I want create factors for each shops. How can I do? How can I known these items in basket are for one shop or has for 2 or 3 shop . How can separate this items to factor.
Array('customer' => Array('basket' => Array(
'9_2' => Array
(
"row" => "0",
'item' => 'cd',
'count' => '1',
'sale_start_date' => '1391-12-25 19:27:56',
'sale_end_date' => '1392-04-20 19:27:49',
'sale_price' => '40500',
'price' => '54564',
'id' => '999035',
'shopid' => '4'
),
'999_17' => Array
(
'row' => '1',
'item' => 'car',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '6'
),
'9_3' => Array
(
'row' => '2',
'item' => 'book',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '4'
),
'10_5' => Array
(
'row' => '2',
'item' => 'dvd',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '5'
)
)
)
);
This example is array from my SESSION . I want seperate factor with shopid value. In this basket for example we have 2 item from shopid=4 and have 1 item from shopid=6 and one item from shopid=5 how can create seprate factor for each shop.
First I use usort function for sort array with shopid but I can't continue for separate each same and not same item shop for create factor

Answer 1

Something like this should work
<?php
$shopItems = array();
foreach ($_SESSION['customer']['basket'] as $basket) {
$key = $basket['shopid'];
$shopItems[$key][] = $basket;
}
This will store groups of items from the same shop id in elements of the array $shopItems
For example (only showing shop id 4)
Array (
[4] => Array (
[0] => array(
"row" => "0",
'item' => 'cd',
'count' => '1',
'sale_start_date' => '1391-12-25 19:27:56',
'sale_end_date' => '1392-04-20 19:27:49',
'sale_price' => '40500',
'price' => '54564',
'id' => '999035',
'shopid' => '4'
),
[1] => array(
'row' => '2',
'item' => 'book',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '4'
)
)
)

Answer 2

$basket = array();
foreach ($_SESSION['customer']['basket'] as $k => $v)
$basket[$v['shopid']][$k] = $v;
print_r($basket);
Result:
Array
(
[4] => Array
(
[9_2] => Array
(
[row] => 0
[item] => cd
[count] => 1
[sale_start_date] => 1391-12-25 19:27:56
[sale_end_date] => 1392-04-20 19:27:49
[sale_price] => 40500
[price] => 54564
[id] => 999035
[shopid] => 4
)
[9_3] => Array
(
[row] => 2
[item] => book
[count] => 1
[sale_start_date] => 0000-00-00 00:00:00
[sale_end_date] => 0000-00-00 00:00:00
[sale_price] => 0
[price] => 520000
[id] => 999039
[code] => b125nh
[shopid] => 4
)
)
[6] => Array
(
[999_17] => Array
(
[row] => 1
[item] => car
[count] => 1
[sale_start_date] => 0000-00-00 00:00:00
[sale_end_date] => 0000-00-00 00:00:00
[sale_price] => 0
[price] => 520000
[id] => 999039
[code] => b125nh
[shopid] => 6
)
)
[5] => Array
(
[10_5] => Array
(
[row] => 2
[item] => dvd
[count] => 1
[sale_start_date] => 0000-00-00 00:00:00
[sale_end_date] => 0000-00-00 00:00:00
[sale_price] => 0
[price] => 520000
[id] => 999039
[code] => b125nh
[shopid] => 5
)
)
)

Answer 3

This should do the trick.
function get_seperated_shops($all_items)
{
$seperated_shops = array();
foreach($all_items AS $item => $properties)
{
$seperated_shops[$properties['shopid']][$item] = $properties;
}
return $seperated_shops;
}
echo "<pre>";
print_r(get_seperated_shops($_SESSION['customer']['basket']));
echo "</pre>";
