I was searching around but still I can't find an answer.
I have following array
array:2 [
0 => array:2 [
0 => "Name"
1 => "Age"
]
1 => array:2 [
0 => "Name"
1 => "Age"
]
]
and I want to add new value 0 in all arrays. This is the result I expect.
array:2 [
0 => array:2 [
0 => "Name"
1 => "Age"
2 => 0
]
1 => array:2 [
0 => "Name"
1 => "Age"
2 => 0
]
]
Thank you.
Try something like.
foreach($array as &$subArray) {
$subArray[] = 0;
}
var_dump($array);

I'm have the following array.
"rent" => array:3 [
0 => array:1 [
0 => "5000"
]
1 => array:3 [
0 => "10000"
1 => "60000"
2 => "80000"
]
2 => []
]
"house_quantity" => array:3 [
0 => array:1 [
0 => "2"
]
1 => array:3 [
0 => "3"
1 => "4"
2 => "6"
]
2 => []
]
"property_id" => array:3 [
0 => 1
1 => 2
2 => 3
]
"type_of_house" => array:3 [
0 => array:1 [
0 => array:1 [
"type" => "studio_apartment"
]
]
1 => array:3 [
0 => array:1 [
"type" => "studio_apartment"
]
1 => array:1 [
"type" => "one_bedroom"
]
2 => array:1 [
"type" => "two_bedroom"
]
]
2 => array:2 [
0 => array:1 [
"type" => "studio_apartment"
]
1 => array:1 [
"type" => "two_bedroom"
]
]
]
]
I want to combine the above array so that it forms an array that looks like this.
"0" => [
"property_id" => 1
"type_of_house" => array:3 [
"type"=> "studio_apartment"
"rent" => "5000"
"house_quantity" => "2"
]
]
"1" => [
"property_id" => 2
"type_of_house" => array:3 [
"type"=> "studio_apartment"
"rent" => "10000"
"house_quantity" => "3"
]
"type_of_house" => array:3 [
"type"=> "one_bedroom"
"rent" => "60000"
"house_quantity" => "4"
]
"type_of_house" => array:3 [
"type"=> "two_bedroom"
"rent" => "80000"
"house_quantity" => "6"
]
]
So far I'm using the foreach loop to loop over the properties and attach the type of houses in each of those properties as follows:
foreach ($request->property_id as $key=> $property_id) {
$result[$key] = array(
'property_id' => $property_id,
'type_of_house' => $request->type_of_house[$key]
);
foreach ($result as $property_key => $property) {
foreach ($property['type_of_house'] as $house_key => $house) {
$house[$key][$house_key] = array(
'rent' => $request->rent[$key][$house_key],
'house_quantity' => $request->house_quantity[$key][$house_key]
);
}
}
$merge = array_merge_recursive($result, $house);
dd($merge);
}
But the array I'm getting back is not quite right. This is the array that I'm getting back.
array:3 [
0 => array:2 [
"property_id" => 1
"type_of_house" => array:1 [
0 => array:1 [
"type" => "studio_apartment"
]
]
]
"type" => "studio_apartment"
1 => array:1 [
0 => array:2 [
"rent" => "5000"
"house_quantity" => "2"
]
]
]
How do I correctly merge such an array, thanks.
Ok, so let's suppose you have 2 arrays
$array1:
Array(2){
[number] => 1,
[address] => "Park Ave 273",
[name] => "Peter Jones"
}
And then a clean $array2, the one i'm gonna be putting my info
To mix them i would have to specify the index i want the first array to get in, for example:
$array1 = array(
"number" => 1,
"address" => "Park Ave 273",
"name" => "Peter Jones"
);
$array2 = array();
$array2['client'] = $array1;
Would return:
Array
(
[client] => Array
(
[number] => 1
[address] => Park Ave 273
[name] => Peter Jones
)
)
In case you have more than one client (on this example) you have to do a foreach loop for every client.
I Would Like To Get The First Element Of This Array And Put In New Same Array Output
One Requirement: It Cannot Be Done With Passing By reference Index eg 0
This Input Array
[ 'id','ID','dt-text' ] ,
[ 'name','Name','dt-text' ] ,
[ 'artistList'=>['list','mm','defalut'] ,'Artist List','dt-select'] ,
[ 'nationality'=>['nationality','mm','defalut'] ,'Nationality','dt-select'] ,
[ 'view','View',''],
[ 'status','Status' ,'']
array:6 [▼
0 => array:3 [▼
0 => "id"
1 => "ID"
2 => "dt-text"
]
1 => array:3 [▼
0 => "name"
1 => "Name"
2 => "dt-text"
]
2 => array:3 [▼
"artistList" => array:3 [▼
0 => "list"
1 => "mm"
2 => "defalut"
]
0 => "Artist List"
1 => "dt-select"
]
3 => array:3 [▼
"nationality" => array:3 [▼
0 => "nationality"
1 => "mm"
2 => "defalut"
]
0 => "Nationality"
1 => "dt-select"
]
4 => array:3 [▼
0 => "view"
1 => "View"
2 => ""
]
5 => array:3 [▼
0 => "status"
1 => "Status"
2 => ""
]
]
The New Array I Needed
This IS OutPUT Array
['id','name','artistList'=>['list','mm','defalut'] ,'nationality'=>['nationality','mm','defalut'] ,'view','status']
array:6 [▼
0 => "id"
1 => "name"
"artistList" => array:3 [▼
0 => "list"
1 => "mm"
2 => "defalut"
]
"nationality" => array:3 [▼
0 => "nationality"
1 => "mm"
2 => "defalut"
]
2 => "view"
3 => "status"
]
Note
I Can Controll in Input Array Same , I Try with foreach in php And Tray In Laravel Helper Function head Put I get S
array:6 [▼
0 => "id"
1 => "name"
2 => array:1 [▼
"artistList" => array:3 [▼
0 => "list"
1 => "mm"
2 => "defalut"
]
]
3 => array:1 [▼
"nationality" => array:3 [▼
0 => "nationality"
1 => "mm"
2 => "defalut"
]
]
4 => "view"
5 => "status"
]
Put I Cant Get Resslut So , How Can I Do this?
Since you are changing the keys (structure) of the array, there is no way to do that without either generating a new array or passing the array by reference. One way to do it by generating a new array is with array_reduce:
$array = [
[ 'id','ID','dt-text' ] ,
[ 'name','Name','dt-text' ] ,
[ 'artistList'=>['list','mm','defalut'] ,'Artist List','dt-select'] ,
[ 'nationality'=>['nationality','mm','defalut'] ,'Nationality','dt-select'] ,
[ 'view','View',''],
[ 'status','Status' ,'']
];
$array = array_reduce($array, function ($c, $v) {
$first_key = array_keys($v)[0];
return array_merge($c, array($first_key => $v[$first_key])); }, []);
print_r($array);
Output:
Array (
[0] => id
[1] => name
[artistList] => Array (
[0] => list
[1] => mm
[2] => defalut
)
[nationality] => Array (
[0] => nationality
[1] => mm
[2] => defalut
)
[2] => view
[3] => status
)
Demo on 3v4l.org
I have a multidimensional array as
array:3 [▼
0 => array:3 [▼
"product_id" => "8"
"qty" => 1
]
1 => array:3 [▼
"product_id" => "9"
"qty" => 2
]
]
and I would like to merge a static associative array ['invoice_id' => 1] in to all the arrays in the multidimensional array. and the end result should be something like this
array:3 [▼
0 => array:3 [▼
"product_id" => "8"
"qty" => 1,
"invoice_id" => 1
]
1 => array:3 [▼
"product_id" => "9"
"qty" => 2,
"invoice_id" => 1
]
]
is there a way to do this with out looping through the multidimensional array
Try using Array_Map
suppose Array data store in $testArray variable
$testArray= array_map(function($arr){
return $arr + ['invoice_id' => 1];
}, $testArray);
Please how do i apply array_merge_recursive on the code below
<?php
array:4 [▼
0 => array:1 [▼
1 => "1_1"
]
1 => array:1 [▼
1 => "1_2"
]
2 => array:1 [▼
2 => "2_1"
]
3 => array:1 [▼
2 => "2_2"
]
]
?>
I need the output to be
<?php
array:2 [▼
0 => array:2 [▼
0 => "1_1",
1 => "1_2"
]
1 => array:2 [▼
0 => "2_1",
1 => "2_2"
]
]
?>
Note: the inner array might increase from 4 to 1000
Thank you.
Short and to the point.
$array = [
0 => [
0 => '1_1',
],
1=> [
0 => '1_2',
],
2 => [
0 => '2_1',
],
3 => [
0 => '2_2',
],
];
foreach(array_chunk($array, 2) as $value){
print_r(array_merge(array_shift($value), array_pop($value)));
}
Get a chunk of 2 from the big array. Loop over the chunks, get the first element in the array and the last element and merge them.
Result:
Array
(
[0] => 1_1
[1] => 1_2
)
Array
(
[0] => 2_1
[1] => 2_2
)
Remove the print_r and adapt to your own needs.
array_merge_recursive can also be used instead of array_merge but it this case it does exactly the same thing. You'd still need to somehow get the chunks.
After a lot of API calls and loops I have created an array. This array takes the following form
2 => array:3 [▼
"someInfo" => array:1 [▶]
"existingIDs" => array:1 [▼
0 => array:1 [▼
"id" => "123456"
]
]
"idList" => array:2 [▼
0 => array:1 [▼
"id" => "123456"
]
1 => array:1 [▼
"id" => "777564"
]
]
]
The part I am interested in is existingIDs and idList. The problem is that some ids are appearing in both array elements, so in the above example the id 123456 appears in both.
What I need to do is cross compare these two elements and perhaps create a new element with unique ids. So the above example may turn into something like this
2 => array:3 [▼
"someInfo" => array:1 [▶]
"existingIDs" => array:1 [▼
0 => array:1 [▼
"id" => "123456"
]
]
"idList" => array:2 [▼
0 => array:1 [▼
"id" => "123456"
]
1 => array:1 [▼
"id" => "777564"
]
]
"uniqueList" => array:2 [
0 => array:1 [
"id" => "123456"
]
1 => array:1 [
"id" => "777564"
]
]
]
How could something like this be achieved?
Thanks
Use the following approach with array_column(available since PHP 5.5), array_merge and array_unique functions:
$arr = [
"someInfo" => [],
"existingIDs" => [
["id" => "123456"]
],
"idList" => [
["id" => "123456"],
["id" => "777564"],
["id" => "777564"]
]
];
$all_ids = array_merge(array_column($arr['existingIDs'], 'id'), array_column($arr['idList'], 'id'));
$arr['uniqueList'] = array_unique($all_ids);
print_r($arr);
The output:
Array
(
[someInfo] => Array
(
)
[existingIDs] => Array
(
[0] => Array
(
[id] => 123456
)
)
[idList] => Array
(
[0] => Array
(
[id] => 123456
)
[1] => Array
(
[id] => 777564
)
[2] => Array
(
[id] => 777564
)
)
[uniqueList] => Array
(
[0] => 123456
[2] => 777564
)
)
