Incorrect - at least in the case of Python for iOS.
Python for iOS is the python interpreter, with a GUI, plain and simple. You can put the device in Airplane mode / disable all network connectivity and it will still work.
The same goes for the BASIC and Lua interpreters I have on it, and many others.
The reason PHP has shown up is the same reason these other languages did: The code they run is interpreted (scripting languages), it is not compiled to native ARM code via JIT/compiler on the device.
In addition, for every one of these that Apple allows on the App Store, almost every developer of one will tell you that Apple will keep you from making it easy to import code into the device. Rarely have I ever seen iTunes Document loading enabled/allowed for one of these apps (so you could just drag-n-drop code into it).
Exporting is allowed, but Apple doesn't want to make it "easy" for people using these tools to import arbitrary code (like, say, an interactive torrent client).
