OK
this is my error :

Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) in /var/www/html/testmy.php on line 3

host, user, pass, port .... are corect.
mysqld is runing, I can conect to database via SSH
php has mysql support enabled - phpinfo()

sure ... line 3 is:

$conn=mysql_connect('localhost', 'root', '') or die ("die mf");

Don't you need to put the port in with the hostname? :

mysql_connect('hostname:port', 'username', 'password')

eg mysql_connect('www.develop.com:3306', 'root', '');

This may not be the case with localhost, can't really rememer....

[lush_pierre]

whoops - forgot to escape the smiley....

hostname : port

it's not about port port is unchanged (3306).

This script works on other servers, it's something about my server
