2 arrays match data into 1 array with PHP - php

Question

I have 2 array's, first array have for example ItemID of my item, second array have description about my item. I want to match data into 1 array.
It looks like:
[rgInventory] => Array
(
[1234567890] => Array
(
[id] => 1234567890
[classid] => 123456789
[instanceid] => 987654321
[amount] => 1
[pos] => 1
)
)
[rgDescriptions] => Array
(
[192837465_918273645] => Array
(
[appid] => 730
[name] => Something
)
)
Items in arrays don't have the same value like ID, but they are in the same order so:
Description for the first item in rgInventory is in the first array inside rgDescriptions.
What should I do to match for example id from rgInventory with name from rgDescriptions in the same array for example $backpack = array();?
Regards for you.

Try this:
<?php
$array1 = array('rgInventory' =>
array(
'1234567890' => array(
'id' => 1234567890,
'classid' => 123456789,
'instanceid' => 987654321,
'amount' => 1,
'pos' => 1
)
)
);
$array2 = array(
'rgDescriptions' => array(
'192837465_918273645' => array(
'appid' => 730, 'name' => 'Something')
)
);
Create new function to combine the two arrays into one array:
function array_sum_recursive($data1, $data2) {
if (!is_array($data1) && !is_array($data2)) {
return $data1 + $data2;
}
// deepest array gets precedence
if (!is_array($data2)) {
return $data1;
}
if (!is_array($data1)) {
return $data2;
}
//merge and remove duplicates
$keys = array_unique(array_merge(array_keys($data1), array_keys($data2)));
foreach ($keys as $key) {
if (isset($data1[$key]) && isset($data2[$key])) {
$result[$key] = array_sum_recursive($data1[$key], $data2[$key]);
} else if (isset($data1[$key])) {
$result[$key] = $data1[$key];
} else {
$result[$key] = $data2[$key];
}
}
if(empty($result)){
echo "no result";
die();
}else{
return $result;
}
}
Put the two array in one array $newarray:
$newonearray = array_sum_recursive($array1, $array2);
echo '<pre>';
print_r($newonearray);
?>
And you will get this:
Array
(
[rgInventory] => Array
(
[1234567890] => Array
(
[id] => 1234567890
[classid] => 123456789
[instanceid] => 987654321
[amount] => 1
[pos] => 1
)
)
[rgDescriptions] => Array
(
[192837465_918273645] => Array
(
[appid] => 730
[name] => Something
)
)
)
Hope this may help.

You can use function each to get each element of both arrays, then merge its with array_merge and save this new item to backup array.
Try something like this
<?php
$rgInventory = ['firstInv' => ['invId' => 1], 'secondInv' => ['invId' => 2]];
$rgDescriptions = ['firstDesc' => ['descId' => 1], 'secondDesc' => ['descId' => 2]];
if (count($rgInventory) && count($rgInventory) == count($rgDescriptions)) {
$backpack = [];
while($inventory = each($rgInventory)) {
$description = each($rgDescriptions);
$item = array_merge($inventory['value'], $description['value']);
$backpack[] = $item;
}
var_dump($backpack);
}
Output will be:
array(2) {
[0]=>
array(2) {
["invId"]=>
int(1)
["descId"]=>
int(1)
}
[1]=>
array(2) {
["invId"]=>
int(2)
["descId"]=>
int(2)
}
}
