Sponsor hosting : namecheap.com

<?php

$host = 'localhost';
$user = 'user1';
$pass = 'pass1';
$db = 'db1';




$con = mysqli_connect($host, $user, $pass,$db);


if($con)
{

    print 'CONNECTED';

}
else
{
     print 'NOT CONNECTED';
}

?>

Answer 1

to debug and check what happened , use this :

else
{
     print 'NOT CONNECTED';
     echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

instead of :

else
{
     print 'NOT CONNECTED';
}
