Microsoft Drivers for PHP for SQL Server (PDO_SQLSRV)

The Microsoft Drivers for PHP for SQL Server are PHP extensions that allow for the reading and writing of SQL Server data from within PHP scripts. The SQLSRV extension provides a procedural interface while the PDO_SQLSRV extension implements PDO for accessing data in all editions of SQL Server 2012 and later (including Azure SQL DB). These drivers rely on the Microsoft ODBC Driver for SQL Server to handle the low-level communication with SQL Server.
*This package contains only the PDO_SQLSRV driver.*

Changes

Fixed
- Fixed access token identity leaking across pooled connections — connections with different tokens could share the same pool entry, causing identity cross-contamination and use-after-free ([PR #1592](https://github.com/microsoft/msphpsql/pull/1592))
- Fixed prepared statement silently failing on insert when triggers or SET NOCOUNT OFF produce extra result sets, causing implicit transaction rollback with MARS enabled ([PR #1590](https://github.com/microsoft/msphpsql/pull/1590))
- Fixed fatal error when re-executing a prepared statement that returns multiple result sets with different column layouts ([PR #1596](https://github.com/microsoft/msphpsql/pull/1596))
- Fixed sqlsrv_errors() returning null after a failed connection when ODBC provides no diagnostic records ([PR #1595](https://github.com/microsoft/msphpsql/pull/1595))
- Fixed binary stream becoming invalid when the originating statement goes out of scope ([PR #1598](https://github.com/microsoft/msphpsql/pull/1598))

Limitations
- No support for inout / output params when using sql_variant type
- No support for inout / output params when formatting decimal values
- In Linux and macOS, setlocale() only takes effect if it is invoked before the first connection. Attempting to set the locale after connecting will not work
- Always Encrypted requires [MS ODBC Driver 17+](https://docs.microsoft.com/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server)
- Only Windows Certificate Store and Azure Key Vault are supported. Custom Keystores are not yet supported
- Issue [#716](https://github.com/Microsoft/msphpsql/issues/716) - With Always Encrypted enabled, named parameters in subqueries are not supported
- Issue [#1050](https://github.com/microsoft/msphpsql/issues/1050) - With Always Encrypted enabled, insertion requires the column list for any tables with identity columns
- [Always Encrypted limitations](https://docs.microsoft.com/sql/connect/php/using-always-encrypted-php-drivers#limitations-of-the-php-drivers-when-using-always-encrypted)

Known Issues
- Connection pooling on Linux or macOS is not recommended with [unixODBC](http://www.unixodbc.org/) < 2.3.7
- When pooling is enabled in Linux or macOS
- unixODBC <= 2.3.4 (Linux and macOS) might not return proper diagnostic information, such as error messages, warnings and informative messages
- due to this unixODBC bug, fetch large data (such as xml, binary) as streams as a workaround. See the examples [here](https://github.com/Microsoft/msphpsql/wiki/Features#pooling)
