Search through an array with two values - php

Question

Good day,
I'm trying to search through an array.
I have two IDs (productId, secondaryProductId) in an array ($package) with some other data:
array (size=7)
'title' => string 'Compleet' (length=8)
'productId' => string '102' (length=5)
'price' => string '45.75' (length=5)
'secondaryProductId' => string '150' (length=5)
'secondaryPrice' => string '58.75' (length=5)
I have an array with arrays ($availableProducts):
array (size=2)
0 =>
array (size=3)
'product_id' => int 102
'description' => string 'some description for 102'
'order_link' => string 'some/link/102'
1 =>
array (size=3)
'product_id' => int 150
'description' => string 'some description for 150'
'order_link' => string 'some/link/150'
2 =>
array (size=3)
'product_id' => int 160
'description' => string 'some description for 160'
'order_link' => string 'some/link/160'
3 =>
array (size=3)
'product_id' => int 140
'description' => string 'some description for 140'
'order_link' => string 'some/link/140'
What I want to achieve is to search both product IDs in the $availableProducts array.
If they exists (like 102 and 150 with there description and link exist) I want the description and link to be set in the first array where both the product IDs are.
Like this:
array (size=7)
'title' => string 'Complete' (length=8)
'productId' => string '102' (length=5)
'price' => string '45.75' (length=5)
'secondaryProductId' => string '150'
'secondaryPrice' => string '58.75'
'description' => string 'some description for 102'
'order_link' => string 'link/for/102'
'secondaryDescription' => string 'some description for 150'
'secondaryOrder_link' => string 'some/link/150'
If one of them doesn't exist I want it's ID and price to either be removed or set as an empty string (doesn't matter).
Like this:
array (size=7)
'title' => string 'Complete' (length=8)
'productId' => string '102' (length=5)
'price' => string '45.75' (length=5)
'secondaryProductId' => string ''
'secondaryPrice' => string ''
'description' => string 'some description for 102'
'order_link' => string 'link/for/102'
What I have tried so far with a foreach loop:
$finalArray = array();
foreach ($availableProducts as $product) {
if ($package['productId'] == $product->product_id) {
$package['orderLink'] = $product->order_link;
$finalArray[] = $package;
}
if ($package['secondaryProductId'] == $product->product_id) {
$package['secondaryOrderLink'] = $product->order_link;
$finalArray[] = $package;
}
}
But it doesn't work. At first it looks fine to set the orderLink, but then it kind of runs double:
array (size=2)
0 =>
array (size=5)
'productId' => string '102' (length=5)
'price' => string '35.75' (length=5)
'secondaryProductId' => string '150' (length=5)
'secondaryPrice' => string '48.75' (length=5)
'orderLink' => string 'link/for/102'
1 =>
array (size=6)
'productId' => string '102' (length=5)
'price' => string '35.75' (length=5)
'secondaryProductId' => string '150' (length=5)
'secondaryPrice' => string '48.75' (length=5)
'orderLink' => string 'link/for/102'
'secondaryOrderLink' => string 'link/for/150'
I've tried playing around a bit, also tried in_array. But I clearly do something wrong. Any help will be highly appreciated.

Here you go (truncated version)
$availableProducts = [
0 => [
'product_id' => 102,
'description' => 'some description for 102',
'order_link' => 'some/link/102',
], 1 => [
'product_id' => 150,
'description' => 'some description for 150',
'order_link' => 'some/link/150'
], 2 => [
'product_id' => 160,
'description' => 'some description for 160',
'order_link' => 'some/link/160'
]
];
$array1 = [
'title' => 'Compleet',
'productId' => '102',
'price' => '45.75',
'secondaryProductId' => '150',
'secondaryPrice' => '58.75',
];
print_r(
array_intersect_key(
array_column($availableProducts, null, 'product_id'),
array_flip([$array1['productId'], $array1['secondaryProductId']])
)
);
Output
Array
(
[102] => Array
(
[product_id] => 102
[description] => some description for 102
[order_link] => some/link/102
)
[150] => Array
(
[product_id] => 150
[description] => some description for 150
[order_link] => some/link/150
)
)

note - this only works if product_id is unique in $availableProducts
Basically array_column($availableProducts, null, 'product_id') will restructure your array using product_id as the key (no duplicate ids), then you can get the intersection between this and an array with the 2 id's you need to find. I filped it because I am to lazy to make them as keys, which they need to be for array_intersect_key (obviously) to work.
array_column - is extremely powerful for array to array comparison. There are several neat tricks you can do with it...
The above shows you how to filter out only the 2 you want, But if you just want to update the original array ($array1 in this example) is a simple matter of doing this:
$res = array_column($availableProducts, null, 'product_id');
$array1['productId'] = $res[$array1['productId']]['description'];
$array1['secondaryProductId'] = $res[$array1['secondaryProductId']]['description'];
Output
Array
(
[title] => Compleet
[productId] => some description for 102
[price] => 45.75
[secondaryProductId] => some description for 150
[secondaryPrice] => 58.75
)

See with the product ID's as the keys (see output from example one) we can just use the value to get that segment of the multi-dimensional array by it's product_id - directly.
Obviously it's pretty easy to do this too now
$res = array_column($availableProducts, null, 'product_id');
$array1['productId'] =['description' => $res[$array1['productId']]['description'], 'order_link' => $res[$array1['productId']]['order_link']];
$array1['secondaryProductId'] =['description' => $res[$array1['secondaryProductId']]['description'], 'order_link' => $res[$array1['secondaryProductId']]['order_link']];
Output:
Array
(
[title] => Compleet
[productId] => Array
(
[description] => some description for 102
[order_link] => some/link/102
)
[price] => 45.75
[secondaryProductId] => Array
(
[description] => some description for 150
[order_link] => some/link/150
)
[secondaryPrice] => 58.75
)
I'm not sure what you want as the end result, but maybe this will help you.
Enjoy
