How do I achieve this help
You can flat the multi dimension array first, then sort it. Demo
$flat_array = [];
foreach($multi_dimension_array as $k => $array){
foreach($array as $value){
$flat_array[] = array(
$k => $value
);
}
}
usort($flat_array,function($a,$b){return current($a)["position"] - current($b)["position"];});
print_r($flat_array);
Though this code works, But I suggest restruct the data source for better data format. Which can make it a easy work
I have this array of userids. I want to combine the child userid arrays into one array within the parent arrays.
[0] => Array
(
[0] => Array
(
[userid] => 1610
)
[1] => Array
(
[userid] => 1614
)
[2] => Array
(
[userid] => 1616
)
)
[1] => Array
(
[0] => Array
(
[userid] => 1610
)
[1] => Array
(
[userid] => 1614
)
[2] => Array
(
[userid] => 1616
)
[3] => Array
(
[userid] => 1618
)
)
My desired result would look like...
[0] => Array
(
[userids] => Array
(
[0] => 1610
[1] => 1614
[2] => 1616
)
)
[1] => Array
(
[userids] => Array
(
[0] => 1610
[1] => 1614
[2] => 1616
[3] => 1618
)
)
Loop the array and use array_column to flatten the subarrays.
foreach($arr as $sub){
$res[][key($sub[0]) . "s"] = array_column($sub, 'userid');
}
var_dump($res);

I have an array
Array
(
[0] => Array
(
[0] => 96
[1] => ML based
[7] => Open
)
)
Array
(
[0] => Array
(
[0] => 97
[1] => Application
[7] => Open
)
)
Array
(
[0] => Array
(
[0] => 98
)
)
Array
(
[0] => Array
(
[0] => 99
)
)
I want to remove
Array
(
[0] => Array
(
[0] => 98
)
)
Array
(
[0] => Array
(
[0] => 99
)
)
from this array
I tried:
$data = array_map('array_filter', $rowData);
unset($data[0][0]);
Expected output:
Array
(
[0] => Array
(
[0] => 96
[1] => ML based )
[7] => Open
)
)
Array
(
[0] => Array
(
[0] => 97
[1] => Application
[7] => Open
)
)
any help would be Appreciated .
array_filter() will work. Try -
array_filter($array, function ($a) {
return count($a[0]) == 3; // return array with 3 elements only
});
Working code
I have an array $result as such:
[0] => Array (
[0] => Array (
[itemid] => 1
[name] => A
)
[1] => Array (
[itemid] => 2
[name] => B
)
)
[1] => Array (
[0] => Array (
[itemid] => 3
[name] => C
)
[1] => Array (
[itemid] => 2
[name] => B
)
)
and an array $items as such:
[0] => Array (
[itemid] => 2
[name] => B
)
[1] => Array (
[itemid] => 4
[name] => D
)
How do I remove all items from the $result array, that occur in the $items array? In this case, the $result would become:
[0] => Array (
[0] => Array (
[itemid] => 1
[name] => A
)
)
[1] => Array (
[0] => Array (
[itemid] => 3
[name] => C
)
)
Since the question is mostly code, here's some extra characters to make StackOverflow accept the question.
I think this is what you want. (Not tested yet)
<?php
foreach ($result as $key => $array) {
$result[$key] = array_diff($array, $items);
}
print_r($result);

From this i want to get an array
$output= [SAMSUNG => 9341, XIAOMI => 4807]
Here each item contains sum of the items in nested array.
Currently my solution conatins more than 2 for each loops but is there any way to optimize this??
You can use array_sum, array_map and array_column functions to get the result
array_sum(array_map('array_sum', array_column($a, 'SAMSUNG')))
With single array_reduce function:
// $arr is your initial array
$result = array_reduce($arr, function($r, $v){
if (isset($v['SAMSUNG'])) $r['SAMSUNG'] += array_sum($v['SAMSUNG']);
if (isset($v['XIAOMI'])) $r['XIAOMI'] += array_sum($v['XIAOMI']);
return $r;
}, ['SAMSUNG' => 0, 'XIAOMI' => 0]);
$sumArray = array();
foreach ($YourArray as $k=>$subArray) {
foreach ($subArray as $id=>$value) {
$sumArray[$id]+=$value;
}
}
print_r($sumArray);
