Here’s the following code for connecting PHP to MySQL Database using PDO

<?php
$servername = "servername ";
$user = "user";
$password = "password";

try {
//setup database connection
$dbConn = new PDO("mysql:host=$servername ;dbname=test", $user, $password);
// set the PDO error mode to exception
$dbConn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
//display message if connected successfully
echo "Connected successfully";
}
catch(PDOException $e)
{
//display message if connection failed
echo "Connection failed: " . $e->getMessage();
}
?>

Important reminders! You need to close the connection using this code:
	
$dbConn = null;

This is the code above when put this into real action.

<?php
$servername = "localhost";
$user = "user";
$password = "";

try {
//setup database connection
$dbConn = new PDO("mysql:host=".$servername.";dbname=test", $user, $password);
// set the PDO error mode to exception
$dbConn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
//display message if connected successfully
echo "Connected successfully";
}
catch(PDOException $e)
{
//display message if connection failed
echo "Connection failed: " . $e->getMessage();
}
?>
