We are pleased to announce the technical preview for SQLSRV and PDO_SQLSRV drivers that support PHP 7.3. Both drivers have been built with PHP 7.1+ and tested on all supported platforms (Windows, Ubuntu 16.04, 18.04, and 18.10, RedHat 7, Debian 8 and 9, Suse 12, and macOS 10.11, 10.12, 10.13 and 10.14).
Notable items about the 5.5.0-preview release,
Added
- Added support for PHP 7.3.0
- Added support for Linux Ubuntu 18.10 and mac OS Mojave
- Feature Request #415 - new options at connection and statement levels for both drivers for formatting decimal values in the fetched results
Fixed
- Pull Request #854 - Clear Azure Key Vault data after connection attributes are successfully set or when exception is thrown
- Pull Request #855 - Improved performance by saving meta data before fetching and skipping unnecessary conversions for numeric data
- Pull Request #865 - Corrected the way SQLPutData and SQLParamData are used when sending stream data to the server
- Pull Request #878 - Modified the config files to enable Spectre Mitigations for PHP 7.1 (see related Request #836)
- Pull Request #891 - Improved performance of Unicode conversions
- Pull Request #892 - Removed warning messages while compiling extensions
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+
- Only Windows Certificate Store and Azure Key Vault are supported. Custom Keystores are not yet supported
- Issue #716 - With Always Encrypted enabled, named parameters in subqueries are not supported
- Always Encrypted limitations
Known Issues
- Connection pooling on Linux or macOS is not recommended with unixODBC < 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
- With ColumnEncryption enabled, calling stored procedures with XML parameters does not work (Issue #674)
- With ColumnEncryption enabled, fetching varbinary(max), varchar(max) or nvarchar(max) may fail with ODBC Driver 17.3 CTP
