PHP Create multidimensional array if subfolder = parent folder

Question

I'm trying to create a array that look like this to create a file explorer experience in one of my apps.

(
    [0] => Array
        (
            [FolderID] => 1
            [FolderName] => folder 1
            [ParentFolder] => 
            [SubFolder] => Array
                (
                    [0] => Array
                        (
                            [FolderID] => 2
                            [FolderName] => folder 2
                            [SubFolder] => Array
                                (
                                    [0] => Array
                                        (
                                            [FolderID] => 4
                                            [FolderName] => folder 4
                                            [ParentFolder] => 2
                                        )

                                )
                        )

                    [1] => Array
                        (
                            [FolderID] => 3
                            [FolderName] => folder 3
                            [SubFolder] => Array
                                (
                                    [0] => Array
                                        (
                                            [FolderID] => 5
                                            [FolderName] => folder 5
                                            [ParentFolder] => 3
                                            [SubFolder] => Array
                                                (
                                                    [0] => Array
                                                        (
                                                            (
                                                                [FolderID] => 7
                                                                [FolderName] => folder 7
                                                                [ParentFolder] => 5
                                                            )
                                                        )
                                                )
                                        )
                                )
                        )

                )
        )

    [1] => Array
        (
            [FolderID] => 6
            [FolderName] => folder 6
            [ParentFolder] => 
        )

)

The array I get from my SQL look this

(
    [0] => Array
        (
            [FolderID] => 1
            [FolderName] => folder 1
            [ParentFolder] => 
        )

    [1] => Array
        (
            [FolderID] => 2
            [FolderName] => folder 2
            [ParentFolder] => 1
        )

    [2] => Array
        (
            [FolderID] => 3
            [FolderName] => folder 3
            [ParentFolder] => 1
        )

    [3] => Array
        (
            [FolderID] => 4
            [FolderName] => folder 4
            [ParentFolder] => 2
        )

    [4] => Array
        (
            [FolderID] => 5
            [FolderName] => folder 5
            [ParentFolder] => 3
        )

    [5] => Array
        (
            [FolderID] => 6
            [FolderName] => folder 6
            [ParentFolder] => 
        )

    [6] => Array
        (
            [FolderID] => 7
            [FolderName] => folder 7
            [ParentFolder] => 5
        )

)

I've been racking my brains for some time over this problem.

What I want to achieve is a browser like experiance that look like this https://bootsnipp.com/snippets/REyGB

|Folder 1
|  |___ Folder 2
|  |  |___ Folder 4
|  |___ Folder 3
|     |___ Folder 5
|        |___ Folder 7
|Folder 6

What is the loop (for or while) that I should be using? I'm kidding lost on how to do this.

Some code example will be appreciated. I'm also open to any suggestion if there's any better way or simpler way of doing this!
