Microsoft SQL Server Functions (PDO_SQLSRV)

Введение

PDO_SQLSRV is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to MS SQL Server (starting with SQL Server 2005) and SQL Azure databases.

Установка

The PDO_SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The PDO_SQLSRV download comes 8 driver files, four of which are for PDO support. If you are running non-thread-safe PHP (PHP 5.3), use the php_pdo_sqlsrv_53_nts.dll file. (You should use a non-thread-safe version if you are using IIS as your web server). If you are running thread-safe PHP, use the php_pdo_sqlsrv_53_ts.dll file. Similarly for PHP 5.4, use the php_pdo_sqlsrv_54_nts.dll or php_pdo_sqlsrv_54_ts.dll depending on whether your PHP installation is non-thread-safe or thread-safe.

The most recent version of the driver is available for download here: » SQLSRV 3.0 download. If you need support for PHP 5.2 and/or PHP compiled with VC6, use the 2.0 release of the driver: » SQLSRV 2.0 download.

For more information about system requirements, see » SQLSRV System Requirements.

The PDO_SQLSRV extension is only compatible with PHP running on Windows. For Linux, see ODBC and » Microsoft's SQL Server ODBC Driver for Linux.

Предопределенные константы

Перечисленные ниже константы определены данным драйвером и будут доступны только в случае, если PHP был собран с поддержкой этого расширения или данное расширение было подгружено динамически во время выполнения. Вдобавок, эти драйверо-зависимые константы должны быть использованы только совместно с этим драйвером. Использование атрибутов, специфичных для некоторого драйвера с другим драйвером может вызвать неожиданное поведение. Если ваш код выполняется с несколькими драйверами, то можно использовать функцию PDO::getAttribute() для получения атрибута PDO_ATTR_DRIVER_NAME для проверки драйвера.

PDO::SQLSRV_TXN_READ_UNCOMMITTED (integer)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Read Uncommitted.
PDO::SQLSRV_TXN_READ_COMMITTED (integer)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Read Committed.
PDO::SQLSRV_TXN_REPEATABLE_READ (integer)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Repeateable Read.
PDO::SQLSRV_TXN_SNAPSHOT (integer)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Snapshot.
PDO::SQLSRV_TXN_SERIALIZABLE (integer)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Serializable.
PDO::SQLSRV_ENCODING_BINARY (integer)
Specifies that data is sent/retrieved as a raw byte stream to/from the server without performing encoding or translation. This constant can be passed to PDOStatement::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ENCODING_SYSTEM (integer)
Specifies that data is sent/retrieved to/from the server as 8-bit characters as specified in the code page of the Windows locale that is set on the system. Any multi-byte characters or characters that do not map into this code page are substituted with a single byte question mark (?) character. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ENCODING_UTF8 (integer)
Specifies that data is sent/retrieved to/from the server in UTF-8 encoding. This is the default encoding. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ENCODING_DEFAULT (integer)
Specifies that data is sent/retrieved to/from the server according to PDO::SQLSRV_ENCODING_SYSTEM if specified during connection. The connection's encoding is used if specified in a prepare statement. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ATTR_QUERY_TIMEOUT (integer)
A non-negative integer representing the timeout period, in seconds. Zero (0) is the default and means no timeout. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, and PDO::prepare.
PDO::SQLSRV_ATTR_DIRECT_QUERY (integer)
Indicates that a query should be executed directly, without being prepared. This constant can be passed to PDO::setAttribute, and PDO::prepare. For more information, see » Direct and Prepared Statement Execution.

As of 12/12/2014, Microsoft has officially released Version 3.1.

Support for 5.5 has 4 drivers
php_pdo_sqlsrv_55_nts.dll
php_pdo_sqlsrv_55_ts.dll
php_sqlsrv_55_nts.dll
php_sqlsrv_55_ts.dll

Note: Version 3.1 now supports PHP 5.5 and requires Microsoft ODBC Driver 11 (or higher)

An updated driver compatible with both PHP 7.0 and Linux is available on the PHP-7.0-Linux branch of https://github.com/Microsoft/msphpsql/

This is more up to date and supports some additional features over the ODBC / DBLIB drivers.

It is currently considered an 'Early Technical Preview' and hence has some limitations, but in my experience it has been stable.
