Ademas de usar esas funciones .. presta atención a:
Cita: To compile PHP to support M$SQL on LINUX:
-Download FreeTDS:
www.freetds.org
and compile as required. Make sure to compile with the correct version of the protocol (read the readme)
-Compile PHP with '--with-sybase=/usr/local/freetds' or wherever you put freetds.
PHP will now support both mssql_*** and sybase_*** from Linux.. enjoy!

Un saludo,
