I have an array of data like this that is passed to my controller via a form. It's being collected in a javascript function. It will always be email the name but there could be 2 sets or 100.
array:10 [▼
0 => "ken#email.com"
1 => "Ken"
2 => "robert#email.com"
3 => "Robert"
4 => "robert#email.com"
5 => "Robert"
6 => "mike#email.com"
7 => "Mike"
]
I'm currently doing this
$recipients = array_chunk($recipients, 2);
array:5 [▼
0 => array:2 [▼
0 => "ken#email.com"
1 => "Ken"
1 => array:2 [▼
0 => "robert#email.com"
1 => "Robert"
2 => array:2 [▼
0 => "robert#email.com"
1 => "Robert"
3 => array:2 [▼
0 => "mike#email.com"
1 => "Mike"
]
What I need though is this...
array:5 [▼
0 => array:2 [▼
email => "ken#email.com"
name => "Ken"
1 => array:2 [▼
email => "robert#email.com"
name => "Robert"
2 => array:2 [▼
email => "robert#email.com"
name => "Robert"
3 => array:2 [▼
email => "mike#email.com"
name => "Mike"
]
How? Thanks!
You can re-add the value back to the array with a key and remove its duplicate by the index.
$recipients = array(
0 => "ken#email.com",
1 => "Ken",
2 => "robert#email.com",
3 => "Robert",
4 => "robert#email.com",
5 => "Robert",
6 => "mike#email.com",
7 => "Mike"
);
$recipients = array_chunk($recipients, 2);
for ($i=0; $i < count($recipients); $i++)
{
$recipients[$i]['email'] = $recipients[$i][0];
$recipients[$i]['name'] = $recipients[$i][1];
unset($recipients[$i][0]);
unset($recipients[$i][1]);
}
It would result in the following output:
Array
(
[0] => Array
(
[email] => ken#email.com
[name] => Ken
)
[1] => Array
(
[email] => robert#email.com
[name] => Robert
)
[2] => Array
(
[email] => robert#email.com
[name] => Robert
)
[3] => Array
(
[email] => mike#email.com
[name] => Mike
)
)
I hope it helped you.
Yes you can do that.
<?php
$array = array(
"foo" => "bar",
"bar" => "foo",
100 => -100,
-100 => 100,
);
var_dump($array);
?>
add to an array with custom key
<?php
$array= array();
$array[]='name=>bob';
var_dump($array);

I have 2 arrays
Array 1:
array:3 [▼
0 => 1
1 => 2.3
2 => 4.5
]
Array 2:
array:3 [▼
0 => array:2 [▼
"name" => "john"
"age" => 34
]
1 => array:2 [▼
"name" => "doe"
"age" => 12
]
2 => array:2 [▼
"name" => "kelvin"
"age" => 14
]
]
How do I merge array 1 into array 2 so that I have something like this-
array:3 [▼
0 => array:3 [▼
"name" => "john"
"age" => 34,
"score" => 1
]
1 => array:3 [▼
"name" => "doe"
"age" => 12,
"score" => 2.3
]
2 => array:3 [▼
"name" => "kelvin"
"age" => 14,
"score" => 4.5
]
]
Notice that the values of array 1 now have keys called 'score'.
You can use foreach loop with reference &:
$ar = [1,2,3.4];
$ar2 = [['name'=>'Joe','age' => 33],['name'=>'Joe2','age' => 33],['name'=>'Joe3','age' => 33]];
foreach($ar2 as $ind=>&$person){
$person['score'] = $ar[$ind];
}
print_r($ar2);
Demo
Output:
Array
(
[0] => Array
(
[name] => Joe
[age] => 33
[score] => 1
)
[1] => Array
(
[name] => Joe2
[age] => 33
[score] => 2
)
[2] => Array
(
[name] => Joe3
[age] => 33
[score] => 3.4
)
)
You can also use array_walk to walk through the array.
<?php
$a = [1,2.3,4.5];
$b = [
["name" => "john", "age" => 34],
["name" => "doe","age" => 12],
["name" => "kelvin", "age" => 14]
];
array_walk($a,function($val,$key) use (&$b){
$b[$key]['score'] = $val;
});
print_r($b);

I'm facing issue while dealing with 2 associative arrays. I have two arrays, If id of Array 1 = id of Array 2 = id, then active_lession and active_learning_lession of Array 1 should be replaced by active_lession and active_learning_lession of Array 2 respectively.
Array 1 =>
array:3 [
0 => array:10 [
"id" => 3
"status" => "1"
"active_lession" => 0
"active_learning_lession" => 0
"learninglessions" => array:2 [
0 => array:12 [
"id" => 2
"language_id" => 1
"category_id" => 3
"sentence" => "अगर आपको अपना स्कूल का नाम पुछा जाए तो क्या कहेंगे"
"english_sentence" => "I am student of …… School."
]
1 => array:12 [
"id" => 27
"language_id" => 1
"category_id" => 3
"sentence" => "यह मेरा दोस्त/मित्र है"
"english_sentence" => "He is my friend."
]
]
]
1 => array:10 [
"id" => 4
"name" => "Module 2"
"image" => "public/icon/downloadxxx.jpeg"
"status" => "1"
"active_lession" => 10
"active_learning_lession" => 0
"learninglessions" => array:2 [
0 => array:12 [
"id" => 1
"language_id" => 1
"category_id" => 4
"sentence" => "अपना परिचय कैसे देंगे –"
"english_sentence" => "I am..."
]
]
]
2 => array:10 [
"id" => 5
"status" => "1"
"active_lession" => 0
"active_learning_lession" => 0
"learninglessions" => array:4 [
0 => array:12 [
"id" => 29
"language_id" => 1
"category_id" => 5
"sentence" => "यह एक बाग है ।"
"english_sentence" => "This is a Park."
]
1 => array:12 [
"id" => 34
"language_id" => 1
"category_id" => 5
"sentence" => "कैसा चल रहा है ?"
"english_sentence" => "How are things ?"
]
]
]
Array 2=>
array:3 [
0 => array:3 [
"id" => 3
"active_learning_lession" => 25
"active_lession" => 20
]
1 => array:3 [
"id" => 4
"active_learning_lession" => 20
"active_lession" => 15
]
]
Thus Expected Array will be
array:3 [
0 => array:10 [
"id" => 3
"status" => "1"
"active_lession" => 20
"active_learning_lession" => 25
"learninglessions" => array:2 [
0 => array:12 [
"id" => 2
"language_id" => 1
"category_id" => 3
"sentence" => "अगर आपको अपना स्कूल का नाम पुछा जाए तो क्या कहेंगे"
"english_sentence" => "I am student of …… School."
]
1 => array:12 [
"id" => 27
"language_id" => 1
"category_id" => 3
"sentence" => "यह मेरा दोस्त/मित्र है"
"english_sentence" => "He is my friend."
]
]
]
1 => array:10 [
"id" => 4
"name" => "Module 2"
"image" => "public/icon/downloadxxx.jpeg"
"status" => "1"
"active_lession" => 15
"active_learning_lession" => 20
"learninglessions" => array:2 [
0 => array:12 [
"id" => 1
"language_id" => 1
"category_id" => 4
"sentence" => "अपना परिचय कैसे देंगे –"
"english_sentence" => "I am..."
]
]
]
2 => array:10 [
"id" => 5
"status" => "1"
"active_lession" => 0
"active_learning_lession" => 0
"learninglessions" => array:4 [
0 => array:12 [
"id" => 29
"language_id" => 1

1 => array:12 [
"id" => 34
"language_id" => 1
"category_id" => 5
"sentence" => "कैसा चल रहा है ?"
"english_sentence" => "How are things ?"
]
]
]
Try this code..
$res = [];
foreach($x as $key => $xx)
{
foreach($y as $k => $yy)
{
if($xx['id'] == $yy['id'])
{
$res[$key] = $xx;
$res[$key]['active_lession'] = $yy['active_lession'];
$res[$key]['active_learning_lession'] = $yy['active_learning_lession'];
}
else
{
if(!array_key_exists($key,$res))
{
$res[$key] = $xx;
}
}
}
}
print_r($res);
OR
foreach($x as $key => $value)
{
foreach($y as $yy)
{
if($value['id'] == $yy['id'])
{
$x[$key]['active_learning_lession'] = $yy['active_learning_lession'];
$x[$key]['active_lession'] = $yy['active_lession'];
}
}
}
print_r($x);
Output will be

I have an array of array, I would like to sort it base on the number in each array
[
["Plastic and cosmetic surgery",90],
["Dermatology surgery",121],
["Infertility",134],
["Gynecology surgery",191],
["Hair transplant",92],
["Bariatrics and weight loss surgery",117],
["Dentistry",88]
]
There is an amazing and simple default laravel solution for this.
$collection = collect([
["Plastic and cosmetic surgery",90],
["Dermatology surgery",121],
["Infertility",134],
["Gynecology surgery",191],
["Hair transplant",92],
["Bariatrics and weight loss surgery",117],
["Dentistry",88]
]);
$sorted = $collection->sortBy(1);
$data = $sorted->values()->all();
dd($data);
Output
array:7 [▼
0 => array:2 [▼
0 => "Dentistry"
1 => 88
]
1 => array:2 [▼
0 => "Plastic and cosmetic surgery"
1 => 90
]
2 => array:2 [▼
0 => "Hair transplant"
1 => 92
]
3 => array:2 [▼
0 => "Bariatrics and weight loss surgery"
1 => 117
]
4 => array:2 [▼
0 => "Dermatology surgery"
1 => 121
]
5 => array:2 [▼
0 => "Infertility"
1 => 134
]
6 => array:2 [▼
0 => "Gynecology surgery"
1 => 191
]
]
You can check more functions like this in the documentation. I hope you will enjoy this solution.
Try this to sorting value by number.

]
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
)

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
)
)
