PHP can be configured with DB-Library access for a "Sybase" server (which also works with Microsoft servers), or with the mssql extension, intended exclusively for Microsoft servers.

	$ ./configure --prefix=/usr/local/freetds
	$ make
	$ sudo make install

	$ cd php
	$ ./configure --with-sybase=/usr/local/freetds
	$ make
	$ sudo make install

Option 2 is to use the CT-Library API. Again here, we run into minor difficulties at build time. Applications linking with Sybase's OpenClient have to link in a handful of libraries and these libraries vary slightly from platform to platform. When creating FreeTDS™ it was decided that there would be only one library: libct. This saves a great deal of library naming conflicts that Sybase ran into (e.g. libtcl is used both by Sybase and the language TCL), however some applications like PHP assume that all the Sybase libraries will be present. So, some hand editing of the Makefile is necessary to remove these extra libs. Build FreeTDS™ just as you would for DB-Library in with DB-Library, above. Then configure PHP with CT-Library.

	$ cd php
	$ ./configure --with-sybase-ct=/usr/local/freetds

Now edit the Zend/Makefile looking for the libZend_la_LDFLAGS line and remove -lsybtcl -lintl -lcomn and -lcs, leaving the -lct. Then proceed to make and install PHP.

	$ make
	$ sudo make install

We hope an upcoming version of PHP will automatically detect the presence of FreeTDS™ and include only the -lct library.

The third and newest option is to use the FreeTDS™ ODBC driver with PHP. First build the iODBC or unixODBC driver manager and FreeTDS™ as detailed in Preparing ODBC. Then build PHP with support for ODBC.

	$ cd php
	$ ./configure --with-iodbc=/usr/local
	$ make
	$ sudo make install

Now everything should run. There is a sample PHP script in the FreeTDS™ samples directory called odbctest.php.
