PHP: How can I have an array with same keys? - php

I have 2 arrays $projectsIds = [1,2] and $usersIds = [1,2,3]
I have nasted foreach loop like this:
foreach($projectsIds as $projecID){
foreach($userIds as $userID){
$sync_array[$projecID] = array('user_id' => $userID);
}
}
dd($sync_array);
now I get result like this:
array:2 [ 1 => array:1 [ "user_id" => 1 ]
2 => array:1 [ "user_id" => 1 ]
]
Is possible to get result something like this:
array:2 [ 1 => array:1 [ "user_id" => 1 ]
1 => array:1 [ "user_id" => 2 ]
1 => array:1 [ "user_id" => 3 ]
2 => array:1 [ "user_id" => 1 ]
2 => array:1 [ "user_id" => 2 ]
2 => array:1 [ "user_id" => 3 ]
]

You wish to make an array in PHP having two or more of instances of the same key, which is not possible at all!
Keys are meant to be treated as unique entities

Transform Laravel collection and group by key

I would like to transform a collection of object in laravel, but I can't figure it out how. I want to group the record by the type column, and set the grouped record under an array key value.
public function transformData()
{
$data = collect();
$matches = [ 'race', 'ethnicity'];
$attributes = Attribute::withTrashed()
->whereIn('type', $matches)
->get()
->groupBy('type');
$data->put(
$type, // to be the group key(like race)
[
'values' => $attributes->toArray(), // to be all the value with type race
]
);
dd(collect($data));
}
Here is what I'm getting:
Illuminate\Support\Collection^ {#2368
#items: array:1 [
"values" => array:2 [
"ethnicity" => array:2 [
0 => array:2 [
"id" => 1
"type" => "ethnicity"
]
1 => array:2 [
"id" => 2
"type" => "ethnicity"
]
]
"race" => array:2 [
0 => array:2 [
"id" => 6
"type" => "race"
]
1 => array:2 [
"id" => 7
"type" => "race"
]
]
]
]
#escapeWhenCastingToString: false
}
BUT I would like to return this instead:
Illuminate\Support\Collection^ {#2368
#items: array:1 [
"ethnicity" => array:2 [
"value" => array:2 [
0 => array:2 [
"id" => 1
"type" => "ethnicity"
]
1 => array:2 [
"id" => 2
"type" => "ethnicity"
]
]
]
"race" => array:2 [
"value" =>
0 => array:2 [
"id" => 6
"type" => "race"
]
1 => array:2 [
"id" => 7
"type" => "race"
]
]
]
#escapeWhenCastingToString: false
}

Store top categories from an API request into the database

I have an API request like this:
$postInformation =
(new postInformation)->handle(['field' => 'slug', 'value' => $this->slug]);
A dump of this response, besides other things, show some categories that are coming from this API request. And they are on this format where there is a 'categories' key with the top categories:
categories:
^ array:40 [
"id" => 2
...
"categories" => array:2 [
"data" => array:15 [
0 => array:3 [
"id" => 6
"name" => array:1 [
"en" => "General"
]
"on_request" => 0
]
1 => array:3 [
"id" => 14
"name" => array:1 [
"en" => "Tuts"
]
"on_request" => 0
]
2 => array:3 [
"id" => 3
"name" => array:1 [
"en" => "Laravel"
]
"on_request" => 0
]
...
]
...
]
I created a table 'post_top_categories' and a model PostTopCategory and I want to get the top categories from the API response above and store them into the 'post_top_categories' table. But I'm not understanding how to properly achieve this. Do you know how it can be achieved it? Thanks
foreach($yourArray['categories']['data'] as $topCategory)
{
$catId = $topCategory['id'];
$catname = $topCategory['name']['en'];
$catOnRequest = $topCategory['on_request'];
// Do what you want with those values now
}

Laravel 8: Sorting grouped array by a nested column - what should I put into sortBy closure?

I'm dealing with a specifically shaped array in Laravel where items are grouped by keys that represent names of categories.
In below example I have elements from categories 1, 5 and 76. Each element has a key called order which is a nullable integer that should indicate the order within this category.
array:3 [
"category_1" => array:4 [
1 => array:2 [
"option_name" => "Some name 1"
"option_items" => array:1 [
0 => array:5 [
"id" => 1
"price" => 200
"time" => 0
"order" => 999
]
]
]
2 => array:2 [
"option_name" => "Some name 2"
"option_items" => array:1 [
0 => array:5 [
"id" => 2
"price" => 780
"time" => 5
"order" => null
]
]
]
3 => array:2 [
"option_name" => "Some name 3"
"option_items" => array:1 [
0 => array:5 [
"id" => 3
"price" => 400
"time" => 4
"order" => null
]
]
]
4 => array:2 [
"option_name" => "Some name 4"
"option_items" => array:1 [
0 => array:5 [
"id" => 4
"price" => 300
"time" => 2
"order" => 434
]
]
]
]
"category_5" => array:2 [
6 => array:2 [
"option_name" => "Some name 5"
"option_items" => array:1 [
0 => array:5 [
"id" => 6
"price" => 890
"time" => 3
"order" => null
]
]
]
7 => array:2 [
"option_name" => "Some name 6"
"option_items" => array:1 [
0 => array:5 [
"id" => 7
"price" => 1290
"time" => 5
"order" => null
]
]
]
]
"category_76" => array:2 [
10 => array:2 [
"option_name" => "Some name 7"
"option_items" => array:1 [
0 => array:5 [
"id" => 10
"price" => 320
"time" => 4
"order" => 33
]
]
]
11 => array:2 [
"option_name" => "Some name 8"
"option_items" => array:2 [
0 => array:5 [
"id" => 11
"price" => 600
"time" => 0
"order" => 500
]
1 => array:5 [
"id" => 12
"price" => 2000
"time" => 9
"order" => 500
]
]
]
]
]
I simply want to sort this entire array per category by order key ascending (with nulls at the end), so for example the order of elements in category_1 would be:
Some name 4 (order of 434)
Some name 1 (order of 999)
Some name 2 (order is nor present / null)
Some name 3 (same as above)
What did you try?
Obviously I've tried converting this plain PHP array to collection and calling sortBy with a closure via:
$sorted = collect($array)->sortBy(function ($elementsInCategory, $key) {
dd($elementsInCategory); // $key is category_1
})->toArray();
but I simply don't know what to return from the callback to make it sort the way I've described.
BTW. I don't want to complicate too much but please notice that option_items sub-array may sometimes have more than one item (key 11 from category_76) but this does not matter - elements in this sub array will always have the same order value. This inner array should not be sorted - can be left as is.
You can use Laravel collection macro for that
$Collection::macro('sortByOrder', function (string $column = 'order', bool $descending = false) {
/* #var $this Collection */
return $this->sortBy(function ($order) use ($column) {
return strtotime(((object)$order)->$column);
}, SORT_REGULAR, $descending);
});
And you can use it like
$categories->sortByOrder('order',false);

how to remove a parent index array and change it to object in laravel

I have an array like below :
array:3 [
"2021-08-07" => array:3 [
"id" => "1"
"date" => "2021-08-07"
"numbers" => array:2 [
0 => 1
1 => 2
]
]
"2021-08-08" => array:3 [
"id" => "1"
"date" => "2021-08-08"
"numbers" => array:2 [
0 => 1
1 => 2
]
]
]
What I want to do is simply to remote the parent 2021-08-08 items because I have the date inside the array already . Now, what I have tried so far is :
$result = array_map(function ($el){
return $el[0];
},$test);
dd($result);
But it gives me error of undefined index[0] . what I want this array to look like is like below :
array:3 [
"id" => "1"
"date" => "2021-08-07"
"numbers" => array:2 [
0 => 1
1 => 2
],
"id" => "1"
"date" => "2021-08-08"
"numbers" => array:2 [
0 => 1
1 => 2
]
]
Won't just array_values() do?
array_values($test);
$test = array_values(yourArray);
$test = (object)$yourArray;

How to get value from unserialized data

I'm transforming my data into an array structure. Now I have the meta which already unserialized and I just need to take a specific value in meta.
Code
$item->meta;
$itm['attrs'] = #unserialize($item->meta);
$serial = #unserialize($item->meta);
$itm['product']['attrs'] = $itm['attrs'];
$itm['product']['serial'] = $serial['serial'];
Result
"product" => array:2 [
"attrs" => array:1 [
"serial" => array:1 [
0 => array:3 [
"id" => 848
"text" => "12345wf"
"trade_in" => 0
]
]
]
"serial" => array:1 [
0 => array:3 [
"id" => 848
"text" => "12345wf"
"trade_in" => 0
]
]
]
Expected Result
"product" => array:2 [
"attrs" => array:1 [
"serial" => array:1 [
0 => array:3 [
"id" => 848
"text" => "12345wf"
"trade_in" => 0
]
]
]
"serial" => "12345wf"
]
I'm not sure how to get the value and pass to the object.
