I have an array like:
[0]=>
array(2) {
["item_name_en"]=>
string(7) "Salad 1"
["item_description"]=>
string(3) "Yum"
}
[1]=>
array(2) {
["item_name"]=>
string(7) "Salad 2"
["item_description"]=>
string(0) "Yum"
}
And another array like:
[0]=>
array(2) {
["price"]=>
string(2) "15"
}
[1]=>
array(2) {
["price"]=>
string(2) "25"
}
How do I merge them both into 1 array where the result looks like:
array(3) {
["item_name_en"]=>
string(7) "Salad 1"
["item_description"]=>
string(3) "Yum"
["price"]=>
string(2) "15"
}
They will always be the same length but never have the same keys. I already tried array_merge and also $result = $array1 + $array2; but that did not produce the desired result. There must be an easy way for this?
You can do it this way:
Initial data
$a = [
[
"item_name_en"=> "Salad 1",
"item_description"=> "Yum"
],
[
"item_name"=> "Salad 2",
"item_description"=> "Yum"
]
];
$b = [
[
"price"=> "15"
],
[
"price"=> "25"
]
];
Result
$c = []; //New array
foreach($a as $k => $v){
$c[$k] = array_merge($a[$k], $b[$k]);
}
Output
array (size=2)
0 =>
array (size=3)
'item_name_en' => string 'Salad 1' (length=7)
'item_description' => string 'Yum' (length=3)
'price' => string '15' (length=2)
1 =>
array (size=3)
'item_name' => string 'Salad 2' (length=7)
'item_description' => string 'Yum' (length=3)
'price' => string '25' (length=2)

I have couple of arrays like this
$arrayOne = array (
"name" => 'john',
"position" => 'instructor',
"hired" => '2010',
"department" => 'math',
);
$arrayTwo = array (
"name" => 'smith',
"position" => 'instructor',
"hired" => '2010',
"department" => 'math',
);
$arrayThree = array (
"name" => 'dave',
"position" => 'instructor',
"hired" => '2009',
"department" => 'math',
);
how can I check if these arrays all have the same hired date?
one way would be compare each individual one:
if($arrayOne['hired'] === $arrayTwo['hired']) & if($arrayOne['hired'] === $arrayThree['hired']) & ...
but is there a cleaner way to do this?
Your initial question and subsequent comment are similar but they are attempting to do different things with the data, with different outcomes. The initial as-asked was:
how can I check if these arrays all have the same hired date
And that can be done with the following:
var_dump(count(array_unique(array_column([$arrayOne, $arrayTwo, $arrayThree], 'hired'))));
// or
$combined = [$arrayOne, $arrayTwo, $arrayThree];
$hiredValues = array_column($combined, 'hired');
$hiredValuesUnique = array_unique($hiredValues);
$length = count($hiredValuesUnique);
var_dump($length);
If the count is 1, they are the same, otherwise they aren't.
But, your follow-up comment was
how can I know which ones are the same
To do that, I'd create a new array that is keyed by that value, and foreach over the source arrays, effectively grouping similar ones for you to further act up.
$final = [];
foreach([$arrayOne, $arrayTwo, $arrayThree] as $array){
if(!array_key_exists($array['hired'], $final)){
$final[$array['hired']] = [];
}
$final[$array['hired']][] = $array;
}
var_dump($final);
Which produces:
array(2) {
[2010]=>
array(2) {
[0]=>
array(4) {
["name"]=>
string(4) "john"
["position"]=>
string(10) "instructor"
["hired"]=>
string(4) "2010"
["department"]=>
string(4) "math"
}
[1]=>
array(4) {
["name"]=>
string(5) "smith"
["position"]=>
string(10) "instructor"
["hired"]=>
string(4) "2010"
["department"]=>
string(4) "math"
}
}
[2009]=>
array(1) {
[0]=>
array(4) {
["name"]=>
string(4) "dave"
["position"]=>
string(10) "instructor"
["hired"]=>
string(4) "2009"
["department"]=>
string(4) "math"
}
}
}
I have written the code below:
//Your data
$arrayOne = array (
"name" => 'john',
"position" => 'instructor',
"hired" => '2010',
"department" => 'math',
);
$arrayTwo = array (
"name" => 'smith',
"position" => 'instructor',
"hired" => '2010',
"department" => 'math',
);
$arrayThree = array (
"name" => 'dave',
"position" => 'instructor',
"hired" => '2009',
"department" => 'math',
);
function hiredIsTheSameEverywhere(...$arrays) : bool
{
return count(array_count_values(array_column($arrays, "hired"))) === 1;
}
function whereHiredIsTheSame(...$arrays) : array
{
$return = [];
$count = array_count_values(array_column($arrays, "hired"));
foreach($arrays as $array) {
if($count[$array['hired']] > 1) {
$return[$array['hired']][] = $array;
}
}
return $return;
}
//The output
var_dump(hiredIsTheSameEverywhere($arrayOne, $arrayTwo, $arrayThree));
var_dump(whereHiredIsTheSame($arrayOne, $arrayTwo, $arrayThree));
output:
bool(false)
array(1) {

I have an array with 4 data each, what i want to accomplish is to remove
value of duplicate/equal tag_id and put/append the tag_images together
of the same tag_id. I also used array_unique but i don't know where to put it.
My array has a tag_id,tag_slug,tag_color, and tag_images(array). The last 2 array have the same data except with tag_images, I want to merge those data as one and put the tag_images in an array.
example:
array(4) {
[0]=>
array(4) {
["tag_id"]=> int(25)
["tag_slug"]=> string(5) "green"
["tag_color"]=> string(7) "#81d742"
["tag_images"]=> array(1) {
[0]=> string(75) "http://localhost/mysite/wp-content/uploads/2018/08/long-sleeve-tee.jpg"
}
}
[1]=>
array(4) {
["tag_id"]=> int(23)
["tag_slug"]=> string(3) "red"
["tag_color"]=> string(7) "#dd3333"
["tag_images"]=> array(1) {
[0]=> string(69) "http://localhost/mysite/wp-content/uploads/2018/08/vneck-tee.jpg"
}
}
[2]=>
array(4) {
["tag_id"]=> int(23)
["tag_slug"]=> string(3) "red"
["tag_color"]=> string(7) "#dd3333"
["tag_images"]=> array(1) {
[0]=> string(66) "http://localhost/mysite/wp-content/uploads/2018/08/beanie.jpg"
}
}
}
Output:
array(4) {
[0]=>
array(4) {
["tag_id"]=>
int(25)
["tag_slug"]=>
string(5) "green"
["tag_color"]=>
string(7) "#81d742"
["tag_images"]=>
array(1) {
[0]=>
string(75) "http://localhost/mysite/wp-content/uploads/2018/08/long-sleeve-tee.jpg"
}
}
[1]=>
array(4) {
["tag_id"]=>
int(23)
["tag_slug"]=>
string(3) "red"
["tag_color"]=>
string(7) "#dd3333"
["tag_images"]=>
array(1) {
[0]=>
string(66) "http://localhost/mysite/wp-content/uploads/2018/08/beanie.jpg"
[1]=>
string(69) "http://localhost/mysite/wp-content/uploads/2018/08/vneck-tee.jpg"
}
}
}
You can use array_merge_recursive()
Or use this function from this answer
function my_array_merge(&$array1, &$array2) {
$result = Array();
foreach($array1 as $key => &$value) {
$result[$key] = array_merge($value, $array2[$key]);
}
return $result;
}
$array = my_array_merge($array1, array2);
print_r($array);
I'd iterate the main array and build a second one.
$mainArray = array
(
array("tag_id" => 25,
"tag_slug" => "green",
"tag_color" => "#81d742",
"tag_images" => array("http://localhost/mysite/wp-content/uploads/2018/08/long-sleeve-tee.jpg")
),
array("tag_id" => 23,
"tag_slug" => "red",
"tag_color" => "#dd3333",
"tag_images" => array("http://localhost/mysite/wp-content/uploads/2018/08/vneck-tee.jpg")
),
array("tag_id" => 23,
"tag_slug" => "red",
"tag_color" => "#dd3333",
"tag_images" => array("http://localhost/mysite/wp-content/uploads/2018/08/beanie.jpg")
)
);
$freshArray = array();
foreach ($mainArray as $value)
{
$key = array_search($value['tag_id'], array_column($freshArray, 'tag_id'));
if (false === $key)
$freshArray[] = $value;
else
$freshArray[$key]['tag_images'][] = $value['tag_images'][0];
}
var_dump($freshArray);
Output :
array (size=2)
0 =>
array (size=4)
'tag_id' => int 25
'tag_slug' => string 'green' (length=5)
'tag_color' => string '#81d742' (length=7)
'tag_images' =>
array (size=1)
0 => string 'http://localhost/mysite/wp-content/uploads/2018/08/long-sleeve-tee.jpg' (length=70)
1 =>
array (size=4)
'tag_id' => int 23
'tag_slug' => string 'red' (length=3)
'tag_color' => string '#dd3333' (length=7)
'tag_images' =>
array (size=2)
0 => string 'http://localhost/mysite/wp-content/uploads/2018/08/vneck-tee.jpg' (length=64)
1 => string 'http://localhost/mysite/wp-content/uploads/2018/08/beanie.jpg' (length=61)
I have array mentioned below, I will have value always multiple of 3.
$xyz = [
["name" => "abc"],
["name" => "snds"],
["name" => ""),
["number"=> "452"],
["number" => "845120"],
["number" => "84514513200"],
["email" => "ddddf"],
["email" => "dkskns"],
["email" => "kjnksdnkds"]
];
but this is not the proper format for me to perform further operations, so I want this array like mentioned below.
$abc = [
[
"name" => "abc",
"number" => '452',
"email" => "ddddf"
],
[
"name" => "snds",
"number" => "845120",
"email" => "dkskns"
],
[
"name" => "",
"number" => "84514513200",
"email" => "kjnksdnkds"
]
];
note: the array length is dynamic but it will always be multiple of 3
One possibility could be to use the modulo % operator.
In the foreach the value is an array and you could use array_keys to get the key and reset to get the value of the first array element.
$result = [];
$count = 0;
foreach ($xyz as $value) {
if ($count%3 === 0) {
$count = 0;
}
$result[$count][array_keys($value)[0]] = reset($value);
$count++;
}
Demo
That will give you:
array(3) {
[0]=>
array(3) {
["name"]=>
string(3) "abc"
["number"]=>
string(3) "452"
["email"]=>
string(5) "ddddf"
}
[1]=>
array(3) {
["name"]=>
string(4) "snds"
["number"]=>
string(6) "845120"
["email"]=>
string(6) "dkskns"
}
[2]=>
array(3) {
["name"]=>
string(0) ""
["number"]=>
string(11) "84514513200"
["email"]=>
string(10) "kjnksdnkds"
}
}
This will do:
$result = array_map('array_merge', ...array_chunk($xyz, count($xyz) / 3));
I have an array like this. I want remove elements with duplicate id and get sum of the count
array(3) {
[0]=>
array(3) {
["Id"]=>
string(1) "1"
["Name"]=>
string(1) "a"
["Count"]=>
string(1) "2"
}
[1]=>
array(3) {
["Id"]=>
string(1) "2"
["Name"]=>
string(1) "b"
["Count"]=>
string(1) "1"
}[2]=>
array(3) {
["Id"]=>
string(1) "1"
["Name"]=>
string(1) "a"
["Count"]=>
string(1) "1"
}
}
and I need to remove elements with duplicate id and get sum of the count as shown below
array(2) {
[0]=>
array(3) {
["Id"]=>
string(1) "1"
["Name"]=>
string(1) "a"
["Count"]=>
string(1) "3"
}[1]=>
array(3) {
["Id"]=>
string(1) "2"
["Name"]=>
string(1) "b"
["Count"]=>
string(1) "1"
}
}
I have gone through many examples.. but couldn't find an answer..
Unfortunately there is no way around looping. Assuming that Name is the same for the same Id or that you don't care about the value of Name:
foreach($array as $value) {
if(!isset($result[$value['Id']])) {
$result[$value['Id']] = $value;
} else {
$result[$value['Id']]['Count'] += $value['Count'];
}
}
// re-index if needed
$result = array_values($result);
Loop the array and build result array using Id as key
If the key Id doesn't exist create it
If it does exist add Count to the current Count
just create a new array, loop through current, create if doesnt exist, and insert values (sum) into new one
what are you doing with duplicates names?
example below. hope it will help.
<?php
$tArr = array(
array(
"Id" => "1",
"Name" => "a",
"Count" => "2",
),
array(
"Id" => "2",
"Name" => "b",
"Count" => "1",
),
array(
"Id" => "1",
"Name" => "a",
"Count" => "1",
)
);
$rez = array();
foreach ($tArr as $key => $element) {
if (empty($rez[$element["Id"]])) {
$rez[$element["Id"]] = $element;
} else {
$rez[$element["Id"]]["Count"] += $element["Count"];
}
}
var_dump($rez);
/** array (size=2)
1 =>
array (size=3)
'Id' => string '1' (length=1)
'Name' => string 'a' (length=1)
'Count' => int 3
2 =>
array (size=3)
'Id' => string '2' (length=1)
'Name' => string 'b' (length=1)
'Count' => string '1' (length=1)**/
Try this
$result = array_diff_assoc($arr, array_unique($arr));
print_r($result);
i got an array like this:
array
'list_10' =>
array
row_0 =>
array
'Id' => string '118579'
'Status' => string '3'
row_1 =>
array
'Id' => string '117662'
'Status' => string '2'
row_2 =>
array
'Id' => string '117662'
'Status' => string '2'
'list_11' =>
array
row_0 =>
array
'Id' => string '112564'
'Status' => string '2'
row_1 =>
array
'Id' => string '153622'
'Status' => string '3'
row_2 =>
array
'Id' => string '112832'
'Status' => string '1'
i want to "natsort" the first key "list_XX", making it start with 0,1,2,.. instead of 10,11,12,13,0,1,2,3,...
i played around with array_multisort but i cant seem to
set the right params to make it do what i want, if its even capable of doing this.
any advice?
Assuming your array is something like this:
$array = [
'list_11' =>
[
'row_0' =>
[
'Id' => '118579',
'Status' => '3'
],
'row_1' =>
[
'Id' => '117662',
'Status' => '2'
],
'row_2' =>
[
'Id' => '117662',
'Status' => '2'
]
],
'list_10' =>
[
'row_0' =>
[
'Id' => '112564',
'Status' => '2'
],
'row_1' =>
[
'Id' => '153622',
'Status' => '3'
],
'row_2' =>
[
'Id' => '112832',
'Status' => '1'
]
],
'list_1' =>
[
'row_0' =>
[
'Id' => '32323232',
'Status' => '3'
],
'row_1' =>
[
'Id' => '2353333',
'Status' => '2'
],
'row_2' =>
[
'Id' => '117662',
'Status' => '2'
]
]
];
Using array_multisort :
$sort = [];
foreach($array as $el=>$val){
$sort[] = $el;
}
array_multisort($array,SORT_NUMERIC,$sort,SORT_NATURAL);
var_dump($array);
Will print :
array(3) {
["list_1"]=>
array(3) {
["row_0"]=>
array(2) {
["Id"]=>
string(8) "32323232"
["Status"]=>
string(1) "3"
}
["row_1"]=>
array(2) {
["Id"]=>
string(7) "2353333"
["Status"]=>
string(1) "2"
}
["row_2"]=>
array(2) {
["Id"]=>
string(6) "117662"
["Status"]=>
string(1) "2"
}
}
["list_10"]=>
array(3) {
["row_0"]=>

["Id"]=>
string(6) "112832"
["Status"]=>
string(1) "1"
}
}
["list_11"]=>
array(3) {
["row_0"]=>
array(2) {
["Id"]=>
string(6) "118579"
["Status"]=>
string(1) "3"
}
["row_1"]=>
array(2) {

}
["row_2"]=>
