PHP CLI & IDE
There are a number of PHP IDEs that require PHP CLI. For example NuSphere IDE, Zend Studio IDE, ActiveState Komodo IDE require to have PHP CLI or PHP CGI installed on your system in order to do real-time syntax check of your scripts.
- Komodo allows you to run your scripts in CGI environment.
- NuSphere has command line tab.
- Zend Studio has PHP CLIs both version 4 and version 5 installed within the IDE, so you should not bother about it.
As you see, all popular commercial products are at least dependent on PHP CLI.
