I read too many questions and answers around but couldn't be sure.
I have 2 questions
1.I turned my db connection into a function and I am not sure if its
safe ?
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');
define('DB_NAME', 'demo');
function DB()
try
$pdo = new PDO('mysql:host='.DB_SERVER.';dbname='.DB_NAME.'', DB_USERNAME, DB_PASSWORD);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $pdo;
catch (PDOException $e)
return "Error!: " . $e->getMessage();
die();
2.is my query done right way ?
query:
try
$pdo = DB();
$stmt = $pdo->prepare("SELECT * FROM settings");
$stmt->execute();
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
$c = htmlspecialchars($row['site_url']);
$e = filterString($row['contact']);
unset($stmt);
catch (PDOException $e)
exit($e->getMessage());
Thanks for any help

Perhaps keep one connection, rather than opening multiple connections to the Database. You can look into a project PDOEasy that I created to make MVC easy with PDO or use the below static example.
class DB
private $_connection;
private static $_instance;
public static function getInstance()
if(self::$_instance) return self::$_instance;
self::$_instance = new self();
return self::$_instance;
private function __construct()
$this->_connection = new PDO('mysql:host='.DB_SERVER.';dbname='.DB_NAME.'', DB_USERNAME, DB_PASSWORD, array(
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false
));
public function getConnection() return $this->_connection;
Which can be used like so:
$stmt = DB::getInstance()
->getConnection()
->Prepare('SELECT * FROM settings');
$stmt->execute();
foreach($stmt->fetchAll() as $row)
// ...
Looks good but how to make functions work ? example fucntionfunction catplace($par) Global $pdo; $stmt = $pdo->prepare("SELECT * FROM categories WHERE place=:par ORDER BY created ASC"); $stmt->execute(array(':par'=>$par)); $b = $stmt->fetchAll(PDO::FETCH_ASSOC); return $b;
