If you want to mass update
$data = [
'salary' => $request->salary,
'phone' => $request->phone,
'age' => $request->age,
'startDate' => $request->date,
'office' => $request->office,
];
// or $data = $request->all();
User::where('your-condition')->update($data); // it returns updated record counts
Also check in User model:
protected $fillable = ['your columns'];
