I have the following array stored in $data
Array
(
[name] => JimBob
[data] => Array
(
[0] => Array
(
[date] => 2013-15-5
[pole] => 2
[race] => 43
)
[1] => Array
(
[date] => 2013-15-6
[pole] => 15
[race] => 34
)
[2] => Array
(
[date] => 2013-15-7
[pole] => 9
[race] => 54
)
)
)
I need to create a new array which looks like this
Array
(
[name] => JimBob
[data] => Array
(
[0] => 2013-15-5,2
[1] => 2013-15-6,15
[2] => 2013-15-7,9
)
)
So far I have this array_map function
$arr2['data'] = array_map(function($date) {
return $date['date'];
}, $data['data']);
print_r($arr2);
Which outputs the below, how can I get the pole values added to these dates separated by comma?
Array
(
[data] => Array
(
[0] => 2013-15-5
[1] => 2013-15-6
[2] => 2013-15-7
)
)
Use concatenation.
$arr2['data'] = array_map(function($date) {
return $date['date'] . ',' . $date['pole'];
}, $data['data']);

How to Flatten a Multidimensional Array?
(31 answers)
Closed 7 months ago.
There are many references on S/O showing various methods to flatten a multidimensional recursive array (with more than two levels). I have been through dozens (and tried most) but I'm still running into an odd problem with every one I've tried. What I am getting as a result is:
Array
(
)
Array

Array
(

Array
(
[0] => 1000043
[1] => 1000045
[2] => 1000050
)

(
[0] => 1000030
[1] => 1000032
[2] => 1000058
[3] => 1000064
) ...
But what I'm expecting is a truly flattened single array:
Array
[0] => 1000043
[1] => 1000045
[2] => 1000050
[3] => 1000030
[4] => 1000032
[5] => 1000058
[6] => 1000064
)
The method I found on S/O is supposed to handle an "empty array" (which I assume is the problem) but I'm still getting the wrong output. Here is my code:
function array_flatten5(array $array)
{
$flat = array(); // initialize return array
$stack = array_values($array); // initialize stack
while($stack) // process stack until done
{
$value = array_shift($stack);
if (is_array($value)) // a value to further process
{
$stack = array_merge(array_values($value), $stack);
}
else // a value to take
{
$flat[] = $value;
}
}
return $flat;
}
Could someone point out what I missing here because I'm thinking it's something simple but at this point my eyes are crossed with the number of attempts I've made. Thank you for any help you can provide.
Here is the original array. It is 4-deep:
Array ( [0] => 1000043 [1] => 1000045 [2] => 1000050 ) Array ( [0] => 1000030 [1] => 1000032 [2] => 1000058 [3] => 1000064 ) Array ( [0] => 1000041 [1] => 1000059 [2] => 1000069 ) Array ( [0] => 1000021 [1] => 1000044 [2] => 1000049 [3] => 1000071 ) Array ( [0] => 1000009 [1] => 1000013 [2] => 1000015 [3] => 1000017 [4] => 1000053 ) Array ( [0] => 1000022 [1] => 1000034 [2] => 1000070 ) Array ( [0] => 1000038 [1] => 1000047 [2] => 1000055 [3] => 1000063 ) Array ( [0] => 1000019 [1] => 1000054 [2] => 1000060 [3] => 1000066 [4] => 1000068 ) Array ( [0] => 1000006 [1] => 1000014 [2] => 1000016 [3] => 1000072 ) Array ( [0] => 1000024 [1] => 1000025 [2] => 1000046 [3] => 1000061 [4] => 1000067 ) Array ( [0] => 1000028 [1] => 1000039 [2] => 1000048 ) Array ( [0] => 1000042 [1] => 1000057 ) Array ( [0] => 1000027 [1] => 1000033 [2] => 1000036 [3] => 1000037 ) Array ( [0] => 1000008 [1] => 1000010 [2] => 1000012 [3] => 1000018 ) Array ( [0] => 1000026 [1] => 1000062 [2] => 1000065 ) Array ( [0] => 1000020 [1] => 1000023 [2] => 1000031 [3] => 1000035 [4] => 1000040 ) Array ( [0] => 1000007 [1] => 1000011 [2] => 1000029 ) Array ( [0] => 1000051 [1] => 1000052 [2] => 1000056 ) Array ( [0] => 1000001 [1] => 1000002 [2] => 1000003 [3] => 1000004 [4] => 1000005 ) Array ( [0] => 1000073 )
And here is the outcome using the array_walk_recursive suggestion ...

You didn't prepare suitable array, but looking on this code you need probably just array_walk_recursive() function.
$array = [
[1, 2, 3, 4],
[[5, 6], [7, 8]],
[[[9], [10]], [11]]
];
$result = [];
array_walk_recursive($array, function ($tempV) use (&$result) {
$result[] = $tempV;
});
print_r($result);
Output:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
[8] => 9
[9] => 10
[10] => 11
)
I have this array of userids. I want to combine the child userid arrays into one array within the parent arrays.
[0] => Array
(
[0] => Array
(
[userid] => 1610
)
[1] => Array
(
[userid] => 1614
)
[2] => Array
(
[userid] => 1616
)
)
[1] => Array
(
[0] => Array
(
[userid] => 1610
)
[1] => Array
(
[userid] => 1614
)
[2] => Array
(
[userid] => 1616
)
[3] => Array
(
[userid] => 1618
)
)
My desired result would look like...
[0] => Array
(
[userids] => Array
(
[0] => 1610
[1] => 1614
[2] => 1616
)
)
[1] => Array
(
[userids] => Array
(
[0] => 1610
[1] => 1614
[2] => 1616
[3] => 1618
)
)
Loop the array and use array_column to flatten the subarrays.
foreach($arr as $sub){
$res[][key($sub[0]) . "s"] = array_column($sub, 'userid');
}
var_dump($res);

You help is more appreciated
Try with -
$newArr = array();
foreach($array as $value) {
if (in_array($value['packageCode'], $pkgcodes)) {
$temp['productType'] = $value['productType'];
$temp['totalPrice'] = $value['totalPrice'];
$temp['packageCode'] = $value['packageCode'];
$temp['productCategory'] = $value['products']['productCategory'];
$newArr[] = $temp;
}
}
var_dump($newArr);
i have big problem, because i don't know how get values from this array where value is be key into new array. This is my source array
Array
(
[0] => Array
(
[ID] => 250602
[NAME] => qwe
)
[1] => Array
(
[ID] => 250603
[NAME] => wer
)
[2] => Array
(
[ID] => 250629
[NAME] => sdf
)
[3] => Array
(
[ID] => 250629
[NAME] => xcv
)
[4] => Array
(
[ID] => 250629
[NAME] => fghfgh
)
[5] => Array
(
[ID] => 250601
[NAME] => pggd
)
[6] => Array
(
[ID] => 250601
[NAME] => dfgdfg
)
[7] => Array
(
[ID] => 250606
[NAME] => dfgdfg
)
)
When id is the same it will be created a new table that will look like for id = 250629
[NAME] => Array
(
[0] => sdf
[1] => xcv
[2] => fghfgh
)
How about foreach loop like this?
<?php
$final_array=array();
foreach($arrays as $sub_arr){ //it will traverse loop for all sub-arrays
$final_array[$sub_arr['ID']][]=$sub_arr['NAME'];
}
print_r($final_array); //you should see expected output.
?>
It will product below output for your given data:
Array
(
[250602] => Array
(
[0] => qwe
)
[250603] => Array
(
[0] => wer
)
[250629] => Array
(
[0] => sdf
[1] => xcv
[2] => fghfgh
)
[250601] => Array
(
[0] => pggd
[1] => dfgdfg
)
[250606] => Array
(
[0] => dfgdfg
)
)
Working Demo
Like this
$by_name = array();
foreach($your_array as $item)
$by_name[$item['ID']] []= $item['name'];
This makes use of php's lazy array initialization ([]= creates a new array implicitly).
If you get your array from mysql, you might also consider GROUP_CONCAT.
I need to merge a PHP array, this array has 2 arrays into it named "targetXX", I can have 2 or more. Each target have the same keys, for each key I have an array with 2 values a and b, a is always the same in both targets, but I need to merge both B values like this:
Array
(
[0] => Array
(
[target] => hitcount(stats.asdf1.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 1200
[1] => 1392282200
)
[1] => Array
(
[0] => 1400
[1] => 1392282260
)
[2] => Array
(
[0] => 600
[1] => 1392282320
)

(
[0] => 200
[1] => 1392282380
)
[4] => Array
(
[0] => 400
[1] => 1392282440
)
[5] => Array
(
[0] => 600
[1] => 1392282500

Use array_merge() to achieve this:
$newArray = array();
foreach ($myArray['target2'] as $key => $innerArr1) {
$newArray['target'][$key] = array_merge(
$myArray['target1'][$key], /* 0th and 1st index */
array($innerArr1[1]) /* 2nd index */
);
}
print_r($newArray);
Output:
Array
(
[target] => Array
(
[0] => Array
(
[0] => 333333
[1] => 13
[2] => 99
)
[1] => Array
(
[0] => 444444
[1] => 15
[2] => 98
)
[2] => Array
(
[0] => 555555
[1] => 17
[2] => 97
)
)
)
Demo
The built-in function array_merge may do the work for you. You need to merge each subarrays in fact, as the array_merge_recursive function doesn't handle indexes.
$newArray = array();
foreach ($myArray['target2'] as $key => $arr) {
$newArray['target'][$key] = array_merge($myArray['target1'][$key], $arr[1]);
}
Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
If you have more than 2 keys to merge, you can loop on the algorithm multiple times.
