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.*

- Fixed the issue with driver loading order in macOS
- Fixed null returned when an empty string is set to an output parameter (issue #308).
- Fixed incorrectly binding of unicode parameter when emulate prepare is on and the encoding is set at the statement level (issue #92).
- Fixed binary column binding when emulate prepare is on (issue #140).
- Improved performance by implementing a cache to store column SQL types and display sizes (issue #189).
- Fixed issue with the unsupported attribute PDO::ATTR_PERSISTENT in connection (issue #65).

[Limitation]
- Limited support for inout / output params when using sql_variant type
[Known Issues]
- When pooling is enabled in Linux or MAC
- unixODBC 2.3.4 or prior (Linux and MAC) might not return proper diagnostics 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 (https://github.com/Microsoft/msphpsql/wiki/Connection-Pooling-on-Linux-and-Mac)
