I have been trying to get this to work correctly and I think I have finally come up with the correct solution because when I login on my iphone it seems to work fine. I am sort of new to php so I was wondering if I made any mistakes or if I could improve upon this.
I was working off of this example http://www.raywenderlich.com/2941/how-to-write-a-simple-phpmysql-web-service-for-an-ios-app for writing a web service.
All this is trying to do is return 403 if the username and password that I type in is valid.

header($status_header);
header('Content-type: ' . $content_type);
echo $body;
}

private $db;

function __construct() {
$this->db = new mysqli('127.0.0.1', 'username', 'password', 'promos');
$this->db->autocommit(FALSE);
}

function __destruct() {
$this->db->close();
}

if (isset($_POST["AccountEntry"]) && isset($_POST["PasswordEntry"])) {
// Put parameters into local variables
$AccountEntry = $_POST["AccountEntry"];
$PasswordEntry = $_POST["PasswordEntry"];
$user_id = 0;
$stmt = $this->db->prepare("SELECT username, password FROM usernames WHERE username=? AND password=?");
$stmt->bind_param("ss", $AccountEntry, $PasswordEntry);
$stmt->execute();
$stmt->bind_result($user, $pass);

break;

EDIT: Sorry I wasn’t more clear I mainly wanted to make sure that this piece of code is valid, and if I am checking the username/password correctly.
if (isset($_POST["AccountEntry"]) && isset($_POST["PasswordEntry"])) {
// Put parameters into local variables
$AccountEntry = $_POST["AccountEntry"];
$PasswordEntry = $_POST["PasswordEntry"];
$user_id = 0;
$stmt = $this->db->prepare("SELECT username, password FROM usernames WHERE username=? AND password=?");
$stmt->bind_param("ss", $AccountEntry, $PasswordEntry);
$stmt->execute();
$stmt->bind_result($user, $pass);
while ($stmt->fetch()) {
break;
}
$stmt->close();
if ($AccountEntry === $user && $PasswordEntry == $pass ) {
sendResponse(403, 'YESSIRRRRR');
return true;
First, why would you want to send “Not Found” if the username and password are correct? Anyway, thats what I did. This is completely different code but it does what you asked.
EDIT: Fixed $code and $status.
EDIT 2: Or you could just use Gabriel’s answer if you need to have the code that way.
