LVIII. Microsoft SQL Server functions

Introduction

   These functions allow you to access MS SQL Server database.

Requirements

   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.

Installation

   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.

Runtime Configuration

   The behaviour of these functions is affected by settings in php.ini.

   mssql.secure_connection    "0"     PHP_INI_SYSTEM
   mssql.max_procs            "25"    PHP_INI_ALL
   For further details and definition of the PHP_INI_* constants see
   ini_set().
