Find Unique Value from a array - php

Question

I have a Multidimensional array, I need to find if array have same value of 'brand' attribute then return its id.
I tried via some array functions but it didn't work.
What I Tried:
1)
$backwards = array_reverse($attribute);
echo '<pre>';
$last_item = NULL;
$i = 0;
foreach ($backwards as $current_item) {
if ($last_item === $current_item[$i]['value']) {
echo '<pre>'; print_r($current_item[$i]['value']);
}
$last_item = $current_item[$i]['value'];
echo '<pre>'; print_r($last_item);
$i++;
}
2)
$j = 1;
$i = 0;
foreach ($attributeValues as $attributeData) {
foreach ($attribute as $value) {
if($value[$i]['value'] == $value[$j]['value']) {
echo '<pre>'; print_r($value); die();
}
$j++;
}
}
All my solution's not worked, please help.

[price] => 15000.0000

[1] => Array
(
[name] => model

[0] => Array
(
[name] => brand
[value] => 89
[id] => 518
[price] => 100.0000
)
[1] => Array
(
[name] => model
[value] => 12
[id] => 518
[price] => 100
)
)
If [name]=>brand and [name]=>model value's of first array is same as second array's value then return [id].

Answer 1

You need two for loop.
$result =[];
foreach ($arr as $key => $value) {
foreach($value as $v){
$result[$v['name']][] = $v['id'];
}
}
$result = array_map("array_unique", $result); // to make it unique
print_r($result);
// if you want to check ids for brand
//print_r($result['brand']);
Output:
Array
(
[brand] => Array
(
[0] => 5251
[1] => 5250
[3] => 518
)
[model] => Array
(
[0] => 5251
[1] => 518
)
)
Demo.
EDIT
Then you can group it by name and value of it
$result =[];
foreach ($arr as $key => $value) {
foreach($value as $v){
$result[$v['name']."|".$v['value']][] = $v['id'];
}
}
$result = array_map("array_unique", $result);
print_r($result);die;
Demo.

Answer 2

you can use foreach and iterate through the array
$res = [];
foreach($arr as $k => $v){
if($v[0]['name'] == $v[1]['name'])
$res[$v[0]['name']] = $v[0]['id'];
}
If you want to match the index value try this
foreach($arr as $k => $v){
if($v[0]['value'] == $v[1]['value'])
$res[] = $v[0]['id'];
}
