                )

        )

I need to get new array that will look like this

    $newArray = [7053, 4610, 4591, 1756];

I have tried a lot of solution from this question Is there a function to extract a 'column' from an array in PHP? But i have no luck, also i have tried to foreach all like this

    foreach($array as $row => $innerArray){
        foreach($innerArray as $innerRow => $value){
          print_r($value) . "<br/>";
        }
      }

But this way i got only display of results, also i have tried answers from this question Foreach for arrays inside of an array

After all that i didnt manage to get proper new array, can somebody help me pleae, because I am not so good at php. Thanks in advance

Also i have tried

foreach ($dataRecommend as $item) {
    $namearray[] = $item['recommendationProductDetails'];
}

foreach ($namearray as $item) {
    $productArray[] = $item['productId'];
}
print_r($productArray);

Also i made it like this

foreach ($array as $item) {
    $namearray[] = $item['recommendationProductDetails'];
}
for($i = 0, $l = 4; $i < $l; ++$i) {
    foreach ($namearray as $item) {
 $productArray[] = $item[$i]['productId'];
 }
  }

print_r($productArray);

But i dont see this is good :(

Create a new empty array. Then instead of displaying the results, add the results to that new array. — RST, May 27 '20 at 10:33
`foreach` through `$array[recommendationProductDetails]` and add the value of `productId` to a new array — brombeer, May 27 '20 at 10:34
_“I have tried a lot of solution from this question”_ - then _show us_ what you actually tried, instead of just going “no luck”. (And please provide example data as a `var_export` in cases like this, so that everyone can simply copy&paste it to get _working_ code right away.) — CBroe, May 27 '20 at 10:34
Why are you so stricted, i told you i have looked answers but I dont know how to implement those answers in my code :( — Miomir Dancevic, May 27 '20 at 10:41
@CBroe If you know simple answer maybe you can help me, because as i said I am not so good in PHP, if you want ot help me? — Miomir Dancevic, May 27 '20 at 10:42
You said you _tried_ something, so you should _show us_ what you actually tried - as [ask] explains. Just going “I tried a bunch of stuff, but it all did not work” is _not_ a proper way to ask here on this site to begin with. _“If you know simple answer”_ - the simple answer is in what you already found - `array_column`. — CBroe, May 27 '20 at 10:46

Is there a function to extract a 'column' from an array in PHP?

Yes, there is array_column(array $input, mixed $column_key [, mixed $index_key = NULL]) doc

So in your code: array_column($array['recommendationProductDetails'], 'productId');

Notice: Undefined index: recommendationProductDetails – Miomir Dancevic May 27 '20 at 10:39
@MiomirDancevic then your `$array` appears to be something different, than what you have shown us as example data above. – CBroe May 27 '20 at 10:47
This comes from $array = json_decode( $bodyRecommend, true); – Miomir Dancevic May 27 '20 at 10:50
It doesn’t matter where it comes from, what matters is what the structure actually is. And according to what you have shown in your question, this should work. If it doesn’t - then your data must be somehow different from what you have shown us. – CBroe May 27 '20 at 11:02
I have updated my question, and found stupid solution that work, can you please help me refactor – Miomir Dancevic May 27 '20 at 11:02

You can use foreach to iterate over every item in $array['recommendationProductDetails']. $newArray will hold the extracted values:

$newArray = array();
foreach ($array['recommendationProductDetails'] as $arrayItem) {
    array_push($newArray, $arrayItem['productId']);
}
print_r($newArray);

will output

Array
(
    [0] => 7053
    [1] => 4610
    [2] => 4591
    [3] => 1756
)
