Database problem - works in Windows - not Linux

Hi there, I'm moving an application from Windows -> Linux, and am having a problem with the database. I have the following script to test my database connection (Linux): -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= $connection = mysql_connect("localhost","","") or die ("Couldn't connect."); $dbs = mysql_list_dbs($connection) or die("Couldn't list databases."); $db_list = "<ul>"; $i = 0; while ($i < mysql_num_rows($dbs)) { $db_names[$i] = mysql_tablename($dbs,$i); $db_list .= "<li>$db_names[$i]</li>"; $i++; } $db_list .= "</ul>"; -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= This works fine and displays: * mysql * sasdap * test * testDB However, the code that I developed under Windows doesn't work in Linux: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= function db_connect() { // the connection string (host, user, password) $result = mysql_pconnect("localhost", "", ""); if (!$result) return false; if (!mysql_select_db("sasdap")) return false; // false is returned! return $result; } -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Which is called like so: // connect to db $conn = db_connect(); if (!$conn) return 0; Any thoughts on why this is happening?
