Question

In my blade file i have a html form for user in which input field email have type email. But i think it provide inconsistent email format validation. example it show abc#xyz and abc#xyz.com both are correct email address but in my controller, validator method return me invalid email format for abc#xyz. How can i resolve this issue???
In my blade file:
<input type="email" name="email" value="">
And in my controller:
$validator = Validator::make($request->all(), [
'email' => 'email|unique:table_name,col_name',
],[
'email.unique' => 'email is already in used',
]);
if ($validator->fails()) {
return redirect()->back()->withInput($request->all())->withErrors($validator);
}

Actually Laravel using PHP builtin function called filter_var (source code).
// Illuminate\Validation\Concerns\ValidateAttributes
/**
* Validate that an attribute is a valid e-mail address.
*
* #param string $attribute
* #param mixed $value
* #return bool
*/
public function validateEmail($attribute, $value)
{
return filter_var($value, FILTER_VALIDATE_EMAIL) !== false;
}
The rules implemented by PHP is quite different with the rules implemented by the browser. abc#xyz passed the browser validation rule because xyz is a valid hostname (you can read it here). But PHP implementing more strict rule that the email address should contains top level domain.
