I have the following input array:
$arr = [
"quote_id" => "1",
"ONE" => "2018-03-12",
"TWO" => "2018-02-12",
"THREE" => "2018-01-12",
"FOUR" => "2017-12-12"
];
and I need to transform to the following output:
[
"quote_id" => "1",
"ONE" => "2018-03-12"
],
[
"quote_id" => "1",
"TWO" => "2018-02-12"
],
[
"quote_id" => "1",
"THREE" => "2018-01-12"
],
[
"quote_id" => "1",
"FOUR" => "2017-12-12"
]
The idea is to insert a record in the DB per each COLUMN (ONE, TWO, ...) so I end up with:
INSERT INTO table id=1, value="2018-03-12"
INSERT INTO table id=1, value="2018-02-12"
INSERT INTO table id=1, value="2018-01-12"
INSERT INTO table id=1, value="2017-12-12"
Can I get some help?
Aslong as quote_id is the key that you want inserted every time
foreach ($arr as $key => $value) {
if($key != "quote_id")
{
/* insert $arr["quote_id"], $value */
}
}

I'm trying to add 2 array data to each other with array_merge(). It's just attached to the back. But lower levels are ignored.
Is there an alternative to array_merge() that will merge the user values without duolicating the color values?
Existing array data:
$existingtArr = [
"A" => [
"color" => 'red',
"user" => [
"Daniel" => ["01:18:08", "04:10:12"],
"Max" => ["01:04:00"],
"Serto" => ["02:00:02"],
]
],
"B" => [
"color" => 'blue',
"user" => [
"Franz" => ["08:40:52"],
"Hugo" => ["07:08:58"],
]
]
];
New array data:
$newArr = [
"A" => [
"color" => 'red',
"user" => [
"Fabian" => ["06:03:00"], // + 1 user
"Max" => ["04:10:12"], // + 1 new time
"Serto" => ["02:00:02"],
]
],
"B" => [
"color" => 'blue',
"user" => [
"Franz" => ["08:40:52", "14:05:32", "20:34:15"], // an older one is available, + 2 new times
"Hugo" => ["04:10:12"], // + 1 time
]
],
"C" => [ // + new whole group
"color" => 'green',
"user" => [
"Maxi" => ["07:08:58", "04:10:12"],
]
]
];
Supplement the existing data with the new data:
echo '<pre>';
print_r(array_merge($existingtArr, $newArr));
echo '</pre>';
Expected result array data:
$resultArr = [
"A" => [
"color" => 'red',
"user" => [
"Daniel" => ["01:18:08", "04:10:12"],
"Fabian" => ["06:03:00"],
"Max" => ["01:04:00", "04:10:12"],
"Serto" => ["02:00:02"],
]
],
"B" => [
"color" => 'blue',
"user" => [
"Franz" => ["08:40:52", "14:05:32", "20:34:15"],
"Hugo" => ["07:08:58", "04:10:12"],
]
],
"C" => [
"color" => 'green',
"user" => [
"Maxi" => ["07:08:58", "04:10:12"],
]
]
];
You cannot simply call array_merge_recursive() on the whole data sets because they will generated repeated color values, but you want the color values to remain singular and the user data to be recursively merged.
To accommodate this logic (assuming it is okay to simply mutate the $existingtArr array with the data from $newArr), perform a check for the existence of each letter-set, and either push the whole set for a non-present letter, or recursively merge the shared letter-sets.
Code: (Demo)
foreach ($newArr as $letter => $set) {
if (!isset($existingtArr[$letter])) {
$existingtArr[$letter] = $set;
} else {
$existingtArr[$letter]['user'] = array_merge_recursive(
$existingtArr[$letter]['user'],
$set['user']
);
}
}
var_export($existingtArr);
This is the first problem:
I have two Associative Arrays, one containing sales persons and one containing clients.
$salesPersons = array(
array(
"id" => "1",
"name" => "Mr Smith",
"email" => "mrsmith#email.com",
"clients" => array()
),
array(
"id" => "2",
"name" => "James Bond",
"email" => "jamesbond#email.com",
"clients" => array()
)
);
$clients = array(
array(
"id" => "1",
"name" => "Lucifer Enterprises",
"salesPersonId" => "1"
),
array(
"id" => "2",
"name" => "Charlies Chocolate Factory",
"salesPersonId" => "1"
),
array(
"id" => "3",
"name" => "Geckos Investments",
"salesPersonId" => "2"
),
);
I want to map $salesPersons['id'] to clients['salesPersonId'] by ID and return a multidimensional associative array like this:
$result_i_want = array(
array(
"id" => "1",
"name" => "Mr Smith",
"email" => "mrsmith#email.com",
"clients" => array(
array(
"id" => "1",
"name" => "Lucifer Enterprises",
),
array(
"id" => "2",
"name" => "Charlies Chocolate Factory",
),
)
),
array(
"id" => "2",
"name" => "James Bond",
"email" => "jamesbond#email.com",
"clients" => array(
array(
"id" => "3",
"name" => "Geckos Investments",
),
)
)
);
My solution to the first problem
I have solved it using nested foreach-loops and array_push
$result = array();
foreach ($clients as $c_record) {
foreach ($salesPersons as $s_record) {
if ($c_record['salesPersonId'] == $s_record['id']) {
array_push($s_record['clients'], array(
"id" => $c_record['id'],
"name" => $c_record['name']
));
array_push($result, $s_record);
}
}
}
The remaining problem
This solution doesn't seem to be very efficient.
For each client record I check all sales persons to see if there is a match. I think the number of computations are:
no. of clients * no. of sales persons
I have a huge database and also need to add even more dimensions by mapping projects to the clients and deliverables to the projects. I think this could pose a problem.
Question
Is there a more efficient way to get the same result?
Build an index :
you need to access your salesPerson entries by id, you can start by creating an associative array id => salesPerson, and then use this associative array in your loop.
$salesById = array();
foreach ($salesPersons as $s_record) {
$salesById[ $s_record['id'] ] = $s_record;
}
$result = array();
foreach ($clients as $c_record) {
$s_record = $salesById[ $c_record['salesPersonId'] ];
if ($s_record == null) {
// you may want to handle invalid ids in the client array
// one way is to simply ignore this client record :
continue;
}
array_push($s_record['clients'], array(
"id" => $c_record['id'],
"name" => $c_record['name']
));
array_push($result, $s_record);
}
Notes
There may be a problem in the way you create your $result array :
if a sales person has n clients, the $result array will reference that sales person n times.
Look closer into what result you actually want, you may simply want to return $salesPersons, or $salesById.
As LeGEC said:
you need to access your salesPerson entries by id, you can start by creating an associative array id => salesPerson, and then use this associative array in your loop.
You need to set the index of your arrays with the id:
<?php
$salesPersons = array(
1 => array(
"id" => "1",
"name" => "Mr Smith",
"email" => "mrsmith#email.com",
"clients" => array()
),
2 => array(
"id" => "2",
"name" => "James Bond",
"email" => "jamesbond#email.com",
"clients" => array()
)
);
$clients = array(
1 => array(
"id" => "1",
"name" => "Lucifer Enterprises",
"salesPersonId" => "1"
),
2 => array(
"id" => "2",
"name" => "Charlies Chocolate Factory",
"salesPersonId" => "1"
),
3 => array(
"id" => "3",
"name" => "Geckos Investments",
"salesPersonId" => "2"
),
);
Then:
$result = array();
foreach ($clients as $id => $c_record) {
if (isset($salesPersons[$id])) {
$result[] = array_merge($clients[$id], $salesPersons[$id]);
} else {
$result[] = $clients[$id];
}
}
var_dump($result);
Result here: http://sandbox.onlinephpfunctions.com/code/e590bdb5aaea2794fc5a04ee60f61db766129664
PS:
My code works with your use case, but it will not work if the size of the $salesPersons array is bigger than the $clients array
I have a table from which i am fetching some columns
$records=Table::select('id','text','type')->paginate(250)->toArray();
$data=$records->['data'];
I am getting output as :-
array:250 [
0 => array:4 [
"id" => 1
"text" => "text1"
"type" => "A"
]
1 => array:4 [
"id" => 1
"text" => "text2"
"type" => "B"
]
2 => array:4 [
"id" => 1
"text" => "text3"
"type" => "C"
]
3 => array:4 [
"id" => 2
"text" => "text4"
"type" => "A"
]
4 => array:4 [
"id" => 2
"text" => "text5"
"type" => "B"
]
5 => array:4 [
"id" => 2
"text" => "text6"
"type" => "C"
]
6 => array:4 [
"id" => 3
"text" => "text7"
"type" => "A"
]
7 => array:4 [
"id" => 3
"text" => "text8"
"type" => "B"
]
8 => array:4 [
"id" => 3
"text" => "text9"
"type" => "C"
]....
]
I want to convert it into array of objects/array of arrays where results of same id should merge in such a way that value of "type" should be key and value of "text" as value. Below is a sample of expected result:-
array:20 [
{
"id" => 1
"A" => "text1"
"B"=>"text2"
"C"=>"text3"
}
{
"id" => 2
"A" => "text4"
"B"=>"text5"
"C"=>"text6"
}
{
"id" => 3
"A" => "text7"
"B"=>"text8"
"C"=>"text9"
}...
]
I have tried using array_column.
$sortedRecords = array_column($data, 'text','type');
Using array_column, i am able to convert value of "type" as key and "text" value as its value. But i am not able getting how to display id also and how to loop for each distinct id as it is displaying result of only last id.
Following logic might help you on your way. The source array is called $arr, the result array $newArr.
The snippet runs through all unique id's in the source array and accumulates the accompanying text values.
$newArr = [];
$ids = array_values(array_unique(array_column($arr, 'id')));
foreach ($ids as $key => $id) {
foreach ($arr as $value) {
if ($value['id'] === $id) {
$newArr[$key]['id'] = $id;
$newArr[$key][$value['type']] = $value['text'];
}
}
}
working demo
You can get information in groups with group By and perform any operation you need
$records = Table::select('id','text','type')->groupBy('type')->paginate(20)->toArray();
I have the below array:
$myArray = [
[
"name" => null,
"price" => [
"height" => 0.0098974902792506,
"left" => 0.8385,
"page" => 1,
"top" => 0.51290208554259,
"width" => 0.0275,
],
],
[
"name" => null
"price" => [
"height" => 0.0098974902792506,
"left" => 0.838,
"page" => 1,
"top" => 0.56981265464829,
"width" => 0.028,
]
],
[
"name" => null
"price" => [
"height" => 0.010250972074938,
"left" => 0.5905,
"page" => 1,
"top" => 0.44114528101803,
"width" => 0.0285,
]
]
];
I am trying to check the array and get the name of the key that has a value (is not null) in each array. In the above example, this would be price.
However, the array could also look like this:
[
[
"name" => null,
"price" => [
"height" => 0.0098974902792506,
"left" => 0.8385,
"page" => 1,
"top" => 0.51290208554259,
"width" => 0.0275,
],
],
[
"name" => null
"price" => null
],
[
"name" => null
"price" => null
]
]
In this case, there is not an array key that has a value in all of the arrays.
Below is my attempt to achieve this:
$originalKeyWithValue = null;
foreach($myArray as $key => $item)
{
$originalKeyWithValue = array_key_first($item);
if (isset($myArray[$key+1])) {
$nextKeyWithValue = array_key_first($myArray[$key+1]);
if($originalKeyWithValue != $nextKeyWithValue){
$originalKeyWithValue = $nextKeyWithValue;
}
}
}
return $originalKeyWithValue;
However the code above returns name as the key, even though it is null in all of the arrays in $myArray.
This is what would I do:
// I take first element of array as a source for indexes
foreach ($myArray[0] as $index => $item) {
// next I extract all elements from all subarrays under current `$index`
$values = array_column($myArray, $index);
// then I filter values to remove nulls.
// This also removes 0, empty arrays, false,
// so maybe you should change filter process
$values_filtered = array_filter($values);
// if number of filtered items is same as in original array - no nulls found
if (count($values_filtered) === count($values)) {
echo $index;
// optionally
// break;
}
}
Although there is an accepted answer, I thought I would share a way to do this using Laravel collections.
$uniqueKeysWithValues = collect($myArray)->map(function($item){
return array_keys( collect($item)->filter()->toArray() ); //filter will remove all null
})->flatten()->unique();
This approach will give you all keys that has values in it, even if there are values in both keys.
I have an multidimensional array made out of form data that can look like this example:
array [
"absender" => "Maxim Ivan",
"email" => "maximivan#example.com",
"telefon" => "1234567890",
"fax" => null,
"grund" => "Gehaltserhöhung",
"termin" => [
0 => [
"person" => "Some Name",
"meeting" => "10.05"
],
1 => [
"person" => "Another Name",
"meeting" => "18.05"
],
2 => [
"person" => "Again another name",
"meeting" => null,
"next-possible-meeting" => "1"
],
3 => [
"person" => "And again",
"meeting" => null,
"next-possible-meeting" => "1"
],
4 => [
"meeting" => null,
],
"bemerkung" => "some notes by Maxim"
]
'person' and 'next-possible-meeting' are checkboxes while 'meeting' is a textarea. I only need the 'termin'-data when 'person' exists, so I store each of them in different arrays (one for persons, one for meetings and one for next-possible-meetings).
That means I don't need the array to be nested anymore, the 'termin' can (and should) be deleted out of it. But I don't know how to access the nested array correctly.
How do I delete the whole 'termin'-array out of the whole array and therefore make it a normal and not a multidimensional array?
Use unset()
if(isset($array['termin'])){
unset ($array['termin']);
}
Output:- https://3v4l.org/1Yj4F
Note:- isset() used to check that index exist or not, if not function call will saved.
