@ -433,27 +433,10 @@ You should be able to connect to your SQL Server/Azure SQL Database.
The drivers are distributed as shared binary extensions for PHP. They are available in thread safe (*_ts.so) and-non thread safe (*_nts.so) versions. The source code for the drivers is also available, and you can choose whether to compile them as thread safe or non-thread safe versions. The thread safety configuration of your web server will determine which version you need.
## Sample Code
For samples, please see the sample folder. For setup instructions, see [here](https://docs.microsoft.com/en-us/azure/sql-database/sql-database-develop-php-simple).

## Limitations
- This release contains the PHP 7 port of the SQLSRV and PDO_SQLSRV drivers, and does not provide backwards compatibility with PHP 5.
- Binding output parameters using emulate prepare is not supported.
- Linux
- ODBC 3.52 is supported but not 3.8.
- Connection using named instances using '\' is not supported.
- Local encodings other than UTF-8 are not supported, and SQLSRV_ENC_CHAR only supports ASCII characters with ASCII code of 0 to 127.
## Known Issues
- User defined data types and SQL_VARIANT.
- Binary column binding with emulate prepare ([issue#140](https://github.com/Microsoft/msphpsql/issues/140) )
- Linux
- The following features are not supported with connection pooling:
- PDO is only supported with unixODBC 2.3.1.
- Unicode connection strings
- sqlsrv_server_info and sqlsrv_client_info return false
- In certain scenarios a generic error message maybe returned instead of a specific error when pooling is disabled
- When retrieving data from columns with a data type of XML, varchar(max), nvarchar(max), or varbinary(max) no data maybe returned or the data maybe truncated depending on the length of the data in the source table.
