Fatal error: Call to undefined function mssql_connect() in php [duplicate]

This question already has answers here: PHP Fatal error: Call to undefined function mssql_connect() (3 answers) Closed 3 years ago.

I'm running Windows Server, MS Sql and IIS6. I am trying to connect php to ms sql database, and I keep getting the following error from the script

Fatal error: Call to undefined function mssql_connect() in .... on line x

I have install zend studio in C:\Program Files\Zend\ZendStudio-5.5.0 directory. Configure IIS server and set the path variable to ;C:\Program Files\Zend\ZendStudio-5.5.0\bin\php5 also. The zend studio folder contains php4 and php5 inside the bin dir. I have added extension=php_mssql.dll in the php.ini file which is inside the C:\Program Files\Zend\ZendStudio-5.5.0\bin\php5 folder. And added php_mssql.dll in the ext dir. php.ini file is placed in windows path C:\W开发者_Go百科INDOWS also.

To get changes made to php.ini to take effect, you must stop and start the IIS web service.

Also, mssql requires: ntwdblib.dll to be available on the Windows PATH. It is better to add the php folder to the Windows PATH instead of moving any files around. Re-logon or reboot your computer to get any changes made to the Windows PATH statement to take effect.

mssql_* API are no longer available on recent version of PHP This extension is not available anymore on Windows with PHP 5.3 or later

you may need fix and compile yourself as it does not included in the open-source package.
