PHP 7.4.0RC6 Released!


La extensión SQLSRV se activa añadiendo el fichero DLL apropiado al directorio de extensiones de PHP y la entrada correspondiente al fichero php.ini. La descarga de SQLSRV viene con 8 ficheros controladores, cuatro de ellos son para el soporte de PDO. Si se está ejecutando PHP (PHP 5.3) no seguro a nivel de hilos se ha de utilizar el fichero php_sqlsrv_53_nts.dll. (Se debería usar una versión no segura a nivel de hilos si se utiliza IIS como servidor web). Si se está ejecutando PHP seguro a nivel de hilos se ha de utilizar el fichero php_sqlsrv_53_ts.dll. De forma similar, para PHP 5.4, se ha de usar php_sqlsrv_54_nts.dll o php_sqlsrv_54_ts.dll, dependiendo de si la instalación de PHP no es segura a nivel de hilos o sí lo es, respectivamente.

La versión más reciente del controlador se puede descargar aquí: » Descarga de SQLSRV 4.0. Si se necesita soporte para PHP 5.2 y/o PHP compilado con VC6, se ha de usar la versión 2.0 del controlador: » Descarga de SQLSRV 2.0.

Para más información sobre los requerimientos de SQLSRV, ver » Requerimientos del Sistema para SQLSRV.

La extensión SQLSRV solamente es compatible con PHP corriendo sobre Windows. Desde la versión 4.0 la extensión SQLSRV solo es compatible con PHP 7.0 corriendo sobre Linux o Windows.

Running PHP 7.2 on IIS 10, I had to use the IIS Web Platform Components wizard to install the Microsoft PHP drivers version 5.2 x64 to get this command to work.  Manually installing 4.0 drivers did not work.

SQLSRV doesn't use mssql_connect - it is it's own extension, therefore to connect you'd use sqlsrv_connect:

For some reason the default DLL files given at microsoft's website did not work for me. The author of this link : has compiled the same driver with different version of VC which worked for me. Just leaving a note for anyone who may be benefited

PHP Warning:  PHP Startup: Unable to load dynamic library '...\ext\php_sqlsrv_56_nts.dll' - %1 is not a valid Win32 application.

This error may occur if the Visual C++ runtime required by sqlsrv can not be found. In this case, "Visual C++ Redistributable for Visual Studio 2012 Update 4 (x86)" had to be installed for the x86 compiled PHP running on a x64 OS. For further investigations, have a look at Sysinternals Process Monitor.
