Flip associative array and store new values in subarrays to prevent losing duplicated values
(3 answers)
Closed 1 year ago.
I'm trying to flip array but it missed value from the key with the same name.
What do I have to use, to add couple values to key which occur multiple times in array?
For example, for
[
"Input.txt" => "Randy",
"Code.py" => "Stan",
"Output.txt" => "Randy"
]
the groupByOwners function should return
[
"Randy" => ["Input.txt", "Output.txt"],
"Stan" => ["Code.py"]
]
The current code:
class FileOwners
{
static $files;
public static function groupByOwners($files)
{
$flip = array_flip($files);
print_r($flip);
}
}
$files = array
(
"Input.txt" => "Randy",
"Code.py" => "Stan",
"Output.txt" => "Randy"
);
My function return Array ( [Randy] => Output.txt [Stan] => Code.py ) NULL.
So value "Input.txt" is missing. It has to be the same key for both values, so how can I put "Input.txt" with "Output.txt" in array for key [Randy]?
You will have to loop it yourself and build a new array:
$files = array(
"Input.txt" => "Randy",
"Code.py" => "Stan",
"Output.txt" => "Randy"
);
$new_files = array();
foreach($files as $k=>$v)
{
$new_files[$v][] = $k;
}
print_r($new_files);
A somewhat quick and a little hacky solution:
php > $files = array
php > (
php ( "Input.txt" => "Randy",
php ( "Code.py" => "Stan",
php ( "Output.txt" => "Randy"
php ( );
php > var_dump(array_reduce(array_keys($files), function($p, $c) use (&$files) { $p[$files[$c]] = $p[$files[$c]] ?? []; $p[$files[$c]][] = $c; return $p; }, []));
array(2) {
["Randy"]=>
array(2) {
[0]=>
string(9) "Input.txt"
[1]=>
string(10) "Output.txt"
}
["Stan"]=>
array(1) {
[0]=>
string(7) "Code.py"
}
}
NB: The use of '??' requires PHP 7.0.
Just to pull the important part out of the one-liner and make it at least slightly more readable:
array_reduce(array_keys($files), function($p, $c) uses (&$files) {
$p[$files[$c]] = $p[$files[$c]] ?? [];
$p[$files[$c]][] = $c;
}, []);
You could just as easily use the if(isset(...)) logic to ensure the array element in $p exists.

What's the most straightforward way in PHP to create an associative array from two parallel indexed arrays?
(2 answers)
Turn indexed array to associative array [duplicate]
(2 answers)
Closed last month.
I have two array values:
$values = ["Phillip", "Phil"];
In my set() method, I want to return an array object that first has a defined name key and second nickname key, like:
array(2) {
"name" => "Phillip"
"nickname" => "Phil"
}
Is there a better way to do it? I am new at PHP, though.
function set(?array $values)
{
$items = [];
foreach ($values as &$item) {
$item['name'] = $items;
$item['nickname'] = $items;
}
}
Like this
<?php
$values = ["Phillip", "Phil"];
function set(array $values): array
{
return [ "name" => $values[0], "nickname" => $values[1] ];
}
var_dump(set($values));
Result
array(2) {
["name"]=>
string(7) "Phillip"
["nickname"]=>
string(4) "Phil"
}
I have two 2d arrays where related row data from one array needs to be merged to the other.
The first one has information about the stock status of that day -- this is stored in a different database.
The second array has the information of the products like name, description and so on.
I wish to merge or combine the second arrays data into the first array based on a specific, shared column of values (product_id).
So far I'm using two foreach loops to combine the two.
How can I improve my code?
Sample data (the common key is product_id):
$array_one = [
[
'product_id' => 1,
'product_stock' => '1.2',
'stock_date' => '2022-02-15'
],
[
'product_id' => 2,
'product_stock' => '5',
'stock_date' => '2022-02-15'
],
];
$array_two = [
[
'product_id' => 1,
'product_slug' => 'product_one',
'product_description' => 'this is the product one'
],
[
'product_id' => 2,
'product_slug' => 'product_two',
'product_description' => 'this is the product two'
],
[
'product_id' => 3,
'product_slug' => 'product_three',
'product_description' => 'this is the product three'
],
];
My code:
$new_array = [];
foreach ($array_one as $key => $value) {
$new_array[ $value['product_id'] ] = $value ;
}
foreach ($array_two as $key => $value) {
if ( isset( $new_array[ $value['product_id'] ] ) ) {
$new_array[ $value['product_id'] ]['product_slug'] = $value['product_slug'];
$new_array[ $value['product_id'] ]['product_description'] = $value['product_description'];
}
}
Result as expected :
array(2) {
[1]=>
array(5) {
["product_id"]=>
int(1)
["product_stock"]=>
string(3) "1.2"
["stock_date"]=>
string(10) "2022-02-15"
["product_slug"]=>
string(11) "product_one"
["product_description"]=>
string(23) "this is the product one"
}
[2]=>
array(5) {
["product_id"]=>
int(2)
["product_stock"]=>
string(1) "5"
["stock_date"]=>
string(10) "2022-02-15"
["product_slug"]=>
string(11) "product_two"
["product_description"]=>
string(23) "this is the product two"
}
}
Modify your second array first, so that it uses the product ID as key - that makes the look-up of the item corresponding to the product ID from the first array much easier.
$array_two = array_combine(array_column($array_two, 'product_id'), $array_two);
$new_array = [];
foreach($array_one as $product) {
$product['product_slug'] = $array_two[$product['product_id']]['product_slug'];
$product['product_description'] =
$array_two[$product['product_id']]['product_description'];
$new_array[$product['product_id']] = $product;
}
One option you can use the array_map function:
$n_arr = array_map(function ($row) use ($array_two){
foreach ($array_two as $item){
if($item['product_id'] == $row['product_id']){
return $item + $row;
}
}
return false;
},$array_one);
Because the second array can be safely assumed to contain all possible product_ids, you can convert its data into a lookup array -- an array with associative first level key so that related row data can be swiftly accessed.
Then you merely need to loop over the first array and merge the related second array row to the appropriate first array row. (Demo)
$lookup = array_column($array_two, null, 'product_id');
var_export(
array_map(
fn($row) => $row + $lookup[$row['product_id']],
$array_one
)
);
The same functional style technique above can be translated to two separate foreach() loops if you prefer language constructs for iteration.
I am looking to group an array into subarrays based on its keys.
Sample Array
Array
(
[0] => Array
(
[a_id] => 1
[a_name] => A1
[b_id] => 1
[b_name] => B1
[c_id] => 1
[c_name] => C1
)
[1] => Array
(
[a_id] => 1
[a_name] => A1
[b_id] => 1
[b_name] => B1
[c_id] => 2
[c_name] => C2
)
[2] => Array
(
[a_id] => 1
[a_name] => A1
[b_id] => 2
[b_name] => B2
[c_id] => 3
[c_name] => C3
)
[3] => Array
(
[a_id] => 2
[a_name] => A2
[b_id] => 3
[b_name] => B3
[c_id] => 4
[c_name] => C4
)
)
I need this sample array to be converted into a JSON array of the following format:
Expected Output
[{
"a_id": 1,
"a_name": "A1",
"b_list": [{
"b_id": 1,
"b_name": "B1",
"c_list": [{
"c_id": 1,
"c_name": "C1"
}, {
"c_id": 2,
"c_name": "C2"
}]
}, {
"b_id": 2,
"b_name": "B2",
"c_list": [{
"c_id": 3,
"c_name": "C3"
}]
}]
}, {
"a_id": 2,
"a_name": "A2",
"b_list": [{
"b_id": 3,
"b_name": "B3",
"c_list": [{
"c_id": 4,
"c_name": "C4"
}]
}]
}]
I was able to group by a key using the code below.
$array = array(
array("a_id" => "1","a_name" => "A1","b_id" => "1","b_name" => "B1","c_id" => "1","c_name" => "C1"),
array("a_id" => "1","a_name" => "A1","b_id" => "1","b_name" => "B1","c_id" => "2","c_name" => "C2"),
array("a_id" => "1","a_name" => "A1","b_id" => "2","b_name" => "B2","c_id" => "3","c_name" => "C3"),
array("a_id" => "2","a_name" => "A2","b_id" => "3","b_name" => "B3","c_id" => "4","c_name" => "C4")
);
$return = array();
foreach($array as $val) {
$return[$val["a_id"]][] = $val;
}
print_r($return);
But my actual scenario involves grouping into sub arrays didn't worked.
Looking forward to see if there is an optimized way or useful function to get into my expected JSON response.
Note: I am looking into a generalized use case here . For example : a_list as countries,b_list as states and c_list as cities.
Man that is very specific use case for arrays. Well here is your solution.
$array = <YOUR SAMPLE ARRAY>
$output = [];
/*
* Nesting array based on a_id, b_id
*/
foreach ($array as $item) {
$aid = $item['a_id'];
$bid = $item['b_id'];
$cid = $item['c_id'];
if(!isset($output[$aid])){
$output[$aid] = [
'a_id' => $item['a_id'],
'a_name' => $item['a_name'],
'b_list' => [
$bid => [
'b_id' => $item['b_id'],
'b_name' => $item['b_name'],
'c_list' => [
$cid = [
'c_id' => $item['c_id'],
'c_name' => $item['c_name']
]
]
]
]
];
} else if (!isset($output[$aid]['b_list'][$bid])){
$output[$aid]['b_list'][$bid] = [
'b_id' => $item['b_id'],
'b_name' => $item['b_name'],
'c_list' => [
$cid => [
'c_id' => $item['c_id'],
'c_name' => $item['c_name']
]
]
];
} else if(!isset($output[$aid]['b_list'][$bid]['c_list'][$cid])) {
$output[$aid]['b_list'][$bid]['c_list'][$cid] = [
'c_id' => $item['c_id'],
'c_name' => $item['c_name']
];
} else {
// Do/Dont overrider
}
}
/*
* Removing the associativity from the b_list and c_list
*/
function indexed($input){
$output = [];
foreach ($input as $key => $item) {
if(is_array($item)){
if($key == 'b_list' || $key == 'c_list'){
$output[$key] = indexed($item);
} else {
$output[] = indexed($item);
}
} else {
$output[$key] = $item;
}
}
return $output;
}
$indexed = indexed($output);
print_r(json_encode($indexed, 128));
Interesting requirement there.
Here is my generalized solution that is also extendable.
function transform($array, $group=[
['a_id','a_name','b_list'],
['b_id','b_name','c_list'],
['c_id','c_name'],
]){
foreach($array as $a){
$r = &$result;
foreach($group as $g){
$x = &$r[$a[$g[0]]];
$x[$g[0]] = $a[$g[0]];
$x[$g[1]] = $a[$g[1]];
if(isset($g[2])) $r = &$x[$g[2]]; else break;
}
}
return transformResult($result);
}
function transformResult($result){
foreach($result as &$a)
foreach($a as &$b)
if(is_array($b)) $b = transformResult($b);
return array_values($result);
}
To extend this solution, all you have to do is modify the $group parameter,
either directly in the function declaration or by passing an appropriate value as the 2nd parameter.
Usage example:
echo json_encode(transform($array), JSON_PRETTY_PRINT);
This will return the same output assuming the same $array input in your example.
Now here is the code that works best in the given situation. I have created a similar situation and then explained the solution in detail.
Situation
The Order Form is multipage depending on the number of days served based on the package selected. Details of each package are stored in the database with the following fields:
package_id (Unique Field)
package_name (Name of the Package, e.g. Package A)
servings_count (Total Servings in a Day)
days_served (Number of Days Served in a Month)
In order to carry forward the selection of meals for each day and serving of that day to store as an Order in the database, I required a Multidimensional Array of PHP that can be defined/populated dynamically.
Expected output is something like:
Array
(
[Day 1] => Array
(
[meal_id_1] => Unique ID //to be replaced with user selection
[meal_code_1] => Meal Name //to be replaced with user selection
[meal_type_1] => Meal //prefilled based on the selected package
[meal_id_2] => Not Available //to be replaced with user selection
[meal_code_2] => 2 //to be replaced with user selection
[meal_type_2] => Meal //prefilled based on the selected package
)
[Day 2] => Array
(
[meal_id_1] => Unique ID //to be replaced with user selection
[meal_code_1] => Meal Name //to be replaced with user selection
[meal_type_1] => Meal //prefilled based on the selected package
[meal_id_2] => Not Available //to be replaced with user selection
[meal_code_2] => 2 //to be replaced with user selection
[meal_type_2] => Meal //prefilled based on the selected package
)
This above array has been created 100% dynamically based on the explained structure and number of servings and days. Below is the code with some explanation.
First, we have to declare two PHP Arrays.
$total_meals_array = []; //Primary, Multidimension Array
$meals_selected_array = []; //Meals Details Array to be used as primary array's key value.
After doing this, run MySQL query to read packages from the database. Now based on the result, do the following:
$total_meals_array = []; //Primary, Multidimension Array
$meals_selected_array = []; //Meals Details Array to be used as primary array's key value.
if( $num_row_packages >= 1 ) {
while($row_packages = mysqli_fetch_array ($result_packages)) {
$package_id = $row_packages['package_id'];
$package_name = $row_packages['package_name'];
$servings_count = $row_packages['servings_count'];
$days_served = $row_packages['days_served'];
//this for loop is to repeat the code inside `$days_served` number of times. This will be defining our primary and main Multidimensional Array `$total_meals_array`.
for ($y = 1; $y <= $days_served; $y++) {
//once inside the code, now is the time to define/populate our secondary array that will be used as primary array's key value. `$i`, which is the meal count of each day, will be added to the key name to make it easier to read it later. This will be repeated `$meals_count` times.
for ($i = 1; $i <= $meals_count; $i++) {
$meals_selected_array["meal_id_" . $i] = "Unique ID";
$meals_selected_array["meal_code_" . $i] = "Meal Name";
$meals_selected_array["meal_type_" . $i] = "Meal";
}
//once our secondary array, which will be used as the primary array's key value, is ready, we will start defining/populating our Primary Multidimensional Array with Keys Named based on `$days_served`.
$total_meals_array["Day " . $y] = $meals_selected_array;
}
}
}
That's it! Our dynamic Multidimensional Array is ready and can be viewed by simply the below code:
print "<pre>";
print_r($total_meals_array);
print "</pre>";
Thank you everyone, specially #yarwest for being kind enough to answer my question.
Here is the code, you can use it for index from a_ to y_ deep. The innerest element is null, if you don't want it. Terminate the for loop before last element, then process last element seperately. You also can do some improvement on this code. Hope this helps.
<?php
$array = array(
array("a_id" => "1","a_name" => "A1","b_id" => "1","b_name" => "B1","c_id" => "1","c_name" => "C1"),
array("a_id" => "1","a_name" => "A1","b_id" => "1","b_name" => "B1","c_id" => "2","c_name" => "C2"),

array("a_id" => "2","a_name" => "A2","b_id" => "3","b_name" => "B3","c_id" => "4","c_name" => "C4")
);
$arrays = array_map(function($v){return array_chunk($v, 2, true);}, $array);
$result = [];
foreach($arrays as $value)
{
$ref = &$result;
$len = count($value);
$index = 0;
for(; $index < $len; $index++)
{
$arr = $value[$index];
$char = key($arr)[0];
$charAdd = chr(ord($char)+1);
$key = $arr[$char.'_id'].$arr[$char.'_name'];
$listKey = $charAdd.'_list';
foreach($arr as $k => $v)
{
$ref[$key][$k] = $v;
}
$ref = &$ref[$key][$listKey];
}
}
var_dump($result);

This is rather interesting. As far as I can tell, you are trying to transform a flat array into a multidimensional array, as well as transforming the keys into a multidimensional representation.
The top level difference seems to reside in the part before the underscore of the a_* keys.
Then, for each of these keys, every other *_ letters should induce it's own list.
This recursive function does the trick without hardcoding, will work with whatever number of levels, letters (or whatever else) and right identifiers.
It seems to return exactly the json you show in the sample ($array being the array as defined in your question)
$multidimension = multidimensionalify($array, ['a', 'b', 'c'], ['name']);
var_dump(json_encode($multidimension, JSON_PRETTY_PRINT));
function multidimensionalify(
array $input,
array $topLevelLetters,
array $rightHandIdentifiers,
$level = 0,
$parentId = null,
$uniqueString = 'id'
)
{
$thisDimension = [];
$thisLetter = $topLevelLetters[$level];
foreach ($input as $entry)
{
$thisId = $entry["{$thisLetter}_{$uniqueString}"];
$condition = true;
if ($parentId !== null)
{
$parentLetter = $topLevelLetters[$level - 1];
$condition = $entry["{$parentLetter}_{$uniqueString}"] === $parentId;
}
if (!isset($thisDimension[$thisId]) && $condition)
{
$thisObject = new stdClass;
$thisObject->{"{$thisLetter}_{$uniqueString}"} = $thisId;
foreach ($rightHandIdentifiers as $identifier)
{
$thisObject->{"{$thisLetter}_{$identifier}"} = $entry["{$thisLetter}_{$identifier}"];
}
if (isset($topLevelLetters[$level + 1])) {
$nextLetter = $topLevelLetters[$level + 1];
$thisObject->{"{$nextLetter}_list"} = multidimensionalify($input, $topLevelLetters, $rightHandIdentifiers, $level + 1, $thisId, $uniqueString);
}
$thisDimension[$thisId] = $thisObject;
}
}
return array_values($thisDimension);
}
Try this function just pass your array and key name for grouping and then convert to json.
public function _group_by($array, $key) {
$return = array();
foreach ($array as $val) {
$return[$val[$key]][] = $val;
}
return $return;
}

Turning multidimensional array into one-dimensional array [duplicate]
(11 answers)
Closed 4 years ago.
I need to flatten an array while making sure that there are no duplicate keys.
For instance let's say I have this:
$arr = array(
$foo = array(
'donuts' => array(
'name' => 'lionel ritchie',
'animal' => 'manatee',
)
)
);
I need a flattened array that looks like this:
$arr = array(
'donuts name' => 'lionel ritchie',
'donuts animal' => 'manatee',
);
It needs to work even if we have more than 1 parent keys.
I have the following code, but I am not sure I can work with this.
foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array1)) as $k=>$v){
$array1c[$k] = $v;
}
It's very simple to do, just make it like this:
$arr = array(
$foo = array(
'donuts' => array(
'name' => 'lionel ritchie',
'animal' => 'manatee',
)
)
);
// Will loop 'donuts' and other items that you can insert in the $foo array.
foreach($foo as $findex => $child) {
// Remove item 'donuts' from array, it will get the numeric key of current element by using array_search and array_keys
array_splice($foo, array_search($findex, array_keys($foo)), 1);
foreach($child as $index => $value) {
// Adds an array element for every child
$foo[$findex.' '.$index] = $value;
}
}
Result of var_dump($foo); will be:
array(2) {
["donuts name"]=>
string(14) "lionel ritchie"
["donuts animal"]=>
string(7) "manatee"
}
Just try :)

How to re-index the values of an array in PHP? [duplicate]
(3 answers)
Closed 2 years ago.
I have an array:
$array = array(1,2,3,4,5);
If I were to dump the contents of the array they would look like this:
array(5) {
[0] => int(1)
[1] => int(2)
[2] => int(3)
[3] => int(4)
[4] => int(5)
}
When I loop through and unset certain keys, the index gets all jacked up.
foreach($array as $i => $info)
{
if($info == 1 || $info == 2)
{
unset($array[$i]);
}
}
Subsequently, if I did another dump now it would look like:
array(3) {
[2] => int(3)
[3] => int(4)
[4] => int(5)
}
Is there a proper way to reset the array so it's elements are Zero based again ??
array(3) {
[0] => int(3)
[1] => int(4)
[2] => int(5)
}
Try this:
$array = array_values($array);
Using array_values()
Got another interesting method:
$array = array('a', 'b', 'c', 'd');
unset($array[2]);
$array = array_merge($array);
Now the $array keys are reset.
Use array_splice rather than unset:
$array = array(1,2,3,4,5);
foreach($array as $i => $info)
{
if($info == 1 || $info == 2)
{
array_splice($array, $i, 1);
}
}
print_r($array);
Working sample here.
Just an additive.
I know this is old, but I wanted to add a solution I don't see that I came up with myself. Found this question while on hunt of a different solution and just figured, "Well, while I'm here."
First of all, Neal's answer is good and great to use after you run your loop, however, I'd prefer do all work at once. Of course, in my specific case I had to do more work than this simple example here, but the method still applies. I saw where a couple others suggested foreach loops, however, this still leaves you with after work due to the nature of the beast. Normally I suggest simpler things like foreach, however, in this case, it's best to remember good old fashioned for loop logic. Simply use i! To maintain appropriate index, just subtract from i after each removal of an Array item.
Here's my simple, working example:
$array = array(1,2,3,4,5);
for ($i = 0; $i < count($array); $i++) {
if($array[$i] == 1 || $array[$i] == 2) {
array_splice($array, $i, 1);
$i--;
}
}
Will output:
array(3) {
[0]=> int(3)
[1]=> int(4)
[2]=> int(5)
}
This can have many simple implementations. For example, my exact case required holding of latest item in array based on multidimensional values. I'll show you what I mean:
$files = array(
array(
'name' => 'example.zip',
'size' => '100000000',
'type' => 'application/x-zip-compressed',
'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
'deleteUrl' => 'server/php/?file=example.zip',
'deleteType' => 'DELETE'
),
array(
'name' => 'example.zip',
'size' => '10726556',
'type' => 'application/x-zip-compressed',
'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
'deleteUrl' => 'server/php/?file=example.zip',
'deleteType' => 'DELETE'
),
array(
'name' => 'example.zip',
'size' => '110726556',
'type' => 'application/x-zip-compressed',
'deleteUrl' => 'server/php/?file=example.zip',
'deleteType' => 'DELETE'
),
array(
'name' => 'example2.zip',
'size' => '12356556',
'type' => 'application/x-zip-compressed',
'url' => '28188b90db990f5c5f75eb960a643b96/example2.zip',
'deleteUrl' => 'server/php/?file=example2.zip',
'deleteType' => 'DELETE'
)
);
for ($i = 0; $i < count($files); $i++) {
if ($i > 0) {
if (is_array($files[$i-1])) {
if (!key_exists('name', array_diff($files[$i], $files[$i-1]))) {
if (!key_exists('url', $files[$i]) && key_exists('url', $files[$i-1])) $files[$i]['url'] = $files[$i-1]['url'];
$i--;
array_splice($files, $i, 1);
}
}
}
}
Will output:
array(1) {
[0]=> array(6) {
["name"]=> string(11) "example.zip"
["size"]=> string(9) "110726556"
["type"]=> string(28) "application/x-zip-compressed"
["deleteUrl"]=> string(28) "server/php/?file=example.zip"
["deleteType"]=> string(6) "DELETE"
["url"]=> string(44) "28188b90db990f5c5f75eb960a643b96/example.zip"
}
[1]=> array(6) {
["name"]=> string(11) "example2.zip"
["size"]=> string(9) "12356556"
["type"]=> string(28) "application/x-zip-compressed"
["deleteUrl"]=> string(28) "server/php/?file=example2.zip"
["deleteType"]=> string(6) "DELETE"
["url"]=> string(45) "28188b90db990f5c5f75eb960a643b96/example2.zip"
}
}
As you see, I manipulate $i before the splice as I'm seeking to remove the previous, rather than the present item.
I use $arr = array_merge($arr); to rebase an array. Simple and straightforward.
100% working for me ! After unset elements in array you can use this for re-indexing the array
$result=array_combine(range(1, count($your_array)), array_values($your_array));
Late answer but, after PHP 5.3 could be so;
$array = array(1, 2, 3, 4, 5);
$array = array_values(array_filter($array, function($v) {
return !($v == 1 || $v == 2);
}));
print_r($array);
Or you can make your own function that passes the array by reference.
function array_unset($unsets, &$array) {
foreach ($array as $key => $value) {
foreach ($unsets as $unset) {
if ($value == $unset) {
unset($array[$key]);
break;
}
}
}
$array = array_values($array);
}
So then all you have to do is...
$unsets = array(1,2);
array_unset($unsets, $array);
... and now your $array is without the values you placed in $unsets and the keys are reset
In my situation, I needed to retain unique keys with the array values, so I just used a second array:
$arr1 = array("alpha"=>"bravo","charlie"=>"delta","echo"=>"foxtrot");
unset($arr1);
$arr2 = array();
foreach($arr1 as $key=>$value) $arr2[$key] = $value;
$arr1 = $arr2
unset($arr2);
