How to merge inner array with same key value - php

Please help to solve this issue
i want to change this
[UI Testing] => Array
(
[0] => Array
(
[0] => 0
[1] => 70
)
[1] => Array
(
[0] => 40
[1] => 0
)
)
TO
[UI Testing] => Array
(
[0] => Array
(
[0] => 40
[1] => 70
)
)
Thanks.

Example
$myArray = array();
$myArray[] = array(0,70);
$myArray[] = array(40,0);
$sumArray = array();
foreach ($myArray as $k=>$subArray) {
foreach ($subArray as $id=>$value) {
array_key_exists( $id, $sumArray ) ? $sumArray[$id] += $value : $sumArray[$id] = $value;
}
}
print_r($sumArray);
Output:
Array
(
[0] => 40
[1] => 70
)

Array can be filtered to remove 0 valued indexes and array_reduce to merge array. An example below:
$arr = array('UI Testing' => array( array(0, 70), array(40, 0),) );
$new_arr['UI Testing'] = array_reduce($arr['UI Testing'], function($old, $new) {
return array_filter($new, function( $v ){ return $v > 0 ? $v : null; }) + $old;
}, []);
print '<pre>';
print_r($new_arr);
print '</pre>';
Output
Array
(
[UI Testing] => Array
(
[0] => 40
[1] => 70
)
)

Sum values in an multi-dimensional array

I want to sum the values of the following array
I would like to group the same items by cumulating them, the output format would also be an array
Array
(
[0] => Array
(
[0] => Array
(
[0] => R421_FD03
[1] => 1
)
[1] => Array
(
[0] => R421_FD03
[1] => 1
)
)
[1] => Array
(
[0] => Array
(
[0] => R421_FD03
[1] => 1
)
[1] => Array
(
[0] => R421_FD02
[1] => 1
)
)
)
I tested this code but the result is not the one I'm waiting for:
$sumArray = array();
array_walk_recursive($data, function($item, $key) use (&$sumArray){
$sumArray[$key] = isset($sumArray[$key]) ? $item + $sumArray[$key] : $item;
});
The result I'm waiting for is this one
Array
(
[0] => Array
(
[0] => R421_FD03
[1] => 3
)
[1] => Array
(
[0] => R421_FD02
[1] => 1
)
)
)
You can apply simple foreach() with array_values()
$final_array = [];
foreach($array as $arr){
foreach($arr as $ar){
$final_array[$ar[0]][0] = $ar[0];
$final_array[$ar[0]][1] = (isset($final_array[$ar[0]][1])) ? $final_array[$ar[0]][1] + $ar[1] : $ar[1];
}
}
$final_array = array_values($final_array);
print_r($final_array);
Output:-https://3v4l.org/lABWG
You can use array_merge with splat operator and then iterate through the array
$merged = array_merge(...$arr);//splat operator
$r = [];
array_walk($merged, function($v,$k) use(&$r){
array_key_exists($v['0'], $r) ? ($r[$v[0]] += $v['1']) : ($r[$v[0]] = $v[1]);
});
print_r($r);
Result :-
Array
(
[R421_FD03] => 3
[R421_FD02] => 1
)

Change value inside an array

I'd like to change the values of an array.
Currently my array looks like this:
Array
(
[0] => Array
(
[0] => 12-Multi_select-customfield-retina-ready+Yes
[1] => 12-Multi_select-customfield-retina-ready+N/A
[2] => 12-Multi_select-customfield-retina-ready+No
)
)
I want to remove everything before the + symbol, so in the end the new array will looke like this
Array
(
[0] => Array
(
[0] => Yes
[1] => N/A
[2] => No
)
)
This is my code:
$new_array = array();
foreach( $array as $key => $value ) {
$split = explode("+", $value[0]);
$new_array[] = $split[1];
}
Hoping that it would worked, but when I check the new array, it only shows one value.
Array
(
[0] => Yes
)
Any help in putting me in the right direction is much appreciated.
Please, check it:
<?php
$array[0][0] = '12-Multi_select-customfield-retina-ready+Yes';
$array[0][1] = '12-Multi_select-customfield-retina-ready+N/A';
$array[0][2] = '112-Multi_select-customfield-retina-ready+No';
echo '<pre>';
print_r($array);
$new_array = array();
foreach( $array[0] as $key => $value ) {
$split = explode("+", $value);
$new_array[] = $split[1];
}
print_r($new_array);
echo '</pre>';
Try This this work even if you have multiple key in the original array $original_array[0], $original_array[1] ... :
$original_array[0] = [
0 => '12-Multi_select-customfield-retina-ready+Yes',
1 => '12-Multi_select-customfield-retina-ready+N/A',
2 => '12-Multi_select-customfield-retina-ready+No'
];
print_r($original_array);
$new_array = [];
foreach ($original_array as $key => $value) {
foreach ($value as $index => $val) {
$split = explode("+", $val);
$new_array[$key][] = $split[1];
}
}
print_r($new_array);
Example :
Original array
Array
(
[0] => Array
(
[0] => 12-Multi_select-customfield-retina-ready+Yes
[1] => 12-Multi_select-customfield-retina-ready+N/A
[2] => 12-Multi_select-customfield-retina-ready+No
),
[1] => Array
(
[0] => 12-Multi_select-customfield-retina-ready+Yes
[1] => 12-Multi_select-customfield-retina-ready+N/A
[2] => 12-Multi_select-customfield-retina-ready+No
)
)
New Array
Array
(
[0] => Array
(
[0] => Yes
[1] => N/A
[2] => No
),
[1] => Array
(
[0] => Yes
[1] => N/A
[2] => No
)
)

Remove arrays that have a matching value from another array

$arr = Array
(
[0] => Array
(
[PropertyID] => 11
)
[1] => Array
(
[PropertyID] => 22
)
[2] => Array
(
[PropertyID] => 33
)
[3] => Array
(
[PropertyID] => 44
)
)
$excludeIDs = Array(22, 11, 44);
Desired outcome:
Array ( [0] => Array ( [PropertyID] => 33 ) )
I want to exclude the arrays that contain a matching PropertyID inside $excludeIDS
How may I do this?
Use unset() through the array:
foreach($arr as $key => $value){
if(in_array($value['PropertyID'], $excludeIDs)){
unset($arr[$key]);
}
}
$arr = array_values($arr);
print_r($arr);
Output:
Array
(
[0] => Array
(
[PropertyID] => 33
)
)
Try this :
<?php
$excludeIDs = array(22, 11, 44);
$counter = 0;
foreach ($arr as $key => $value) {
if (!in_array($value['PropertyID'], $excludeIDs)) {
$result_array[$counter] = $value;
$counter++;
}
}
echo '<pre>';
print_r($result_array);
echo '</pre>';
?>

Assigning an array as a value of another array

I have three arrays i need to create an array which can be multidimensional.
1st array
Array
(
[0] => Test_One
[1] => Test_two
)
2nd array
Array
(
[0] => www.link.com
[1] => www.link2.com
)
3rd array
Array
(
[0] => Song1
[1] => song2
)
What i want
Array
(
[www.link.com] => Array
(
[0] => Test_one
[1] => Song1
)
[www.link2.com] => Array
(
[0] => Test_two
[1] => Song2
)
)
Assuming that you have same number of elements in all three arrays:
<?php
$arr1 = Array
(
0 => "Test_One",
1 => "Test_two"
);
$arr2 = Array
(
0 => "www.link.com",
1 => "www.link2.com"
);
$arr3 = Array
(
0 => "Song1",
1 => "Song2"
);
$final = []; //for versions below PHP 5.4 use $final = array();
foreach($arr2 as $key=>$value) {
$final[$value] = [$arr1[$key],$arr3[$key]];
}
print_r($final);
will output:
Array
(
[www.link.com] => Array
(
[0] => Test_One
[1] => Song1
)
[www.link2.com] => Array
(
[0] => Test_two
[1] => Song2
)
)
Update: Simplified foreach loop. From Comments #uchiha
Assuming that you havn't same number of elements in all three arrays:

}
if(array_key_exists($key,$arr3)) {
$final[$value][] = $arr3[$key];
}
}
print_r($final);
Output:

(
[0] => Test_One
[1] => Song1
)
[www.link2.com] => Array
(
[0] => Test_two
)
)
Hope this help :)
<?php
$array1 = Array
(
'Test_One',
'Test_two'
);
$array2 = Array
(
'www.link.com',
'www.link2.com'
);
$array3 = Array
(
'Song1',
'song2'
);
$array4 = array();
$i = 0;
foreach ($array2 as $a2){
$array4[$a2][] = $array1[$i];
$array4[$a2][] = $array3[$i];
$i++;
}
echo "<pre>";
print_r($array4);

How to sum array values based on keys?

The first array
Array
(
[0] => Array
(
[1] => 2
)
[1] => Array
(
[1] => 2
)
[2] => Array
(
[2] => 1
)
[3] => Array
(
[3] => 1
)
)
I want output like
Array
(
[0] => Array
(
[1] => 4
)
[1] => Array
(
[2] => 1
)
[2] => Array
(
[3] => 1
)
)
How can i do this?
Seems like a good case for array_reduce():
$res = array_chunk(array_reduce($arr, function(&$current, $item) {
foreach ($item as $key => $value) {
if (!isset($current[$key])) {
$current[$key] = 0;
}
$current[$key] += $value;
}
return $current;
}, []), 1, true);
For the final result I'm using array_chunk(); it takes an array and creates single element sub arrays of each element.
$result = array();
foreach ($input as $subarray) {
foreach ($subarray as $key => $value) {
if (isset($result[$key])) {
$result[$key][$key] += $value;
} else {
$result[$key] = array($key => $value);
}
}
}
$result = array_values($result); // Convert from associative array to indexed array
