        $users = DB::select('select * from `title` INNER JOIN `title_img` on `title`.title_no = `title_img`.title_no AND `title`.title_name = ?', [$data]);
        $ab = array();
        foreach ($users as $user) {
            $name = $user->img_folder;
            $nam = 'http://127.0.0.1/shaadi/public/data/'.$name;
            $ab[] = glob($name);
        }

Answer

You can change this to

    foreach ($users as $user) {
        $name = $user->img_folder;
        $nam = 'http://127.0.0.1/shaadi/public/data/'.$name;
        $ab[] = glob($name);
    }

this

foreach ($users as $user) {
    $name = $user->img_folder;
    $nam = public_path('data/' . $name . DIRECTORY_SEPARATOR . '*');//getting real path
    $ab[] = \Illuminate\Support\Facades\File::glob($nam);//Matching all files
}

But remember this will only get contents of a directory not recursively.

To get the URL path you have to str_replace the paths like

str_replace(public_path(), '', $path)

& also you should apply the asset function

asset(str_replace(public_path(), '', $path))

Now if you are returning $ab variable which contains all the paths in a multidimensional array then you can either loop through or create a recursive function to achieve this or you can do it when setting value in $ab like this

$ab[] = collect(\Illuminate\Support\Facades\File::glob($nam))->map(function ($path)//this will convert array to laravel collection
        {
            return asset(str_replace(public_path(), '', $path));//converts to url
        })->filter(function ($path)
        {
            return $path;//removes any empty value
        })->values()//converts to values
        ->toArray();//converts to to array

This is a modified sample code from my project which worked for me although I didn't tested for your purpose but it should work.
