Hello to all, welcome to therichpost.com. In this post, I will tell you, How to connect mysql database using pdo? PDO means PHP Data Object. PDO is more secure and it is opps based.

Here is the example code for connect mysql database using pdo:

define(‘DB_SERVER’, ‘localhost’);
define(‘DB_USERNAME’, ‘root’);
define(‘DB_PASSWORD’, ‘root’);
define(‘DB_DATABASE’, ‘testdatabse’);

class Connection{

public static $PDO =null;

public static function getConnectionInstance()
{
$dbhost=DB_SERVER;
$dbuser=DB_USERNAME;
$dbpass=DB_PASSWORD;
$dbname=DB_DATABASE;

try{
$PDO = new PDO(“mysql:host=$dbhost;dbname=$dbname”,$dbuser,$dbpass);
$PDO->exec(“set names utf8”);
$PDO->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $PDO;
} catch(PDOException $e){
die($e->getMessage());
}
}
}
$DBH = Connection::getConnectionInstance();
