PHP 7 on IIS: Call_user_function could not be located

Question

I am trying to use the Microsoft SQL Server drivers with PHP 7.1 Not Thread Safe x64 on Windows 2012 R2 64-bit server.

No matter what I do I am getting an error when I run php from a admin command prompt

Warning: PHP Startup: Unable to load dynamic library 'ext\php_pdo_sqlsrv_7_nts.dll' - The specified procedure could not be found.

Additionally it display a windows pop up that states

The procedure entry point call_user_function could not be located in the dynamic link library C:\PHP7\ext\php_pdo_dqlsrv7_nts_x64.dll

I have verified that the php.ini is pointing to a file that exists, because if I rename the .dll file, the error messages changes to "specified module could not be found", instead of specified procedure.

I have installed Microsoft Visual C++ runtime 15 x64 as required by PHP 7.

I have installed Microsoft ODBC driver 13 as required by the Microsoft SQL Server driver.

I have rebooted the server twice.

There is nothing else I can think to even try. The Microsoft WinCache.dll is loading and working fine in PHP, as verified by phpinfo.

I'm also getting near same errors on my Win10 box trying to get PHP 7.3.10 to use redis v3.1.0 — bkwdesign, Oct 16 '19 at 14:08

Confirmed what @MEmerson said above. You need to downgrade PHP to 7.0.X(?) - I used 7.0.12.

Complete Setup:

Windows 10 Pro
PHP X64 7.0.12 TS (Bitnami WAMP Stack)
Microsoft ODBC Driver 13.1 for SQL Server (https://msdn.microsoft.com/en-us/library/mt703139(v=sql.1).aspx)
Microsoft Drivers for PHP for SQL Server 4.0 (https://www.microsoft.com/en-ca/download/details.aspx?id=20098)

Same drivers with PHP X64 7.1.0 produced the error you are getting.

Microsoft Drivers 4.3 for PHP for SQL Server are now available. These drivers contains files for PHP 7.1 - php_pdo_sqlsrv_71_nts_x64.dll etc. I've successfully managed to connect to SQL server.

Had similar error when tried to use httpd (Apache), PHP 7.2.2, Microsoft ODBC driver 11 on MS Windows Server 2012. The text of error was:

The procedure entry point call_user_function could not be located in the dynamic link library php_pdo_sqlsrv_7_ts_x64.dll.

when I called php -m to check modules.

So I have downloaded Windows-7.2.zip from https://github.com/Microsoft/msphpsql/releases and used thread-safe dlls from it.

php -m works now as it should without giving error.

It happened to me today while enabling the extensions in the IIS, where I by mistake enabled different versions for pdo & driver extensions (E.g. php_sqlsrv_7_nts_x86.dll for PHP 7.0 & php_pdo_sqlsrv_72_nts_x86.dll for PHP 7.2).

Usually the package that you download from Microsoft that contains Microsoft Drivers 5.3 for PHP for SQL Server has all the PHP extensions versions. https://www.microsoft.com/en-us/download/details.aspx?id=57163

Just make sure you enable both extensions for the same versions to avoid that error.
