Storing DirectoryIterator in array (folders and files)

Question

I have this foreach for retrieving subdirectories and files and then storing them in an array, I'm using RecursiveDirectoryIterator but I'm open to use any other that can solve my issue:

$it = new RecursiveDirectoryIterator($path);

foreach(new RecursiveIteratorIterator($it) as $file){
    if ($file->getExtension() == 'jpg'){

        $folder = ltrim($file->getPath(), $path."/");
        $images[] = array("cod" => $folder, "images" => $file->getFilename());

    }
}

And the output is:

array(294) {
  [0]=>
  array(2) {
    ["cod"]=>
    string(5) "8322C"
    ["images"]=>
    string(36) "8322c-pastillas-del-sedona0-12-2.jpg"
  }
  [1]=>
  array(2) {
    ["cod"]=>
    string(5) "8322C"
    ["images"]=>
    string(36) "8322c-pastillas-del-sedona0-12-1.jpg"
  }
  [2]=>
  array(2) {
    ["cod"]=>
    string(5) "7877C"
    ["images"]=>
    string(29) "7877c-pastillas-4runner-2.jpg"
  }
  [3]=>
  array(2) {
    ["cod"]=>
    string(5) "7877C"
    ["images"]=>
    string(29) "7877c-pastillas-4runner-1.jpg"
  }
  [4]=>
  array(2) {
    ["cod"]=>
    string(9) "D889-7767"
    ["images"]=>
    string(30) "pastilla-spectra-rio-bex-1.jpg"
  }
  ...

So what I want to achieve is to not repeat the variable cod (which in this case is the directory), so it looks like:

array(294) {
  [0]=>
  array(2) {
    ["cod"]=>
    string(5) "8322C"
    ["images"]=>
    string(74) "8322c-pastillas-del-sedona0-12-1.jpg, 8322c-pastillas-del-sedona0-12-2.jpg"
  }
  [1]=>
  array(2) {
    ["cod"]=>
    string(5) "7877C"
    ["images"]=>
    string(60) "7877c-pastillas-4runner-1.jpg, 7877c-pastillas-4runner-2.jpg"
  }
  [3]=>
  array(2) {
    ["cod"]=>
    string(9) "D889-7767"
    ["images"]=>
    string(30) "pastilla-spectra-rio-bex-1.jpg"
  }
  ...

Can you help me please? Is that possible?

You can first check if the element is repeated, and add it to array if it's not, else add the new one in existing entry:

$index = findArrayInArray($images, "cod", $folder);
if($index >= 0)
    $images[$index]["images"] .= ", ".$file->getFilename());
else
    $images[] = array("cod" => $folder, "images" => $file->getFilename());

instead of

$images[] = array("cod" => $folder, "images" => $file->getFilename());

Using a simple function which searches for an array inside array (using a key and value):

function findObjectInArray($arr, $key, $val){
    for($i = 0; $i < count($arr); $i++)
        if (isset($arr[$i][$key]) and $arr[$i][$key] == $val)
            return $arr[$i];
        return -1;
}

Hello, thank you for your reply, I fixed some typos in your code (an extra ")" and the name of the function), but is throwing this error: _Illegal offset type_ in this line: `$images[$index][$images] .= ", ".$file->getFilename();` – Luis Apr 04 '20 at 20:13
Oh, I'm sorry that was supposed to be string. I edited that line. Please try to edit my answer with those typos you fixed. Thanks in advance. – Kamyar Mirzavaziri Apr 04 '20 at 23:38
Maybe you didn't remove the wrong `$`, this should work. – Kamyar Mirzavaziri Apr 05 '20 at 05:12
Yes I did like this: `$images[$index]["images"] .= ", ".$file->getFilename();` – Luis Apr 06 '20 at 15:21
Thank you for your effort anyway! I found the solution here: https://stackoverflow.com/questions/51507724/combining-duplicate-keys-in-a-multidimensional-array-in-php – Luis Apr 06 '20 at 21:30
