Code used

    die("Database connection failed" . mysql_error());
}
?>

Answer 1

just change from

$connection = mysql_connect("localhost","root","");

to

$connection = mysqli_connect("localhost","root","");

notice the 'i' in mysqli

Answer 2

If you happen to use PHP 7 , then it is time to learn something new, as mysql_* functions have been deprecated since a while, and are now removed from PHP 7 as seen in this RFC.

If you are unsure about which version you are using, you can call phpinfo(); and this will show your current PHP version.

Alternatives:

• MySQLi Prepared Statements
• PDO

Answer 3

Try this code

<?php  

   $database = mysql_connect("hostname","username","password");
   mysql_select_db("databasename",$database);

?>
