Problems connecting to mysql using phpMyAdmin

[Ali A Samii]

Well, from the browser, I got the following when I ran the phptest.php


( ! ) Warning: mysql_connect() [function.mysql-connect]: [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock) in /Volumes/External_Storage/www/phptest.php on line 2

0

and from the command line, the result was:

Alis-iMac:www ali$ php phptest.php

If so that doesn't work with mysqlnd (which is what php5-mysql now uses by default) so you should either (ideally) upgrade to the "new" algorithm or if you must keep the old algorithm, then install php5-mysql with the +mysql5 variant.
