Let\'s say I have this string which I want to put in a multidimensional array.

Edit : The number of subfolders in the string are dynamic .. from zero sub folders to

Answer 1

This can be solved recursively in another way by taking the items from the beginning of the array and when the last item is reached just return it.

function make_tree( $arr ){
   if( count($arr) === 1){
      return array_pop( $arr );
   }else{
      $result[ array_shift( $arr )] = make_tree( $arr ) ; 
   }
   return $result;
}

$string  = "Folder1/Folder2/Folder3/filename1\n";
$string .= "Folder1/Folder2/Folder3/filename2\n";
$string .= "Folder4/Folder2/Folder3/filename3\n";

$string = trim( $string );

$files_paths = explode( PHP_EOL, $string);

$result = [];

foreach ($files_paths as $key => $value) {
   $parted = explode( '/', $value );
   $tree = make_tree( $parted );
   $result = array_merge_recursive( $result, $tree );
   
}
var_dump( $result );
