List of Laravel validation rules

There's a lot more than 4-5 validation rules. From the docs.

I don't know if anyone else will find this useful, but you can use reflection to figure out the validators:

$validatorClass = new ReflectionClass(Illuminate\Validation\Concerns\ValidatesAttributes::class);

collect($validatorClass->getMethods(ReflectionMethod::IS_PUBLIC))
  ->filter(function($method){
    return Illuminate\Support\Str::startsWith($method->name,'validate');
  })
  ->map(function($method){
    return str_replace('validate_', '', Illuminate\Support\Str::snake($method->name));
  })
  ->dd();
