Question

I am trying to do a search of a multidimensional array in order to append stuff to specific elements. I got a function that does a search and returns the specific part of that array, but I need the key so I can do $array[key] edits.

Function to get array

function arraySearch($array, $key, $value)
{
    $results = array();
    if (is_array($array))
    {
        if (isset($array[$key]) && $array[$key] == $value)
            $results[] = $array;
        foreach ($array as $subarray)
            $results = array_merge($results, arraySearch($subarray, $key, $value));
    }
    return $results;
}

I don’t really know how to edit this to get the key from the array.

Try to use references “&”

function arraySearch($array, $key, $value)
{
   $results = array();
   if (is_array($array))
   {
       if (isset($array[$key]) && $array[$key] == $value)
           $results[] = &$array;
       foreach ($array as $subarray)
           $results = array_merge($results, arraySearch($subarray, $key, $value));
   }
   return $results;
}

And then you will be able to handle each $results entry as if it was directly in $array.

$searchResult = arraySearch($myArray, 'test', 'val');
foreach ($searchResult as &$item) {
  $item['nb']++;
}
