I have 3 versions of PHP installed on my system in 3 folders: C:/PHP738, C:/PHP739, C:/PHP740. I removed all php.ini files and then my script fails because odbc is not loaded. I then added back the php.ini into C:/PHP738 (which has odbc enabled) and then the PHP 7.4.0 web server loads the php.ini info from folder C:/PHP738 and the script works. It must be something in Windows or IIS that is finding a copy of php.ini in a cache and using it instead of what is in the folder for the version of PHP being used by IIS. Sorry for all the grief that I have caused, but this was a really strange situation. ------------------------------------------------------------------------ [2019-08-18 10:20:57] cmb@php.net With the additional information, this looks like ODBC is not compiled statically. You can verify that with ProcessExplorer[1] which probably shows that php_odbc.dll is loaded. Anyhow, I actually tested with IIS now, and the ODBC extension is only available if I add extension=odbc to php.ini (and restart IIS). So this looks like a configuration issue on your machine.
