I tried out the latest version (Nano-5.5) of Uniform Server and found that it would timeout while trying to connect to anything using MySQL other than phpMyAdmin in the admin panel. After much fiddling around I was able to pinpoint the problem down to PHP 5.3.1 after I switched it with PHP 5.3.0 from Nano-5.1 and found I could connect again. I've only tested on Windows 7 (I use the Professional x64 version) so I don't know if it happens on other OSs. This is the code that I used to test (works with 5.3.0, timeout on 5.3.1): <?php
error_reporting(0);
$connect = mysql_connect("localhost", "root", "root");
$connect;
echo "Connection was ";
if (!$connect) { echo "not"; } echo " successful.";
?>
