Connecting database to both mysqli and mysql entension


You can use both mysql and mysqli extension for executing SQL queries. Here is a tutorial on how to connect both the extensions to a database.

Create a file named config.php where you will connect to the database. Put the following code in it:

$mysqli = new mysqli(“localhost“, “username“, “password“, “db“);
if ($mysqli->connect_errno) {
    echo “Failed to connect to MySQL: (” . $mysqli->connect_errno . “) ” . $mysqli->connect_error;
}
$bd = mysql_connect(“localhost“, “username“, “password“) or die(mysql_error());
mysql_select_db(“db“,$bd) or die(mysql_error());
?>

Replace the red highlighted text with the credentials of your database connection.
