Call to undefined function sqlsrv_connect() with WAMP

问题

I know that this question has already been asked several times on this website but I'm seriously starting to wonder wheter I'm crazy or not.

My configuration : WampServer 2.5 64bits (PHP 5.5.12, Apache 2.4.9)

My steps:

Download Microsoft Driver SQLSRV32.exe from https://www.microsoft.com/en-us/download/details.aspx?id=20098
Extract the files from the .exe downloaded on my desktop
Copy php_sqlsrv_55_ts.dll and php_pdo_sqlsrv_55_ts.dll into C:\wamp\bin\php\php5.5.12\ext
Edit C:\wamp\bin\php\php5.5.12\php.ini adding "extension=php_pdo_sqlsrv_55_ts.dll" and "extension=php_sqlsrv_55_ts.dll"
Edit C:\wamp\bin\apache\apache2.4.9\bin\php.ini adding "extension=php_pdo_sqlsrv_55_ts.dll" and "extension=php_sqlsrv_55_ts.dll"
Restart all services (I even tried to restart my computer, but nothing works)

I still get the error... So what am I missing to make this work ?

回答1:

Installing just the PHP extension is not enough, you also need to install Microsoft® ODBC Driver 11 for SQL Server® - Windows

The ODBC drivers can be found here

And newer drivers can be found here

Also the best way to ensure you are editing the correct php.ini file is to use the wampmanager menus. So in future do :-

wampmanager -> PHP -> php.ini

This will load the correct php.ini into yoru editor.

C:\wamp\bin\php\php{version}\php.ini is used only by PHP CLI

C:\wamp\bin\apache\apache{version}\bin\php.ini is used only by PHP when running under Apache

回答2:

Did you try to modify php.ini using the wamp interface ?

I know it sounds strange but sometimes the result is different than editing directly the file using the browser. Wamp manages those files in a strange way, give it a try...

回答3:

I finally found what was causing the problem. My Wamp was in 64 bits but the sqlsrv driver only works with 32 bits version. Now it works perfectly.
