PHP Question

Extract array index and merge the item in other array PHP

I have this array $all_designs_from_select_articles in PHP. Each index contains the objects Design:

array:7 [▼
0 => array:12 [▼
0 => Design {#297 ▶}
1 => Design {#298 ▶}
2 => Design {#299 ▶}
3 => Design {#300 ▶}
4 => Design {#301 ▶}
5 => Design {#302 ▶}
6 => Design {#303 ▶}
7 => Design {#304 ▶}
8 => Design {#305 ▶}
9 => Design {#306 ▶}
10 => Design {#307 ▶}
11 => Design {#308 ▶}
]
1 => array:15 [▼
0 => Design {#309 ▶}
1 => Design {#310 ▶}
2 => Design {#311 ▶}
3 => Design {#312 ▶}
4 => Design {#313 ▶}
5 => Design {#314 ▶}
6 => Design {#315 ▶}
7 => Design {#316 ▶}
8 => Design {#317 ▶}
9 => Design {#318 ▶}
10 => Design {#319 ▶}
11 => Design {#320 ▶}
12 => Design {#321 ▶}
13 => Design {#322 ▶}
14 => Design {#323 ▶}
]

]


But I want an array with all Design keys combined, like this:

array:26 [▼

0 => Design {#297 ▶}
1 => Design {#298 ▶}
2 => Design {#299 ▶}
3 => Design {#300 ▶}
4 => Design {#301 ▶}
5 => Design {#302 ▶}
6 => Design {#303 ▶}
7 => Design {#304 ▶}
8 => Design {#305 ▶}
9 => Design {#306 ▶}
10 => Design {#307 ▶}
11 => Design {#308 ▶}

12 => Design {#309 ▶}
13 => Design {#310 ▶}
14 => Design {#311 ▶}
15 => Design {#312 ▶}
16 => Design {#313 ▶}
17 => Design {#314 ▶}
18 => Design {#315 ▶}
19 => Design {#316 ▶}
20 => Design {#317 ▶}
21 => Design {#318 ▶}
22 => Design {#319 ▶}
23 => Design {#320 ▶}
24 => Design {#321 ▶}
25 => Design {#322 ▶}
26 => Design {#323 ▶}
...
etc
]


And this is my query to my API and get the first array values:

foreach ($search_articles as $article) {

$all_designs_from_select_articles[] = ApiDesign::getList([
'article_id' => $article,
'visibility' => 'ALL',
'order' => '-POPULARITY,NAME',
'lang' => 'multi,es',
]);
}


Is there a function in PHP to do this?
I´m using PHP7 and the framework laravel 5.2

Answer

You could merge the subarrays together after the fact with

$all_designs_from_select_articles = array_reduce(
    $all_designs_from_select_articles, "array_merge", []);

Or during the creation of the array:

foreach ($search_articles as $article) {
    $all_designs_from_select_articles = array_merge(
        $all_designs_from_select_articles,
        ApiDesign::getList(...));
}

I think I'd prefer the latter approach, but it's a marginal preference.
