We have released Microsoft Drivers for PHP for SQL Server, version 5.11.0. This production release of the SQLSRV and PDO_SQLSRV drivers has been built with PHP 8.0, 8.1, and 8.2 and tested on all supported platforms.


Notable items about this release since the previous production release include:



  • Support for PHP 8.2
  • Support for Ubuntu 22.04
  • Pull request #1382 - Support for ActiveDirectoryIntegrated authentication


  • Support for PHP 7.3
  • Support for Ubuntu 16.04, Alpine 3.11 and Alpine 3.12

  • Pull request #1374 - Fixed ActiveDirectoryMsi Authentication behavior when specified UID by laclefyoshi


  • 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
    • Issue #1050 - With Always Encrypted enabled, insertion requires the column list for any tables with identity columns
    • Always Encrypted limitations

Known Issues

  • This release requires ODBC Driver 17.4.2 or above. Otherwise, a warning about failing to set an attribute may be suppressed when using an older ODBC driver.
  • 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


Let us know how we are doing and how you use our drivers by taking our pulse survey.



  • On Linux and macOS run the commands below:




sudo pecl install sqlsrv
sudo pecl install pdo_sqlsrv




  • Windows DLLs for PHP 8.0 or above can be downloaded as a package from Microsoft, or from the PECL repository for SQLSRV or PDO_SQLSRV.
  • Direct downloads for released binaries can also be found at the Github release tag.
