I'm having trouble connecting to my MySQL database. I don't know what's wrong.

Ok can we see the code you are using?

<?php
// database information
$dbhost="localhost";
$dbuser="noah0504_xmb1";
$dbpass="791305";
$dbname="noah0504_users";

// disconnected timeout
$timeout = 60; // in seconds.. you can make it higher or lower.. i suggest keeping it at 1 minute

// this will tell apart the people on your site
$ip=getenv("REMOTE_ADDR");

//connect to database
mysql_connect($dbhost,$dbuser,$dbpass);

// remove old connections so that the number doesn't continue to rise like a counter
$strq = "DELETE FROM joined WHERE hl < now()";
$qry = mysql_db_query($dbname,$strq);
$strq = "SELECT count(*) FROM joined WHERE IP='$ip'";
$qry = mysql_db_query($$dbname,$strq);

while ( $r = @mysql_fetch_array($qry) ) {
$ppl = $r["count(*)"];
}

if ($cpt) {
// checks for reloads, etc..
$strq = "UPDATE joined SET hl=hl + $timeout WHERE ip='$ip'";
} else {
// confirmed user updated into database
$strq = "INSERT INTO joined (ip, hl) VALUES ('$ip', now()+ $timeout)";
}
$qry = mysql_db_query($dbname,$strq);

// display the number of connected people
$strq = "SELECT count(*) FROM joined";
$qry = mysql_db_query($dbname, $strq);

while ( $result = @mysql_fetch_array($qry) ) {
$ppl = $result["count(*)"];
}
?>

is this your error or because this forum puts a space in some words...
mysql_connect($dbhost,$db user,$dbpass);
$dbuser

can you tell us any error that appears during your "non-connection"?

Not sure. I'll look at it.

It's the forum.

try changing this...

//connect to database
mysql_connect($dbhost,$dbuser,$dbpass);

to this...

// connect to the mysql database server.
$link_id = mysql_connect ($dbhost, $dbuser, $dbpass);
// select the specific database name we want to access.
if (!mysql_select_db($dbname)) die(sql_error());

note : there is no space after $dbname in the last line.

I got it to work, thanks.
