I have two arrays.
The first one is about exchange-rate and the display in my console is like this :
{
"exchange_rate": [
{
"id": "978",
"start_dateTime": "2021-08-01 07:35:02",
"target_value": "1.00000",
"currency_value_euro": "0.84097",
"currency_value_dollar_us": "1.00000",
"id_currency": "1",
"currency": "Dollar am\u00e9ricain",
"currency_symbol": "$US"
},
{
"id": "980",
"start_dateTime": "2021-08-01 07:35:02",
"target_value": "1.00000",
"currency_value_euro": "1.17454",
"currency_value_dollar_us": "0.71600",
"id_currency": "2",
"currency": "Livre sterling",
"currency_symbol": "\u00a3"
}
]
}
These data came from the database and I can display it by choosing particular dates with jQuery.
The second array contains only id_currency which in my console is like this : Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5
On my website, I want to be able to display specific exchange rate by specific currency and dates.
And here my problem appears, I can't find the way to loop on the first array, and loop again inside, on the second array and compare both like if first array has id_currency 1 and second array has id_currency 1 then display the complete line from first array.
I've tried several things but nothing works, at last i've tried this :
foreach ($res as $row){
$idBDD = $row['id_currency'];
$symbolBDD = $row['currency_symbol'];
echo $idBDD;
echo $symbolBDD;
//var_dump($row);
/*foreach ($arr as $line){
$idCheckbox = $line;
echo $idCheckbox;
}
if ($idBDD == $idCheckbox){
echo 'fine';
}
*/
}
I'll be grateful for your help
You need to access the array with $res["exchange_rate"] and loop through it then.
<?php
$res = [
"exchange_rate" => [
[
"id" => "978",
"start_dateTime" => "2021-08-01 07:35:02",
"target_value" => "1.00000",
"currency_value_euro" => "0.84097",
"currency_value_dollar_us" => "1.00000",
"id_currency" => "1",
"currency" => "Dollar américain",
"currency_symbol" => "\$US"
],
[
"id" => "980",
"start_dateTime" => "2021-08-01 07:35:02",
"target_value" => "1.00000",
"currency_value_euro" => "1.17454",
"currency_value_dollar_us" => "0.71600",
"id_currency" => "2",
"currency" => "Livre sterling",
"currency_symbol" => "£"
]
]
];
$output = null;
foreach ($res["exchange_rate"] as $row) {
if (!isset($output)) {
$output = $row;
}
$output = array_intersect_assoc($output, $row);
}
var_dump($output);
I think you could do it like this, of course if you're inside the loop, you won't need to put indices.

I have an array with fields
[
"house" => "30|30|30",
"street" => "first|second|third",
...
]
I want to get array
[
[
"house" => "30",
"street" => "first",
...
],
[
"house" => "30",
"street" => "second",
...
],
[
"house" => "30",
"street" => "third",
...
]
]
I know how I can solve this using PHP and loop, but maybe this problem has more beautiful solution
use zip
$data = [
"house" => "30|30|30",
"street" => "first|second|third",
];
$house = collect(explode('|',$data['house']));
$street = collect(explode('|',$data['street']));
$out = $house->zip($street);
$out->toarray();
Here's something I managed to do with tinker.
$original = [
"house" => "30|30|30",
"street" => "first|second|third",
];
$new = []; // technically not needed. data_set will instantiate the variable if it doesn't exist.
foreach ($original as $field => $values) {
foreach (explode('|', $values) as $index => $value) {
data_set($new, "$index.$field", $value);
}
}
/* dump($new)
[
[
"house" => "30",
"street" => "first",
],
[
"house" => "30",
"street" => "second",
],
[
"house" => "30",
"street" => "third",
],
]
*/
I tried using collections, but the main problem is the original array's length is not equal to the resulting array's length, so map operations don't really work. I suppose you can still use each though.
$new = []; // Since $new is used inside a Closure, it must be declared.
collect([
"house" => "30|30|30",
"street" => "first|second|third",
...
])
->map(fn($i) => collect(explode('|', $i))
->each(function ($values, $field) use (&$new) {
$values->each(function ($value, $index) use ($field, &$new) {
data_set($new, "$index.$field", $value);
});
});
$array = ["house" => "30|30|30","street" => "first |second| third"];
foreach($array as $key=> $values){
$explodeval = explode('|',$values);
for($i=0; $i<count($explodeval); $i++){
$newarray[$i][$key]= $explodeval[$i];
}
}
output:

"Size"
],
"value": [
"Red",
"XS"

},
"din": "10190537",
"markets": [
{
"id": 11,
"name": "paytmmall",

You are using laravel's only() method which returns an associative array.
You wish to convert each key-value pair into a subarray containing two associative elements -- the original key will be the value of the name element
and the original value will be the value of the value element.
By passing the original array keys and array values into array_map(), you can iterate them both synchronously.
compact() is a perfect native function to create the desired associative subarrays from the iterated parameters.
Code: (Demo)
$variations = $varitionValue->only(['Color', 'Size']);
$dataObject = (object)[
// ... your other data
'variations' => array_map(
function($name, $value) {
return compact(['name', 'value']);
},
array_keys($variations),
$variations
),
// ...your other data
];
var_export($dataObject);
Output:
(object) array(
'variations' =>
array (
0 =>
array (
'name' => 'Color',
'value' => 'Red',
),
1 =>
array (
'name' => 'Size',
'value' => 'XS',
),
),
)

I have the following array:
$arr = [
"elem-1" => [ "title" => "1", "desc" = > "" ],
"elem-2" => [ "title" => "2", "desc" = > "" ],
"elem-3" => [ "title" => "3", "desc" = > "" ],
"elem-4" => [ "title" => "4", "desc" = > "" ],
]
First I need to change the value from [ "title" => "1", "desc" = > "" ] to 1 (title's value).
I did this using array_walk:
array_walk($arr, function(&$value, $key) {
$value = $value["title"];
});
This will replace my value correctly. Our current array now is:
$arr = [
"elem-1" => "1",
"elem-2" => "2",
"elem-3" => "3",
"elem-4" => "4",
]
Now, I need to transform each element of this array into its own subarray. I have no idea on how to do this without a for loop. This is the desired result:
$arr = [
[ "elem-1" => "1" ],
[ "elem-2" => "2" ],
[ "elem-3" => "3" ],
[ "elem-4" => "4" ],
]
You can change your array_walk callback to produce that array.
array_walk($arr, function(&$value, $key) {
$value = [$key => $value["title"]];
});
Run the transformed array through array_values if you need to get rid of the string keys.
$arr = array_values($arr);
To offer an alternative solution you could achieve all of this with array_map
<?php
$arr = [
"elem-1" => [ "title" => "1", "desc" => "" ],
"elem-2" => [ "title" => "2", "desc" => "" ],
"elem-3" => [ "title" => "3", "desc" => "" ],
"elem-4" => [ "title" => "4", "desc" => "" ],
];
function convertToArray($key,$elem){
return [$key => $elem['title']];
}
$arr = array_map("convertToArray", array_keys($arr), $arr);
echo '<pre>';
print_r($arr);
echo '</pre>';
?>
outputs
Array
(
[0] => Array
(
[elem-1] => 1
)
[1] => Array
(
[elem-2] => 2
)
[2] => Array
(
[elem-3] => 3
)
[3] => Array
(
[elem-4] => 4
)
)
It doesn't make much sense to use array_walk() and modify by reference because the final result needs to have completely new keys on both levels. In other words, the output structure is completely different from the input and there are no salvageable/mutable parts. Mopping up the modified array with array_values() only adds to the time complexity cost.
array_map() has to bear a cost to time complexity too because array_keys() must be passed in as an additional parameter.
If you want to use array_walk(), use use() to modify the result array. This will allow you to enjoy the lowest possible time complexity.
More concise than array_walk() and cleaner to read, I would probably use a classic foreach() in my own project.
Codes: (Demo)
$result = [];
array_walk(
$arr,
function($row, $key) use(&$result) {
$result[] = [$key => $row['title']];
}
);
Or:
$result = [];
foreach ($arr as $key => $row) {
$result[] = [$key => $row['title']];
}
var_export($result);
You need to use array_map like
$new_arr= array_map(function($key,$val){
return [$key => $val['title']];},array_keys($arr),$arr);
I have array inside array:
{
"0" => array("key" => "code", "id" => "4", "value" => "yes"),
"1" => array("key" => "parameter", "id" => "4", "value" => "0"),
"2" => array("key" => "code", "id" => "5", "value" => "no"),
etc...
}
This is what I want to do: I want to have one dimension array in which key would be "id" and value would be "value". However, I need to filter out entries whose key is "parameters". So, in this example, the final array should look like this:
{
"4" => "yes",
"5" => "no"
}
I just can't seem to figure out how to do this. Could you please help me a bit? I tried writing this foreach inside foreach but I just can't wrap my head around how to filter data.
foreach ($settings AS $key => $value) {
$id = null;
$value = null;
foreach ($value AS $key2 => $value2) {
// No idea how to filter out uneccesary entries and save the correct ones
}
$finalArray[$id] = $value;
}
This should do it :
$finalArray = array();
foreach ($settings as $setting) {
if ($setting['key'] != 'parameter') {
$finalArray[$setting['id']] = $setting['value'];
}
}
Assuming all your entries have keys 'key', 'id' and 'value'.
use array_column and array_filter like this, if you want to filter more keys add them to out_keys array :
<?php
$array = [
["key" => "code", "id" => "4", "value" => "yes"],
["key" => "parameter", "id" => "4", "value" => "0"],
["key" => "code", "id" => "5", "value" => "no"]
];
$out_keys = ['parameter'];
$result = array_column(array_filter($array, function($item) use($out_keys) {
return !in_array($item['key'], $out_keys);
}), 'value', 'id');
echo "<pre>";
print_r($result);
output:
Array
(
[4] => yes
[5] => no
)
Assuming $data is your starting array, the code below will output what you want in $result
$result = [];
foreach(array_filter($data, function($el){return $el['key']!='parameter';}) as $el){
$result[$el['id']] = $el['value'];
}
Live demo
I have an array that looks like this
"name" => array:3 [
1 => "Hello"
4 => "Test"
21 => "Test2"
]
"runkm" => array:3 [
1 => "100.00"
4 => "1000.00"
21 => "2000.00"
]
"active" => array:3 [
1 => "1"
4 => "0"
21 => "0"
]
Can i somehow combine the matching keys with a PHP function so that the array would look like this instead
1 => array:3 [
name => "Hello"
runkm => "100.00"
active => "1"
]
4 => array:3 [
name => "Test"
runkm => "1000.00"
active => "0"
]
21 => array:3 [
name => "Test2"
runkm => "2000.00"
active => "0"
]
EDIT: Thanks for all the answers guys. What i was really looking for was a PHP built in function for this, which i probably should have been more clear about.
$newArr=array();
foreach($array1 as $key => $value){
$newArr[$key]=>array(
'name' =>$value[$key];
'runkm' =>$array2[$key];
'active'=>$array3[$key];
);
}
this is how you make a new array and then print the $newArr and check you get what you want or not? Good Luck!
<?php
$resultarr = array();
for($i=0;$i<count($sourcearr['name']);$i++) {
$resultarr[] = array('name'=>$sourcearr['name'][$i], 'runkm'=>$sourcearr['runkm'][$i], 'active'=>$sourcearr['active'][$i]);
}
This works well. And also, doesn't use hard coded keys.
<?php
$arr = [
"name" => [
1 => "Hello",
4 => "Test",
21 => "Test2"
],
"runkm" => [
1 => "100.00",
4 => "1000.00",
21 => "2000.00"
],
"active" => [
1 => "1",
4 => "0",
21 => "0"
]
];
// Pass the array to this function
function extractData($arr){
$newarr = array();
foreach ($arr as $key => $value) {
foreach($value as $k => $v) {
if(!isset($newarr[$k]))
$newarr[$k] = array();
$newarr[$k][$key] = $v;
}
}
return $newarr;
}
print_r(extractData($arr));
?>
I'm not sure if there's a function that does that in PHP but maybe you can try this
$arr1 = array(
"name" => array(
1 => "hello",
4 => "test",
21 => "test2",
),
"runKm" => array(
1 => "100",
4 => "200",
21 => "300",
),
"active" => array(
1 => "1",
4 => "0",
21 => "0",
),
);
// declare another that will hold the new structure of the array
$nArr = array();
foreach($arr1 as $key => $val) {
foreach($val as $sub_key => $sub_val) {
$nArr[$sub_key][$key] = $sub_val;
}
}
what this does is simply loop thru each array and its values and assign it to another array which is the $nArr. I hope it helps.
