Adding to new array if key in multiarray check - php

Question

I have multidimensional array $items and I need to search it and then create new array(s).
This array is generated at the end of check-up in e-shop I'm trying to build, so array can be of random length. I need to create to create new array for every new supplier_id so I can send data to each and every one of them apart.
I already have code for making order but now it just takes all data at once. So in this particular example I'm expecting 3 multidimensional arrays that I can run trough my create_order code.
I know there are many threads talking about multidimensional arrays but none that I can understand enough to apply it in my case. Thanks very much for help.
Here is what $items may look like
array (4)
id => 36
count => 1
product => Nette\Database\Table\ActiveRow #7c60
table private => Nette\Database\Table\Selection #739c
data private => array (3)
product_id => 36
price => 219.0
supplier_id => 3
dataRefreshed private => FALSE
names => array (1)
en => "Product 1" (9)
array (4)
id => 180
count => 1
product => Nette\Database\Table\ActiveRow #938b
table private => Nette\Database\Table\Selection #a5f0
data private => array (3)
product_id => 180
price => 375.0
supplier_id => 4
dataRefreshed private => FALSE
names => array (1)
en => "Product 2" (9)
array (4)
id => 309
count => 1
product => Nette\Database\Table\ActiveRow #4c67
table private => Nette\Database\Table\Selection #8f56
data private => array (3)
product_id => 309
price => 40.0
supplier_id => 5
dataRefreshed private => FALSE
names => array (1)
en => "Product 3" (9)

So after few hours of digging I was amazed how easily it can by done
// searching for all unique supplier_id
$uniqueID = array();
foreach ($items as $item) {
if (!in_array($item['product']['supplier_id'], $uniqueID)) {
array_push($uniqueID, $item['id'] = $item['product']['supplier_id']);
}
}
// visual check of all unique *supplier_id*
dump($uniqueID);
// creation of array where I'm going to insert all necessary data
foreach ($uniqueID as $array) {
$defined_array = [];
// visual check for debugging purposes
dump("start");
// creating multiarray for every unique *supplier_id* and inserting data
foreach ($items as $item) {
if($item['product']['supplier_id'] == $array) {
$defined_array[] = $item;
}
}
// final check of all arrays + debug check for end --
// at the end this block is replaced by *create_order* code
foreach ($defined_array as $array) {
dump($array);
}
dump("end");
}
At the end I hope it will help to someone at least.
