laravel with() method versus load() method

Question

I really tried to understand the difference between the with() method and the load() method, but couldn\'t really understand.

As I see it,

Answer 1

As @damiani said, Both accomplish the same end results—eager loading a related model onto the first. In fact, they both run exactly the same two queries. The key difference is that with() eager loads the related model up front, immediately after the initial query (all(), first(), or find(x), for example); when using load(), you run the initial query first, and then eager load the relation at some later point.

There is one more difference between With() & load(), you can put the conditions when using with() but you can't do the same in case of load()

For example:

ProductCategory::with('children')
        ->with(['products' => function ($q) use($SpecificID) {
            $q->whereHas('types', function($q) use($SpecificID) {
                $q->where('types.id', $SpecificID)
            });
        }])
        ->get();
