how to get array with unique values in laravel/php - php

Question

I need to merge arrays into 1 array but what I need is to remove before the main data they b oth have in common (duplicated values i mean), I need only unique values when merged.
array formed from foreach.
public $arrayfields= [];
public $itemMap = [];
public function getRowMapping(array $row,$uniqueField,$moduleName)
{
$arrayData = [];
foreach ($this->columnMapping as $key => $value) {
$row = $this->moduleType($key,$value,$row,$moduleName);
}
$unique = $row[$uniqueField];
if(!isset($this->itemMap[$unique])){
$this->itemMap[$unique] = $row;
$this->itemMap[$unique][$unique]['items'] = [];
}
$this->itemMap[$unique]['items'][] = $row['items'];
return $row;
}
i changed little bit to my input
How can i do that?
so now the input will be like this
Array
(
[bill_type] => 1
[bill_number] => BIL-003
[order_number] => ON-003
[items] => Array
(
[track_inventory] => 0
[sku1] => sku1
[name] => Kidswear1
)
)
Array
(
[bill_type] => 1
[bill_number] => BIL-003
[order_number] => ON-003
[items] => Array
(
[track_inventory] => 0
[sku1] => sku2
[name] => Pant
)
)
Array
(
[bill_type] => 1
[bill_number] => BIL-002
[order_number] => ON-002
[items] => Array
(
[track_inventory] => 0
[sku1] => sku3
[name] => Pants
)
)
The final output I'm looking for is
Array
(
[BIL-003] => Array
(
[bill_type] => 1
[order_number] => ON-003
[items] => Array
(
[0] => Array(
[track_inventory] => 0
[sku1] => sku1
[name] => Kidswear1
)
[1] => Array
(
[track_inventory] => 0
[sku1] => sku2
[name] => Pant
)
)
[BIL-002] => Array
(
[bill_type] => 1
[order_number] => ON-002
[items] => Array
(
[0] => Array(
[track_inventory] => 0
[sku1] => sku3
[name] => pants
)
)
)~~~

Answer 1

I think there is no standard library function to accomplish this.
So here is the function that accomplishes this:
function merge($array1, $array2)
{
$arraymerged = [];
if (is_array($array1) && is_array($array2)) {
//collect the keys of two arrays
$keys = [];
foreach ($array1 as $key => $value) {
$keys[$key] = true;
}
foreach ($array2 as $key => $value) {
$keys[$key] = true;
}
//merge key values for each key
foreach ($keys as $key => $value) {
if (isset($array1[$key]) && isset($array2[$key])) {
if ($array1[$key] == $array2[$key]) {
$arraymerged[$key] = $array1[$key];
} else {
$arraymerged[$key] = [$array1[$key], $array2[$key]];
}
} else if (isset($array1[$key]))
$arraymerged[$key] = $array1[$key];
else
$arraymerged[$key] = $array2[$key];
}
return $arraymerged;
}
}

Answer 2

Here is my suggestion,
if the input is array, check my answer on this post Convert an associative array into an associative array which has a key with another associative array as its value in php
otherwise check below code.
bill_number as unique key and run foreach and append items array elements.
let me give you an example
$arr1 = [
"bill_type" => 1,
"bill_number" => 'BIL-003',
"items"=>[
0 => [
"name"=>"test"
]
]
];
$arr2 = [
"bill_type" => 1,
"bill_number" => 'BIL-003',
"items"=>[
0 => [
"name"=>"test_2"
]
]
];
$formattedArr = [];
//merge these arrays
$combinedArr = [];
$combinedArr[] = $arr1;
$combinedArr[] = $arr2;
foreach($combinedArr as $key=>$value){
$formattedArr[$value['bill_number']]["bill_type"] = $value["bill_type"];
$formattedArr[$value['bill_number']]["items"][] = $value["items"];
}
print_r($formattedArr);
I haven't tested this code, but i think this will be ans to your question.

<?php
$a1 = array(
"bill_type" => "1",
"bill_number" => "BIL-003",
"order_number" => "ON-003",
"items" => array(
"track_inventory" => "0",
"sku1" => "sku1",
"name" => "Kidswear1"
)
);
$a2 = array(
"bill_type" => "1",
"bill_number" => "BIL-003",
"order_number" => "ON-003",
"items" => array(
"track_inventory" => "0",
"sku1" => "sku2",
"name" => "Pant"
)
);
$result = function ($a1, $a2) {
$b1 = $a1['items'];
$b2 = $a2['items'];
$c1 = $a1;
$c2 = $a2;
unset($c1['items']);
unset($c2['items']);
if (count(array_diff($c1, $c2)) == 0) {
if (count(array_diff($b1, $b2)) != 0) {
$c1['items'] = [$b1, $b2];
} else {
$c1['items'] = $b1;
}
return $c1;
}else{
//you should complete this part by yourself, if first parts are not equal.
}
return $c1;
};
$r = $result($a1, $a2);
var_dump($r);
result:
(array) [4 elements]
bill_type: (string) "1"
bill_number: (string) "BIL-003"
order_number: (string) "ON-003"
items:
(array) [2 elements]
0:
(array) [3 elements]
track_inventory: (string) "0"
sku1: (string) "sku1"
name: (string) "Kidswear1"
1:
(array) [3 elements]
track_inventory: (string) "0"
sku1: (string) "sku2"
name: (string) "Pant"
