in programing elisp in emacs, i can press “Ctrl+h f” to lookup the doc for the function under cursor. is there such facility when coding in perl, python, php?

Yes, try C-h S (or similarly <f1> S):

(info-lookup-symbol SYMBOL &optional MODE) Display the definition of SYMBOL, as found in the relevant manual. When this command is called interactively, it reads SYMBOL from the minibuffer.

Note that `the relevant manual' means an info file. With recent
emacsen on an Ubuntu distro, python arrives with info files and
everything is well configured. It also works with bash, latex, perl,
scheme, elisp, awk, texinfo, makefile, libc, or any info file with an
index.
