I wish to create an authorization system in my iOS app. I have to ship a affirmation e mail when registering a consumer. I do not know PHP very properly, however I discovered a few examples for registering and logging customers with mysql (phpMyAdmin) database. Now in my code I can register or login consumer. Since I do not know a lot about PHP, I do not fairly perceive add the e-mail affirmation code to my present PHP code. I wish to add new PHP code to my present PHP recordsdata to despatched affirmation e mail and efficiently end register. My code:
My php code:
Constants:
<?php
outline('DB_USERNAME', 'DB_USERNAME');
outline('DB_PASSWORD', 'DB_PASSWORD');
outline('DB_HOST', 'DB_HOST');
outline('DB_NAME', 'DB_NAME');
outline('USER_CREATED', 0);
outline('USER_ALREADY_EXIST', 1);
outline('USER_NOT_CREATED', 2);
DbConnect:
<?php
class DbConnect
{
personal $conn;
perform __construct()
{
}
/**
* Establishing database connection
* @return database connection handler
*/
perform join()
{
require_once 'Constants.php';
// Connecting to mysql database
$this->conn = new mysqli(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);
// Examine for database connection error
if (mysqli_connect_errno()) {
echo "Failed to hook up with MySQL: " . mysqli_connect_error();
}
// returing connection useful resource
return $this->conn;
}
}
DbOperation:
<?php
class DbOperation
{
personal $conn;
perform __construct()
{
require_once dirname(__FILE__) . '/Constants.php';
require_once dirname(__FILE__) . '/DbConnect.php';
// opening db connection
$db = new DbConnect();
$this->conn = $db->join();
}
/*
* This methodology is added
* We're taking username and password
* after which verifying it from the database
* */
public perform userLogin($username, $move)
{
$password = md5($move);
$stmt = $this->conn->put together("SELECT id FROM customers WHERE username = ? AND password = ?");
$stmt->bind_param("ss", $username, $password);
$stmt->execute();
$stmt->store_result();
return $stmt->num_rows > 0;
}
/*
* After the profitable login we are going to name this methodology
* this methodology will return the consumer knowledge in an array
* */
public perform getUserByUsername($username)
{
$stmt = $this->conn->put together("SELECT id, username, e mail, telephone FROM customers WHERE username = ?");
$stmt->bind_param("s", $username);
$stmt->execute();
$stmt->bind_result($id, $uname, $e mail, $telephone);
$stmt->fetch();
$consumer = array();
$consumer['id'] = $id;
$consumer['username'] = $uname;

$consumer['phone'] = $telephone;
return $consumer;
}
