Brian Swan's Blog: SQL Server Driver for PHP Connection Options: CharacterSet

Brian Swan has posted another in his series looking at connection options for the SQL Server driver for PHP. In his latest he looks at the "CharacterSet" setting, an easy way to define which encoding the remote database is using.

One thing that helped me understand the CharacterSet option was to realize that its name is a bit misleading (although it seems to be inline with other uses of CharacterSet or charset). It is used to specify the encoding of data that is being sent to the server, not the character set. With that in mind, the possible values for the option begin to make sense: SQLSRV_ENC_CHAR, SQLSRV_ENC_BINARY, and UTF-8.

He looks at each of these three options in more detail - SQLSRV_ENC_CHAR being the default, SQLSRV_ENC_BINARY when binary data is needed and UTF-8 when, obviously, you need UTF-8 data transfer between the client and server.
