I'm learning PHP MYSQL and trying to create a database.
I'm following this tutorial http://www.raywenderlich.com/2941/how-to-write-a-simple-phpmysql-web-service-for-an-ios-app
So far I'm testing to see if the server has access to MySQL. When I use the following code.
?php
class RedeemAPI {
private $db;
// Constructor - open DB connection
function __construct() {
$this->db = new mysqli('localhost', 'username', 'password', 'promos');
$this->db->autocommit(FALSE);
}
// Destructor - close DB connection
function __destruct() {
$this->db->close();
}
// Main method to redeem a code
function redeem() {
// Print all codes in database
$stmt = $this->db->prepare('SELECT id, code, unlock_code, uses_remaining FROM rw_promo_code');
$stmt->execute();
$stmt->bind_result($id, $code, $unlock_code, $uses_remaining);
while ($stmt->fetch()) {
echo "$code has $uses_remaining uses remaining!";
}
$stmt->close();
}
}
// This is the first thing that gets called when this page is loaded
// Creates a new instance of the RedeemAPI class and calls the redeem method
$api = new RedeemAPI;
$api->redeem();
?
I get the following error:
Warning: mysqli::mysqli() [mysqli.mysqli]: [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) in /Users/user/Sites/promos/index.php on line 8
Warning: mysqli::mysqli() [mysqli.mysqli]: (HY000/2002): No such file or directory in /Users/user/Sites/promos/index.php on line 8

Fatal error: Call to a member function execute() on a non-object in /Users/user/Sites/promos/index.php on line 21
Did I perhaps forget to enable something?
It might explain why I cannot connect via my IP address to sequel pro and only to 127.0.0.1?
