These functions allow you to access MS SQL Server database.
Requirements for Win32 platforms.
The extension requires the MS SQL Client Tools to be installed on the system where PHP is installed. The Client Tools can be installed from the MS SQL Server CD or by copying ntwdblib.dll from \winnt\system32 on the server to \winnt\system32 on the PHP box. Copying ntwdblib.dll will only provide access. Configuration of the client will require installation of all the tools.
Requirements for Unix/Linux platforms.
To use the MSSQL extension on Unix/Linux, you first need to build and install the FreeTDS library. Source code and installation instructions are available at the FreeTDS home page: http://www.freetds.org/
Note: In Windows, the DBLIB from Microsoft is used. Functions that return a column name are based on the dbcolname() function in DBLIB. DBLIB was developed for SQL Server 6.x where the max identifier length is 30. For this reason, the maximum column length is 30 characters. On platforms where FreeTDS is used (Linux), this is not a problem.
The MSSQL extension is enabled by adding extension=php_mssql.dll to php.ini.
To get these functions to work, you have to compile PHP with --with-mssql[=DIR], where DIR is the FreeTDS install prefix. And FreeTDS should be compiled using --enable-msdblib.
The behaviour of these functions is affected by settings in php.ini.
Table 1. MS SQL Server configuration options
|mssql.timeout||"60"||PHP_INI_ALL||Available since PHP 4.1.0.|
|mssql.batchsize||"0"||PHP_INI_ALL||Available since PHP 4.0.4.|
|mssql.datetimeconvert||"1"||PHP_INI_ALL||Available since PHP 4.2.0.|
|mssql.secure_connection||"0"||PHP_INI_SYSTEM||Available since PHP 4.3.0.|
|mssql.max_procs||"25"||PHP_INI_ALL||Available since PHP 4.3.0.|
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
