You will only need one ODBC driver, which might be one of those you list, or might come from another source such as those from my employer.
The ODBC driver must match bitness with your PHP binary (whether that's the standalone executable, mod_php
as used with Apache, or otherwise), and you'll generally be best off if you also have an ODBC driver manager (e.g., iODBC, unixODBC).
If you get pre-built binaries for any of these components, note that they must be compatible with the libc
in your environment, which may mean that you need to add a compatibility library (for instance, binaries built for libc 2.5
need a compatibility library to be used in a libc 2.12
environment).
