Take variable outside foreach loop in Laravel

Question

I have a query which show information from two tables in foreach loop on my blade view. This is the controller

public function details( $id ){

    $details = Item::find($id)->report;

    return view('details', compact('details'));
}

On my view I have

@foreach($details as $itemDetails)
    ....
@endforeach

Is it possible to show before foreach single variable from this query like?

{{ $details->id }}

@foreach($details as $itemDetails)
    ....
@endforeach

I want to get the $id.

To get id outside loop because if I want it from the foreach loop I need to put foreach outside one div which then render multiple divs because of the loop... — VLS

if you just want the id of first element then you can try something like collect($details)->first()->id — Cerlin

Yes you can, try this:

$details[0]->id;

Try to understand the concept, every time you use model to get some data it returns an array of object like:

array(
    0 => stdClass Object,
    1 => stdClass Object,
    and so on
)

So to access the data we use foreach() loop or you can directly call the index as done above.

But if you are calling index directly then put a check for its existence using isset()

its always recommended not to use hard-coded indexing as if can break if index is not available

@CerlinBoss in your case in the comment above isn't it the same or I'm wrong?

Yes it is highly recommended, and I have mentioned it in my updated answer

This will show error if $details has no records. Try to check the existence of the array with that index then access, try empty() or isset() functions for that.

@VLS : On accessing the property id, yes but the method first() would never throw error instead it will return false if no item found. So a simple if condition would be better
