How to merge multiple dimension array cakephp with two key - php

Question

I just using function query() of cakePhp. The query will return array something like :
array(
(int) 0 => array(
'cate' => array(
'date' => '2016-12-05',
),
'cate_detail' => array(
'rel_data_category' => '11'
),
'cate_item' => array(
'price' => '150.000'
),
'item' => array(
'code' => '1'
)
),
(int) 1 => array(
'cate' => array(
'date' => '2016-12-05',
),
'cate_detail' => array(
'rel_data_category' => '10'
),
'cate_item' => array(
'price' => '250.000'
),
'item' => array(
'code' => '1'
)
),
(int) 2 => array(
'cate' => array(
'date' => '2016-12-06',
),
'cate_detail' => array(
'rel_data_category' => '10'
),
'cate_item' => array(
'price' => '250.000'
),
'item' => array(
'code' => '2'
)
),
(int) 3 => array(
'cate' => array(
'date' => '2016-12-06',
),
'cate_detail' => array(
'rel_data_category' => '10'
),
'cate_item' => array(
'price' => '250.000'
),
'item' => array(
'code' => '1'
)
)
)
Now, I want to check if array have the same cate.date and item.code will merge array (in this case is elements 0,1 of my array). Output something like :
array(
(int) 0 => array(
'cate' => array(
'date' => '2016-12-05',
),
'cate_detail' => array(
(int) 0 => array (
'rel_data_category' => '11',
'price' => '150.000'
),
(int) 1 => array(
'rel_data_category' => '10',
'price' => '250.000'
)
),
'item' => array(
'code' => '1'
)
),
(int) 1 => array(
'cate' => array(
'date' => '2016-12-06',
),
'cate_detail' => array(
(int) 0 => array (
'rel_data_category' => '10'
'price' => '250.000'
)
),
'item' => array(
'code' => '2'
)
),
(int) 2 => array(
'cate' => array(
'date' => '2016-12-06',
),
'cate_detail' => array(
(int) 0 => array (
'rel_data_category' => '10'
'price' => '250.000'
)
),
'item' => array(
'code' => '1'
)
)
)
Please help!

Answer 1

To do that
First declare a variable which later you will store new merge array data
$filter_data = array();
then loop your existing array
foreach($items as $item) {
// do somethind
then create a function which check if item which same date and code not yet exist in the new array
// checker
if (!checkExist($item['cate']['date'], $item['item']['code'])) {
Create a variable for temporary data that will append to the new array later
$data = array(
'cate' => $item['cate'],
'item' => $item['item']
);
Then create loop again which will append all index item cate_detail and cate_item who have the same
date and code from the parent loop
}
}
So your code would be like this
$items = array(
(int) 0 => array(
'cate' => array(
'date' => '2016-12-05',
),
'cate_detail' => array(
'rel_data_category' => '11'
),
'cate_item' => array(
'price' => '150.000'
),
'item' => array(
'code' => '1'
)
),
(int) 1 => array(
'cate' => array(
'date' => '2016-12-05',
),
'cate_detail' => array(
'rel_data_category' => '10'
),
'cate_item' => array(
'price' => '250.000'
),
'item' => array(
'code' => '1'
)
),
(int) 2 => array(
'cate' => array(
'date' => '2016-12-06',
),
'cate_detail' => array(
'rel_data_category' => '10'
),
'cate_item' => array(
'price' => '250.000'
),
'item' => array(
'code' => '2'
)
),
(int) 3 => array(
'cate' => array(
'date' => '2016-12-06',
),
'cate_detail' => array(
'rel_data_category' => '10'
),
'cate_item' => array(
'price' => '250.000'
),
'item' => array(
'code' => '1'
)
)
);
$filter_data = array();
foreach($items as $item) {
if (!checkExist($item['cate']['date'], $item['item']['code'])) {
$data = array(
'cate' => $item['cate'],
'item' => $item['item']
);
foreach($items as $detail) {
if ($detail['cate']['date'] == $item['cate']['date'] &&
$detail['item']['code'] == $item['item']['code']) {
$data['cate_detail'][] = array(
'rel_data_category' => $detail['cate_detail']['rel_data_category'],
'price' => $detail['cate_item']['price']
);
}
}
$filter_data[] = $data;
}
}
function checkExist($date, $code){
global $filter_data;
foreach($filter_data as $data) {
if ($data['cate']['date'] == $date &&
$data['item']['code'] == $code) {
return true;
}
}
return false;
}
pr($filter_data);
