Here is how to resolve the no input file specified error with PHP and IIS. When you host your PHP website on Windows Server IIS, you may receive an "No input file specified" error message, when a HTTP request is made to non-existing .php files. When this happens you probably have no Request Restrictions configured in IIS' PHP handler settings.
In order to fix the no input file specified PHP error, you have to configure Request Restrictions in IIS for the *.php handler. In IIS Manager, open up the Handler Mappings under your server node. Scroll down to Name PHP, or Path *.php, and double click to open up its properties. See the image below.
Click Request Restrictions to get the following screen where you can configure and set handler mappings:

Hi, my name is Jan. I am not a hacker, coder, developer or guru. I am merely an application manager / systems administrator, doing my daily thing at Embrace – The Human Cloud. In the past I worked at CLDIN (CLouDINfra) and Vevida. With over 20 years of experience, my specialties include Windows Server, IIS, Linux (CentOS, Debian), security, PHP, websites & optimization. I blog at https://www.saotn.org.
None of these solutions worked for me. At this point, I need to find something other than PHP to use in web pages. I’m tired of this problem occurring over and over again. PHP is a defective product. Any suggestions?
FYI, I had a similar “No input file specified” problem on my Windows IIS server. The solution was to DISABLE the “doc_root” setting in my php.ini file. After doing that and running an IISRESET everything worked again.
