000     [perquantity] => 4 )

the same itemcodes appear in data 3 companies. create html table has following columns data:

itemcode  | supplier1  | supplier2  | supplier3  | difference (2nd lowest minus lowest) 38663   | 12500  | 12425  |  16440  |  75

my question: there shortcut doing this, creating array temp store data? or there concept feel required complete easily?

any appreciated.

i don't know numbers in html table come from, think creating temporary array way go.

$items=array(); foreach ($supplier1 $data) {   $items[$data['itemcode']]['supplier1buy']  = $data['buy'];   $items[$data['itemcode']]['supplier1perq'] = $data['perquantity']; } foreach ($supplier2 $data) {   $items[$data['itemcode']]['supplier2buy']  = $data['buy'];   $items[$data['itemcode']]['supplier2perq'] = $data['perquantity']; } // etc.

to make prettier code, think i'd need know more how data works. example, don't know if need 'perquantity'. number in html table function of buy , perquantity?

once you've got large $items array, can walk through create rows of html table.
