Title Body

Today, I removed and reinstalled the latest version of lampp in order to move to php 5.30, and suddenly a very simple app is failing to connect to the mysql database. I'm using PDO to connect, and receiving the following error: Warning: PDO::__construct() [pdo.--construct]: [2002] Invalid argument (trying to connect via unix://) in /home/raistlin/www/todoapp/home.php on line 9 Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2002] Invalid argument' in /home/raistlin/www/todoapp/home.php:9 Stack trace: #0 /home/raistlin/www/todoapp/home.php(9): PDO->__construct('mysql:host=loca...', 'USER', 'PASSWORD') #1 {main} thrown in /home/raistlin/www/todoapp/home.php on line 9 I am not catching the error at the moment, for the sake of debugging it. The following code is enough to replicate the issue on my system: <?php $DBACCESS = array( "connstring"=>"mysql:host=localhost;dbname=todoapp", "host"=>"localhost", "user"=>"user", "password"=>"password", "todoapp"=>"todoapp" ); echo implode('<br \>',$DBACCESS); $dbh = new PDO($DBACCESS['connstring'],$DBACCESS['user'],$DBACCESS['password']); $dbh = null; ?> Looking online, I've found one or two other people with the same issue, but none of them have received a response, much less a working one. Does anyone know what is happening? Is there something I missed in the configuration? What do I need to do to fix it?
