Application Architecture

Developing Applications to Support UA in PHP

Cereate database that could handle IDN and EAI

# CREATE TABLE IF NOT EXISTS accounts ( 
   `id` int(11) NOT NULL AUTO_INCREMENT,
   `username` varchar(50) NOT NULL,
   `password` varchar(255) NOT NULL,
   `email` varchar(100) NOT NULL,
   `activation_code` varchar(50) DEFAULT '',
   PRIMARY KEY (`id`)
 ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

modify the registration system to be able to accept EAI email address

modify register.html fronm

# <input type="email" name="email" placeholder="Email" id="email" required>

to

# <input type="text" name="email" placeholder="Email" id="email" required>

modifythe registration system to be able to validate EAI email address

modify register.php from

# if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) { 

      exit('Email is not valid!');
 
  }

to

# if (preg_match('/^[ก-๙a-zA-Z0-9_+&*-]+(?:\.[ก-๙a-zA-Z0-9_+&*-]+)*@(?:[ก-๙a-zA-Z0-9-]+\.)+[ก-๙a-zA-Z]{2,16}$/u', $_POST['email']) == 0) {
      exit('Email is not valid!');
 
 }

modify the registration system to be able to send EAI email with PHPMailer

modify PHPMailer/src/PHPMailer.php from

# case 'php': 
  default:
  return filter_var($address, FILTER_VALIDATE_EMAIL) !== false;

to

# case 'php': 
  default: 
  return (bool) preg_match("/^[ก-๙a-zA-Z0-9_+&*-]+(?:\.[ก-๙a-zA-Z0-9_+&*-]+)*@(?:[ก-๙a-zA-Z0-9-]+\.)+[ก-๙a-zA-Z]{2,16}$/u", $address);

The regular expression works for Thai email address only. For general email verification for any email addresses in any language, the following expression may be considered:

• something@something ^(.+)@(.+)$
