It could be in if statement directly
@if ($shires->isNotEmpty() && $shire = $shires->first())
{{ $shire->name }}
@endif

How to define global variable in if with php?
I have code something like this:
@php
if ($shires){
$shire = $shires->first();
}
@endphp
@if ($shire)
{{ $shire->name }}
@endif
I see this error
Undefined variable: shire

Or even simpler :)
@if ($shires->isNotEmpty())
{{ $shires->first()->name }}
@endif
//or
{{ $shires->first()->name ?? '' }}

I get this error.
Call to a member function isNotEmpty() on null

Please show how you are getting $shires

If your plan was to use ->first() then you have to have a collection.

A quick fix is to default to a collection
$shires = null; //replace this
$shires = collect(); //with this

Instead of
$shires = null;
you can do
$shires = collect([]);
Or just
@if ($shires && $shire = $shires->first())
{{ $shire->name }}
@endif

What is collect([])?
Level 75
With that you create an empty collection.
Level 10
OK, Thank you.
Level 102
You dont need to add [] inside collect. It defaults to an empty array
