Let's say I have an array and I want to search for a value should return multiple results:
array(2) {
[0] => array(2) {
["id"] => string(2) "1"
["custom"] => string(1) "2"
}
[1] => array(2) {
["id"] => string(2) "2"
["custom"] => string(1) "5"
}
[2] => array(2) {
["id"] => string(2) "3"
["custom"] => string(1) "2"
}
}
I want to search for key custom with value = 2, with the following result:
array(2) {
[0] => array(2) {
["id"] => string(2) "1"
["custom"] => string(1) "2"
}
[1] => array(2) {
["id"] => string(2) "3"
["custom"] => string(1) "2"
}
}
Is this possible without looping through array? Is there such class or built in function for this?
You could use:
array_values( array_filter($array, function($item) { return $item['custom'] == 2; }) );
array_values($array) is used to return an array with indexes which is consecutive, i.e. from 0, 1, 2, ... upward.
the array_filter function is probably what you want.
$array = [
[
'id' => '1',
'custom' => '2'
],
[
'id' => '2',
'custom' => '5'
],
[
'id' => '3',
'custom' => '2'
]
];
$customs = array_filter(
$array,
function ($arr) {
return is_array($arr) && array_key_exists('custom', $arr) && $arr['custom'] === '2';
}
);
You could simply remove the values you don't want by un-setting them from the array:
foreach($array as $key => $item) {
if($item['custom'] !== 2) {
unset($array[$key]);
}
}
Example
This is an alternative to array_values(), but essentially does it the same way.

I want to merge two different array data in one array, but i'm confuse how to use array_push in this case.
this is example of my data input:
["author"]=>
array(2) {
[0]=>
string(1) "John"
[1]=>
string(1) "Doe"
}
["title"]=>
array(2) {
[0]=>
string(1) "book a"
[1]=>
string(1) "book b"
}
And the result in one array that i mean, like this:
["books"]=>
array(2) {
[0] =>
array(2) {
["author"]=>
string(1) "John"
["title"]=>
string(1) "book a"
}
[1] =>
array(2) {
["author"]=>
string(1) "Doe"
["title"]=>
string(1) "book b"
}
}
I already try using this way but it just return 1 from each array:
$data['books'] = [];
array_push($data['books'], [
'author' => $data['author'],
'title' => $data['title']
]);
if (isset($data['books'])) {
foreach ($data['books'] as $k => $v) {
$data['books'][$k]['author'] = (int)$v['author'];
$data['books'][$k]['title'] = (int)$v['title'];
}
}
result:
["books"]=>
array(1) {
[0]=>
array(2) {
["author"]=>
int(1)
["title"]=>
int(1)
}
}
You have to transpose your arrays with the keys in mind.
function transpose(array $arr){
$transArr = [];
foreach($arr as $keyRow => $subArr) {
foreach($subArr as $keyCol => $value) {
$transArr[$keyCol][$keyRow] = $value;
}
}
return $transArr;
}
This function can be used universally for similar problems. The function comes from this class.
How to use:
$input = [
"author"=> ["John","Doe"],
"title" => ["book a","book b"],
];
$books = transpose($input);
echo '<pre>';
var_export($books);
Or if you want to use the class:
$books = tableArray::create($input)
->transpose()
->fetchAll()
;
Output:
array (
0 =>
array (
'author' => 'John',
'title' => 'book a',
),
1 =>
array (
'author' => 'Doe',
'title' => 'book b',
),
)
If "author" and "title" exist as two arrays, $ input must first be created like this:
$input = ['author' => $arrayAuthor, 'title' => $arrayTitle];
I have this multidimensional array:
array(3) {
[0]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(2)
}
[1]=>
array(2) {
["casestatus"]=> string(7) "Pending"
["casestatus_count"]=> int(1)
}
[2]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(1)
}
}
From the array above I am able to merge based on the casestatus key as shown below:
$newArray = array();
foreach($mergedData as $data)
{
if(!isset($newArray[$data["casestatus"]]))
{
$newArray[$data["casestatus"]] = array(
"casestatus" => $data["casestatus"],
"casestatus_count" => 0
);
}
$newArray[$data["casestatus"]]["casestatus_count"] += $data["casestatus_count"];
}
var_dump($newArray);
From which I get:
array(2) {
["Open"]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(3)
}
["Pending"]=>
array(2) {
["casestatus"]=> string(7) "Pending"
["casestatus_count"]=> int(1)
}
}
Note how my array keys are my casestatus. So is there a way of not having this and instead have my array keys as:
array(2) {
[0]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(3)
}
[1]=>
array(2) {
["casestatus"]=> string(7) "Pending"
["casestatus_count"]=> int(1)
}
}
Just do array_values($newArray) after the process.
var_dump(array_values($newArray));
array_values()
You could create a map of status to counts, then sum them:
<?php
$tickets =
[
[
'status' => 'Open',
'count' => 2
],
[
'status' => 'Closed',
'count' => 1
],
[
'status' => 'Open',
'count' => 1
]
];
foreach($tickets as $ticket)
$status_counts[$ticket['status']][] = $ticket['count'];
foreach($status_counts as $status => $counts)
$result[] = [
'status' => $status,
'count' => array_sum($counts)
];
var_export($result);
Output:
array (
0 =>
array (
'status' => 'Open',
'count' => 3,
),
1 =>
array (
'status' => 'Closed',
'count' => 1,
),
)
However a simpler format may suffice:
$result = array_map('array_sum', $status_counts);
var_export($result);
Output:
array (
'Open' => 3,
'Closed' => 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 associative array like this
$min_stats=
array(2)
{
[0]=> array(3)
{
["minute"]=> object(MongoInt64)#13 (1)
{
["value"]=> string(8) "10"
}
["add"]=> object(MongoInt64)#14 (1)
{
["value"]=> string(1) "9"
}
["tag"]=> object(MongoInt64)#15 (1)
{
["value"]=> string(1) "4"
}
}
[1]=> array(3)
{
["minute"]=> object(MongoInt64)#13 (1)
{
["value"]=> string(8) "11"
}
["add"]=> object(MongoInt64)#14 (1)
{
["value"]=> string(1) "9"
}
["tag"]=> object(MongoInt64)#15 (1)
{
["value"]=> string(1) "5"
}
}
} Array
Now I want to combine all the key-value pair in the array to get one array.
The resulting array should be
array(11)
{
["minute"]=> int(21)
["add"]=> int(18)
["tag"]=> int(9)
} Array
so for what I have written is
foreach ($min_stats as $k=>$subArray) {
foreach ($subArray as $id=>$value) {
$sumArray[$id]+=$value;
}
}
but its not giving me correct results, I don't know what I'm doing wrong?
The $value is coming as 2 means its just counting the elements in the subarray.
Thanks in advance for the help.
You can do it like this:
$finalArr = array();
foreach($array as $k1 => $v1){
foreach($v1 as $k2=>$v2){
if(!isset($finalArr[$k2])){
$finalArr[$k2] = 0;
}
$finalArr[$k2] += $v2['value'];
}
}
print_r($finalArr);
Output:
Array
(
[minute] => 21
[add] => 18
[tag] => 9
)
Easy copy array for testing:
$array = array(
array(
'minute' => array(
'value' => '10'
),
'add' => array(
'value' => '9'
),
'tag' => array(
'value' => '4'
),
),
array(
'minute' => array(
'value' => '11'
),
'add' => array(
'value' => '9'
),
'tag' => array(
'value' => '5'
),
)
);
