SQL Server 2008 to SQL Server 2005 Error

I have been developing locally on a machine with SQL Server 2008. Everything works fine. My server on our web server is SQL 2005. I recreated the tables and loaded data into my itemtype and category tables. I now and getting errors of both Combo boxes The error is
"Parse Errorsyntax error, unexpected T_STRING, expecting T_OLD_FUNCTION, or T_FUNCTION or T_VAR or ‘}’ in c:\inetpub\vhosts\digitallks.com\httpdocs\HTML\back\codebase\combo_connector.php<\b> on line 11

You can look online at www.digitalks.com/back and see the error.

Thanks

I installed SQL Server 2008 and still get the error. I notice on my failing server I have PHP 4.4.7
On my good server I have PHP 5.2.17 is this my issue???

According to error message, script just can’t connect to mssql server
Double-check that provided server name and credentials are valid and custom php script can connect with them to the database.

Connector was created for php 5.x, and its functionality with 4.x not fully tested ( it may partially work, but most probably - will not )
