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

[Added]
- Support for PHP 7.4 RC 1
- Support for Linux Ubuntu 19.04 and Debian 10
- Feature Request [#929](https://github.com/microsoft/msphpsql/issues/929) - new [Language option](https://github.com/microsoft/msphpsql/wiki/Features#language) - Pull Request [#930](https://github.com/microsoft/msphpsql/pull/930)
- [Data Classification Sensitivity Metadata Retrieval](https://github.com/microsoft/msphpsql/wiki/Features#data-classification-sensitivity-metadata), which requires [MS ODBC Driver 17.2+](https://docs.microsoft.com/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server) and [SQL Server 2019 release candidate](https://docs.microsoft.com/sql/sql-server/sql-server-ver15-release-notes?view=sqlallproducts-allversions#-release-candidate-rc)
[Removed]
- Dropped support for Ubuntu 18.10
[Fixed]
- Issue [#570](https://github.com/microsoft/msphpsql/issues/570) - Fixed fetching varbinary data using client buffer with sqlsrv
- Pull Request [#972](https://github.com/microsoft/msphpsql/pull/972) - Removed redundant calls to retrieve the number of columns or rows in the current query result set
- Pull Request [#978](https://github.com/microsoft/msphpsql/pull/978) - PDO_SQLSRV implementation of PDO::getColumnMeta now references cached metadata rather than making an ODBC call every time
- Pull Request [#979](https://github.com/microsoft/msphpsql/pull/979) - Added support for data classification sensitivity metadata retrieval
- Pull Request [#985](https://github.com/microsoft/msphpsql/pull/985) - Fixed memory issues with data classification data structures
- Issue [#432](https://github.com/microsoft/msphpsql/issues/432) - Having any invalid UTF-8 name in the connection string will no longer invoke misleading error messages
- Issue [#909](https://github.com/microsoft/msphpsql/issues/909) - Fixed potential exception with locale issues in macOS
- Pull Request [#992](https://github.com/microsoft/msphpsql/pull/992) - Produced the correct error when requesting Data Classification metadata with ODBC drivers prior to 17
- Pull Request [#1001](https://github.com/microsoft/msphpsql/pull/1001) - Fixed compilation issue with PHP 7.4 alpha
- Pull Request [#1004](https://github.com/microsoft/msphpsql/pull/1004) - Fixed another compilation issue with PHP 7.4 alpha
- Pull Request [#1008](https://github.com/microsoft/msphpsql/pull/1008) - Improved data caching when fetching datetime objects
- Pull Request [#1011](https://github.com/microsoft/msphpsql/pull/1011) - Fixed a potential buffer overflow when parsing for escaped braces in the connection string
- Pull Request [#1015](https://github.com/microsoft/msphpsql/pull/1015) - Fixed compilation issues and addressed various memory leaks detected by PHP 7.4 beta 1
[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/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-2017)
- 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
- [Always Encrypted limitations](https://docs.microsoft.com/en-us/sql/connect/php/using-always-encrypted-php-drivers?view=sql-server-2017#limitations-of-the-php-drivers-when-using-always-encrypted)
[Known Issues]
- Data Classification metadata retrieval is not compatible with ODBC Driver 17.4.1
- 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)
- With ColumnEncryption enabled, calling stored procedure with XML parameter does not work (Issue [#674](https://github.com/Microsoft/msphpsql/issues/674))
- In SUSE 15, Azure Active Directory connections may fail if PHP is installed from packages (Issue [#934](https://github.com/Microsoft/msphpsql/issues/934))
