I am having some difficulty manipulating the below array. I have tried various things and I feel like there should be a simple way to achieve this, but I cannot seem to figure it out. Any tips or help greatly appreciated, thanks!
Array
(
[0] => Array
(
[0] => Array
(
[Color] => Blue
)
[1] => Array
(
[Size] => S
)
)
[1] => Array
(
[0] => Array
(
[Color] => Blue
)
[1] => Array
(
[Size] => M
)
)
)
My desired outcome is:
Array
(
[0] => Array
(
[Color] => Blue
[Size] => S
)
[1] => Array
(
[Color] => Blue
[Size] => M
)
)
This works:
$items = array(
array(
array("Color" => "Blue"),
array("Size" => "S")
),
array(
array("Color" => "Blue"),
array("Size" => "M")
)
);
$new_items = array();
foreach ($items as $item) {
$collect = array();
foreach ($item as $values) {
foreach ($values as $key => $value) {
$collect[$key] = $value;
}
}
$new_items[] = $collect;
}
var_dump($new_items);
Your array is 3 deep, so you need at least 3 nested loops.
Output:
array(2) {
[0]=>
array(2) {
["Color"]=>
string(4) "Blue"
["Size"]=>
string(1) "S"
}
[1]=>
array(2) {
["Color"]=>
string(4) "Blue"
["Size"]=>
string(1) "M"
}
}
2 loops are enough with array_merge
$a = array(
array(
array(
'Color' => 'Blue'
),
array(
'Size' => 'S'
),
),
array(
array(
'Color' => 'Blue'
),
array(
'Size' => 'M'
),
),
);
$c = array();
foreach($a as $b)
{
$ca = array();
if(is_array($b))
{
foreach($b as $array)
{
$ca = array_merge($ca, $array);
}
$c[] = $ca;
}
}
echo '<pre>'.print_r($c,true);
You can use array_map for this:
<?php
function combine($elementArray)
{
return array($elementArray[0]["Color"], $elementArray[1]['Size']);
}
$originalArray = array(
0 => array(
0 => array("Color" => "Blue"),
1 => array("Size" => "S")
),
1 => array(
0 => array( "Color" => "Blue"),
1 => array("Size" => "M")
)
);
$combinedArray = array_map("combine", $originalArray);
echo "<pre>";
print_r($combinedArray);
?>
Also you can use anonymous functions and do it like a pro ;)
$combinedArray = array_map(
function($element){
return array(
"Color" => $element[0]["Color"],
"Size" => $element[1]['Size']
);
},$originalArray);
Or you can even use array_reduce example:
$reducedArray = array_reduce($originalArray, function($result, $item){
$result[] = array(
'Color' => $item[0]['Color'],
'Size' => $item[1]['Size']
);
return $result;
});
Hope this will help
$array =
array(
array(
array(
'color'=>'Blue'
),
array(
'size'=>'s'
)
),
array(
array(
'color'=>'Red'
),
array(
'size'=>'m'
)
)
);
$mA = array();
foreach($array as $k=>$a){
array_push($mA,array_merge($a[0],$a[1]));
}
var_dump($mA);

I am using php 7.1 and I have the following array:
<?php
$arr = array (
0 =>
array (
'Product' => 'Product1',
'Exact_Match_Keyword' => 'apples freshness',
),
1 =>
array (
'Product' => 'Product1',
'Exact_Match_Keyword' => 'apples',
),
2 =>
array (
'Product' => 'Product1',
'Exact_Match_Keyword' => 'oranges',
),
3 =>
array (
'Product' => 'Product2',
'Exact_Match_Keyword' => 'apples freshness',
),
4 =>
array (
'Product' => 'Product2',
'Exact_Match_Keyword' => 'apples',
),
);
$arr = array_merge_recursive($arr);
var_dump($arr);
/* WANTED DATA STRUCTURE
$arr = array (
0 =>
array (
'Product' => 'Product1',
'Exact_Match_Keyword' => array('apples freshness', 'apples', 'oranges'),
),
1 =>
array (
'Product' => 'Product2',
'Exact_Match_Keyword' => array('apples freshness', 'apples'),
),
);
*/
I tried to use array_merge_recursive however this does not give me my wanted data structure.
Any suggestions what I am doing wrong?
I appreciate your replies!
You can use array_reduce to handle simple logic like this for you. The example below will provide you with the expected format you've posted.
$example = array_values(
array_reduce(
$arr,
static function ($acc, $row) {
if (!isset($acc[$row['Product']])) {
$acc[$row['Product']] = [
'Product' => $row['Product'],
'Exact_Match_Keyword' => [$row['Exact_Match_Keyword']],
];
} else {
$acc[$row['Product']]['Exact_Match_Keyword'] = array_merge(
$acc[$row['Product']]['Exact_Match_Keyword'],
[$row['Exact_Match_Keyword']]
);
}
return $acc;
}
));
print_r($example);
It can be simplified further if the format you expect is flexible:
$example = array_reduce(
$arr,
static function ($acc, $row) {
if (!isset($acc[$row['Product']])) {
$acc[$row['Product']] = [$row['Exact_Match_Keyword']];
} else {
$acc[$row['Product']] = array_merge(
$acc[$row['Product']],
[$row['Exact_Match_Keyword']]
);
}
return $acc;
}
);
print_r($example);
//Output:
//[
// 'Product1'=> ['apples freshness', 'apples', 'oranges'],
// 'Product2'=> ['apples freshness', 'apples']
//]
I think this gets you what you want. Probably not the most graceful thing in the world but it's roughly the logic you'd want to follow.
$temp = [];
foreach ($arr as $v)
{
$pname = $v['Product'];
if (!isset($temp[$pname]))
{
$temp[$pname] = [];
}
$temp[$pname][] = $v['Exact_Match_Keyword'];
}
$out = [];
foreach ($temp as $k => $v)
{
$out[] = [
'Product' => $k,
'Exact_Match_Name' => $v
];
}
php > var_dump($out);
php shell code:1:
array(2) {
[0] =>
array(2) {
'Product' =>
string(8) "Product1"
'Exact_Match_Name' =>
array(3) {
[0] =>
string(16) "apples freshness"
[1] =>
string(6) "apples"
[2] =>
string(7) "oranges"
}
}
[1] =>
array(2) {
'Product' =>
string(8) "Product2"
'Exact_Match_Name' =>
array(2) {
[0] =>
string(16) "apples freshness"
[1] =>
string(6) "apples"
}
}
}
For future reference, if you would like to use the array_merge_recursive() approach on its own, the input data might have to be a little different from what I can tell.
After looking at the example in the documentation page for array_merge_recursive(), I wonder if the original input data needs to be structured a little differently. I think there needs to be matching inner array keys in order for the final array to have something to combine on for the various inner keys. In the example data below, I used the Products key to combine on for the first inner key.
I don't know if it's possible for your starting data to be structured differently for this process, but if the data could look like the following (based on the example on the documentation page for array_merge_recursive()):
<?php
$ar1 = array(
"Products" => array(
"Product1" => array(
"Exact_Match_Keyword" => array('apples freshness')
)
)
);
$ar2 = array(
"Products" => array(
"Product1" => array(
"Exact_Match_Keyword" => array('apples')
)
)
);
$ar3 = array(
"Products" => array(
"Product1" => array(
"Exact_Match_Keyword" => array('oranges')
)
)
);
$ar4 = array(
"Products" => array(
"Product2" => array(
"Exact_Match_Keyword" => array('apples freshness')
)
)
);
$ar5 = array(
"Products" => array(
"Product2" => array(
"Exact_Match_Keyword" => array('apples')
)
)
);
$result = array_merge_recursive($ar1, $ar2, $ar3, $ar4, $ar5);
print_r($result);
The output should then look like this:
Array
(
[Products] => Array
(
[Product1] => Array
(
[Exact_Match_Keyword] => Array
(
[0] => apples freshness
[1] => apples
[2] => oranges
)
)
[Product2] => Array
(
[Exact_Match_Keyword] => Array
(
[0] => apples freshness
[1] => apples
)
)
)
)
I have an array looks like this:
Array
(
[0] => Array
(
[name] => color
[value] => red
)
[1] => Array
(
[name] => shape
[value] => square
)
[2] => Array
(
[name] => price
[value] => $15
)
)
I want to have a result like this:
$myArr = array (
'color' => 'red',
'shape' => 'square',
'price' => '$15'
)
I have tried to loop but can not get it to work.
foreach($myArr as $id => $values){
foreach ($values as $key => $value) {
if($key == 'name') {
//add to array key
} else {
//add to that array key value
}
}
}
hope you guys can help me with solution.
You can use array_column and array_combine
$arr = array(
array("name" => 'color',"value" => 'red'),
array("name" => 'shape',"value" => 'square'),
array("name" => 'price',"value" => '$15')
);
$newArr = array_combine(array_column($arr,'name'),array_column($arr,'value'));
echo "<pre>";
print_r( $newArr );
echo "</pre>";
This will result to:
Array
(
[color] => red
[shape] => square
[price] => $15
)
Doc: array_column, array_combine
$a = [
0 => [
"name" => "color",
"value" => "red",
],
1 => [
"name" => "shape",
"value" => "square",
],
2 => [
"name" => "price",
"value" => "$15",
]
];
$b = [];
foreach($a as $v)
{
$b[$v["name"]] = $v["value"];
}
var_dump($b);
result
array(3) {
["color"]=>
string(3) "red"
["shape"]=>
string(6) "square"
["price"]=>
string(3) "$15"
}
$arr = array
(
0 => array
(
'name' => 'color',
'value' => 'red'
),
1 => array
(
'name' => 'shape',
'value' => 'square'
),
2 => array
(
'name' => 'price',
'value' => '$15'
)
);
$final_array =[];
foreach($arr as $key=> $val){
$final_array[$val['name']] = $val['value'];
}
echo "<pre>"; print_r($final_array);
I have data below :
Array(
[A] => Array
(
[AA] => 10
)
[B] => Array
(
[BA] => 5
[BB] => 1
[BC] => -2
)
[C] => Array
(
[CA] => 3
[CB] => 0
)
)
I want to sum the value of second element my array (BA,BB,BC, etc) like this :
Array(
[A] => 10
[B] => 4
[C] => 3
)
I've tried to do with foreach (I'm using php as my platform) but the result is wrong, can someone give me explanation and the logic to solve this? thanks
You can loop thru your array and use array_sum
$arr = array(
"A" => array
(
"AA" => 10,
),
"B" => array
(
"BA" => 5,
"BB" => 1,
"BC" => -2
),
"C" => array
(
"CA" => 3,
"CB" => 0
)
);
$result = array();
foreach( $arr as $key => $val ){
$result[$key] = array_sum ( $val );
}
echo "<pre>";
print_r( $result );
echo "</pre>";
This will result to:
Array
(
[A] => 10
[B] => 4
[C] => 3
)
Doc: http://php.net/manual/en/function.array-sum.php
This should work for arrays like the one of your example:
$arr = array(
"A" => array
(
"AA" => 10,
),
"B" => array
(
"BA" => 5,
"BB" => 1,
"BC" => -2
),
"C" => array
(
"CA" => 3,
"CB" => 0
)
);
$res = array();
foreach($arr as $key => $value) {
foreach($value as $number) {
(!isset($res[$key])) ?
$res[$key] = $number :
$res[$key] += $number;
}
}
echo "<pre>";
print_r( $res );
echo "</pre>";
This is working without using an inbuilt function.
if you want sum column
<?php
$array = array
(
"A"=>array
(
"AA" => 10,
),
"B"=>array
(
"BA" => 5,
"BB" => 1,
"BC" => -2
),
"C"=>array
(
"CA" => 3,
"CB" => 0
)
);
foreach ($array as $key=>$value)
{
$mehrdad[]=$key;
}
foreach ($mehrdad as $key1=>$value1)
{
$arrays=$array[$value1];
foreach ($arrays as $key2=>$value2)
{
$mehrdadi[]=$key2;
}
}
$mehrdadend=array_unique($mehrdadi);
$mehrdadis = array();
foreach ($mehrdadend as $key3=>$value3)
{
$sum=array_sum(array_column($array, $value3));
$mehrdadis[$value3] = $sum;
}
print_r($mehrdadis);
?>
Result
Array
(
[AA] => 10
[BA] => 5
[BB] => 1
[BC] => -2
[CA] => 3
[CB] => 0
)
This question may sound silly, but I didn't find a good approach.
I have to multidimensional arrays like this:-
array
(
[0] => Array
(
[field1] => A
[field2] => 100
[field3] => 20
)
[1] => Array
(
[field1] => B
[field2] => 100
[field3] => 30
)
[2] => Array
(
[field1] => C
[field2] => 100
[field3] => 30
)
)
array
(
[0] => Array
(
[field1b] => A
[field2b] => 500
[field3b] => 0
)
[1] => Array
(
[field1b] => B
[field2b] => 300
[field3b] => 10
)
)
I want to merge both arrays using field1 as Key, and having in mind that arrays aren't same size.
The result array should be:
array
(
[0] => Array
(
[field1] => A
[field2] => 100
[field3] => 20
[field2b] => 500
[field3b] => 0
)
[1] => Array
(
[field1] => B
[field2] => 100
[field3] => 30
[field2b] => 300
[field3b] => 10
)
[2] => Array
(
[field1] => C
[field2] => 100
[field3] => 30
)
)
Thanks in advance!
Try this,

Very simple:- apply foreach and do it like below:-
<?php
$final_array = array();
foreach ($arr1 as $key=>$val){
if(isset($arr2[$key])){
$final_array[$key] = array_merge($val,$arr2[$key]);
unset($final_array[$key]['field1b']);
}else{
$final_array[$key] = $val;
}
}
echo "<pre/>";print_r($final_array);
Output:- https://eval.in/661803
If your both array have different number of elements then :-
<?php
$count1 = count ($arr1);
$count2 = count ($arr2);
$final_array = array();
if ($count1 >$count2){
foreach ($arr1 as $key=>$val){
if(isset($arr2[$key])){
$final_array[$key] = array_merge($val,$arr2[$key]);
unset($final_array[$key]['field1b']);
}else{
$final_array[$key] = $val;
}
}
echo "<pre/>";print_r($final_array);
}else if ($count2 >$count1){
foreach ($arr2 as $key=>$val){
if(isset($arr1[$key])){
$final_array[$key] = array_merge($val,$arr1[$key]);
unset($final_array[$key]['field1b']);
}else{
$final_array[$key] = $val;

You can try it.
What about this instead defining hard-coded keys condition? all you need is to provide the key which should not be included in combined array..
Demo
<?php
$A = array(
array(
'field1' => 'A',
'field2' => '100',
'field3' => '20',
),
array(
'field1' => 'B',
'field2' => 100,
'field3' => 30,
),
array(
'field1' => 'C',
'field2' => 100,
'field3' => 30,
)
);
$B = array(
array(
'field1b' => 'A',
'field2b' => 500,
'field3b' => 0
),
array(
'field1b' => 'B',
'field2b' => 300,
'field3b' => 10
)
);
$combined = array();
foreach($A as $key => $arr) {
$tempKey = reset($arr);
$second_arr = $B[ $key ];
$tempKey2 = reset($B[ $key ]);
if( $tempKey == $tempKey2 ) {
$combined[] = $arr + $second_arr;
unset( $combined[ $key ]['field1b'] );
}
else {
$combined[] = $arr;
}
}
echo '<pre>';
print_r($combined);

I have an array $array1 with different amount of key and value pairs:
Array
(
[0] => Array
(
[ID] => 39
[title] => Apple
)
[1] => Array
(
[ID] => 40
[title] => Orange
)
)
and another array $array2:
Array
(
[0] => 273
[1] => 386
)
And I want to get this:
Array
(
[0] => Array
(
[ID] => 39
[title] => Apple
[pages] => 273
)
[1] => Array
(
[ID] => 40
[title] => Orange
[pages] => 386
)
)
The number of items in each array is the same and the correspond, so, we don't need to check this, so, how to merge it like that?
use array_replace_recursive if you want merge with integer keys, or array_merge_recursive if you want merge only string keys
<?php
$a1 = array(
0 => array
(
"ID" => 39,
"title" => "Apple"
),
1 => array(
"ID" => 40,
"title" => "Orange"
)
);
$a2 = array(
0 => array
(
"pages" => 273,
"year" => 1981
),
1 => array(
"pages" => 386,
"year" => 1979
)
);
$a3 = array_replace_recursive($a1, $a2);
var_dump($a3);
Result:
array(2) {
[0] =>
array(4) {
'ID' =>
int(39)
'title' =>
string(5) "Apple"
'pages' =>
int(273)
'year' =>
int(1981)
}
[1] =>
array(4) {
'ID' =>
int(40)
'title' =>
string(6) "Orange"
'pages' =>
int(386)
'year' =>
int(1979)
}
}
Answer for updated question:
<?php
$a1 = array(
0 => array
(
"ID" => 39,
"title" => "Apple"
),
1 => array(
"ID" => 40,
"title" => "Orange"
)
);
$a2 = array(
0 => 31,
1 => 324
);
$defaultValue = 0;
foreach ($a1 as $key => $value) {
$a1[$key]['pages'] = isset($a2[$key]) ? $a2[$key] : $defaultValue;
}
var_dump($a1);
Result:
array(2) {
[0] =>
array(3) {
'ID' =>
int(39)
'title' =>
string(5) "Apple"
'pages' =>
int(31)
}
[1] =>
array(3) {
'ID' =>
int(40)
'title' =>
string(6) "Orange"
'pages' =>
int(324)
}
}
Try this code :-
$newArray = array();
$i=0;
foreach($array1 as $value){
$newArray[$i] = $value;
$newArray[$i][] = $array2[$i];
$i++;
}
Here is code that produce exactly output you are looking for :
<?php
$list1 = array(array('id' => 39,'title' => 'Apple'),array('id' => 40,'title' => 'Orange'));
$list2 = array(array('pages' => 273,'year' => 1981),array('pages' => 386,'year' => 1979));
$newList = array();
$i=0;
foreach($list1 as $firstList){
foreach($list2 as $secondList){
$newList[$i] = array_merge($firstList, $secondList);

OUTPUT :
Try this
array1[0][pages]=array2[0][pages];
array1[0][year]=array2[0][year];
array1[1][pages]=array2[1][pages];
array1[1][year]=array2[1][year];
for($i=0; $i<count($array1); ++$i){
$array1[$i]['pages'] = $array2[$i];
}
var_dump($array1);
$output = array();
array_walk( $array1, function( $v, $k ) use ( $array2, &$output ) {
$output[] = array_merge( $v, $array2[$k] );
});
If the sizes of the 2 arrays are same you could do something like this
$arr1 = array(
array(
'ID' => 39,
'title' => 'Apple'
),
array(
'ID' => 40,
'title' => 'Orange'
)
);
$arr2 = array(
273,
386
);
$merged = array();
for ($i = 0; $i < count($arr1); $i++) {
$merged[] = array_merge($arr1[$i], array('pages' => $arr2[$i]));
}
var_dump($merged);
or if you don't want a new array
for ($i = 0; $i < count($arr1); $i++) {
$arr1[$i]['pages'] = $arr2[$i];
}
