如何使用其他功能检查电子邮件的格式是否正确([符号数] @ [符号数]。[符号数])以及使用其添加时是否唯一insertUser? (所有信息都从.txt文件中读取)。
代码:
class User{
function randomPassword($length = 8){
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$randomString = '';
for ($i = 0; $i < $length; $i++) {
$randomString .= $characters[rand(0, strlen($characters) - 1)];
}
return $randomString;
}
function insertUser($firstName, $lastName, $email){
global $DB;
$DB->query("INSERT INTO `users` (`fname`, `lname`, `password` , `email`) values ('$firstName', '$lastName', '" . randomPassword() . "', '$email') ");
}
在索引文件中:
$USER = new User();
$data = readData();
foreach($data as $nr => $user){
$USER->insertUser($user['first_name'], $user['last_name'], $user['email']);
}

请致电$this->randomPassword();
电子邮件验证
function checkEmail($email) {
if(preg_match("/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])
?*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/",$email)){
list($username,$domain)=split('@',$email);
if(!checkdnsrr($domain,'MX')) {
return false;
}
return true;
}
return false;
}

要插入随机字符串,您应该这样做:
将insertUser函数更改为:
function insertUser($firstName, $lastName, $email){
global $DB;
$DB->query("INSERT INTO `users` (`fname`, `lname`, `password` , `email`) values ('$firstName', '$lastName', '" . $this->randomPassword() . "', '$email') ");
}
