Apache httpd mod_proxy_fcgi php-cgi.exe No input file specified is very common when you try to use Apache HTTP Server's proxy_fcgi_module with PHP or other excutables as a CGI application to handle the FastCGI protocol on Windows systems.
mod_proxy_fcgi sets wrong SCRIPT_FILENAME with a starting slash, and the leading slash leads to a 404 error with a message No input file specified, as the FastCGI application php-cgi.exe doesn't know the right file path of the wrong-set SCRIPT_FILENAME which has a slash prefix.

We can also set other env variables using the ProxyFCGISetEnvIf directive.
I am using Apache httpd 2.4.39 and PHP 7.3.5 on Windows 7.
ProxyFCGIBackendType is introduced in Apache HTTP Server 2.4.26, if you're on previous versions of Apache httpd, you shoud comment out or remove this directive. |
