Note: The PEAR Coding Standards applies to code that is to become a part of PEAR, either distributed with PHP or available for download via PEAR's install tool.


Use an indent of 4 spaces, with no tabs. If you use Emacs to edit PEAR code, you should set indent-tabs-mode to nil. Here is an example mode hook that will set up Emacs according to these guidelines (you will need to ensure that it is called when you are editing PHP files):
(defun php-mode-hook ()
  (setq tab-width 4
        c-basic-offset 4
        c-hanging-comment-ender-p nil
	 (and (string-match "/\\(PEAR\\|pear\\)/" (buffer-file-name))
	      (string-match "\.php$" (buffer-file-name))))))

Here are vim rules for the same thing:
set expandtab 
  set shiftwidth=4 
  set tabstop=4
