[SOLVED] error message being produced in my login

[ghqwerty]

when i go to my login page i get this error

 

Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'mysql4.000webhost.com' (4) in /home/a2350935/public_html/conn.php on line 10

 

however i havent changed it for ages and it has been working fine up to now.

 

this is line 10

    $dblink = mysql_connect ("$servername","$dbuser","$dbpassword")or die('CONNECTION ERROR: Could not connect to MySQL');

 

and this is the whole code

 

<?php
//conn.php
$servername='mysql4.000webhost.com';
$dbusername='why should i say ?';
$dbpassword='not telling you !';
$dbname='stop being so nosy!';

function connecttodb($servername,$dbname,$dbuser,$dbpassword){
    global $dblink;
    $dblink = mysql_connect ("$servername","$dbuser","$dbpassword")or die('CONNECTION ERROR: Could not connect to MySQL');
    mysql_select_db("$dbname",$dblink) or die ('Could not open database'.mysql_error());
}

connecttodb($servername,$dbname,$dbusername,$dbpassword);

?>

$dbuser and $dbusername

 

when you call the function are you using the right variable name?

It appears that 000webhosts SQL servers are down, no connection to any of them at the moment.
