When variable names get too long or you have to juggle a lot of nested arrays it gets cumbersome to repeat the same variables over and over again while programming.
In example you have the code below and want to debug what value you
actually parsed to
some_function(). You have point at
^ and now
all you have to write is repeat the variable...
php-extras and you just hit C-c C-$ and it will
insert the previous variable (including array indexes).
If you prefix the command (i.e. C-u 3 C-c C-$) it will search back 3 variables and with negative prefix arguments it will search forward.
eldoc-mode is a nice minor mode that ships with Emacs. It will
display a function tip in the mini buffer showing the function and its
arguments for the function at point. That is if you provide a function
to look up the function definition.
php-extras provides such a function for looking up all the core PHP
php-extras-generate-eldoc will download the PHP manual
from php.net and extract the function definitions
(slow) and store them in a hash table on disk for you. Your Emacs must
be build with libxml2 and Emacs should be able to find the
executable somewhere along its

php-extras as an ELPA package the hash table is
already generated for you.

The easiest way to install
php-extras is probably to install it via
the ELPA archive at
ELPA (package.el) is part of Emacs 24. For Emacs 23 see Marmalade for installation instructions.
The version number of the ELPA package will have the date appended when the package was build and hence the date the documentation got extracted from php.net.
I really recommend that you install this package via ELPA as described above.
If you insist on installing it manually try to follow this recipe:
Place the folder with the files somewhere on your disk.
Add this to your
(add-to-list 'load-path "/somewhere/on/your/disk/php-xtras") (eval-after-load 'php-mode (require 'php-extras))
Either restart your Emacs or at evaluate the
