Access denied for user 'root'#'localhost' (using password: NO) - mysql

Question

i created a simple db connection in my php page and its working fine since its not showing any error while executing this
<?php
$link = mysql_connect('www.ccccccccccccc.co.uk', 'cccccccccc', 'accccc');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
/*echo 'Connected successfully';*/
echo "DB : <font color='green'>ACTIVE</font>";
mysql_close($link);
?>
The problem is the page is showing error Access denied for user 'root'#'localhost' (using password: NO) while executing
<?php
$q = mysql_query("SELECT slno, name, idno FROM $memlist") or die(mysql_error());
echo "<table><tr><th> NO</th><th> NAME</th>
<th> ID NO</th></tr>";
while($row = mysql_fetch_array($q)){
extract($row);
echo "<tr><td>$slno</td><td>$name</td>
<td>$idno</td></tr>";
}
echo"</table>";
?>
i am working on server directly not on local host

Answer 1

You don't appear to be connecting to the database in the second piece of code, so it's trying to connect with default settings (which obviously won't be correct due to security concerns).
As for the first block of code, you're closing the connection immediately after opening it, which is kind of pointless.
