Convert Query to Eloquent

How to make that query with eloquent

SELECT employees.first_name, companies.name FROM employees
JOIN companies ON employees.company_id = companies.id

My relationships

public function employees()
{
    return $this->hasMany(Employee::class);
}

public function company()
{
    return $this->belongsTo(Company::class);
}

I fetching the name with a given ID, but how can I find it for all. Or maybe I am thinking wrong

$employee = $employee->all()->find($id)->company->name;

Answer

I assumed your employees Model name as Employee and companies Model name as Company

$employees = Employee::with('company')->get();

if(!empty($employees)){
    foreach($employees as $employee){
        echo $employee->first_name;
        echo $employee->company->name;
    }
}

If you want to search per id then you may do as below.

$employee = Employee::with('company')->find($id);
echo $employee->company->name;
