Problems with Arrays

I'm updating a todo list and there are two tables that are involved in updating any todo. The todos table and a steps table. I've already created the relationships. And to update a todo, I have an update function that looks like this

 public function update(TodoCreateRequest $request, Todo $todo)
    {
        $todo->update([
            'title' => $request->title,
            'description' => $request->description,
        ]);

        $arrSize = sizeof($request->step);

        for ($i=0; $i<=$arrSize; $i++) { 
            return "hello";
        }
        
    }

Here lies the problem. When i do this

dd($request->step);

i get this result

array:3 [▼
  0 => "Don't do anything stupid"
  1 => "Don't leave your isolation chamber"
  2 => "Don't go outside"
]

Also when i try to get the size of $request->step by doing this

sizeof($request->step);

it gives me

3

but when i run the update function it only returns

hello once

instead of returning hello more than once according to the condition in the for loop.

It's displaying hello once because your using return. The return ends the loop. Instead try echo 'hello';

That worked but that was just a test to see if i had a problem. But the main problem is when i do this

 public function update(TodoCreateRequest $request, Todo $todo)
    {
        $todo->update([
            'title' => $request->title,
            'description' => $request->description,
        ]);

        if ($request->step) {
            foreach ($request->step as $step) {
                $todo->steps()->update(['name' => $step]);
            }
        }
        
    }

instead of updating the steps with

  0 => "Don't do anything stupid"
  1 => "Don't leave your isolation chamber"
  2 => "Don't go outside"

i get this saved to my database

 0 => "Don't do anything stupid"
  1 => "Don't do anything stupid"
  2 => "Don't do anything stupid"
