Function Problem after upgrade

[Hendy]

I have tried to upgrade my forum but I am getting the following error, is anyone able to help?

Parse error: syntax error, unexpected T_FUNCTION in /var/www/vhosts/crafttelly.com/httpdocs/forum/includes/functions.php on line 5313

Your php version is too old for the vbulletin version you are upgrading too.

Thank you Paul

I have installed the version for my php but now getting a database error:

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Access denied for user '‘crafttell'@'localhost' (using password: YES)
/var/www/vhosts/crafttelly.com/httpdocs/forum/includes/class_core.php on line 317

MySQL Error :

Is this easy to resolve, thank you.

Need to double check the details in your includes/config.php file are correct that that the database user still has full permissions to the database at your hosting.
