Tags are extremely valuable and are used for navigation of source code inside the editors like vi, emacs,
CRiSP, NEdit
etc... If you had programmed a lot in C, C++ or Java you might have used the
ctags program to
create tags. To see the online manual page, type ''man ctags'' at linux/unix bash prompt.
The
ptags program for PHP is given below, which you can use to create the tags for PHP source code. Your
productivity will improve 3 to 4 times if you use
ptags.
