Visualizzare un sorgente PHP via web

E' possibile visualizzare il sorgente di un file php con la syntax highlighting, in due modi:

1. Copiare il file .php in .phps e visualizzarlo nel browser. Se il webserver è Apache (2), verrà mostrato il source, a colori.

1. Usare questo script: http://www.zend.com/codex.php?id=203&single=1

/******************************************
#  File:  view_source.php
#  Description: Script to view code with highligths.
#                Link to this file with 
#                "view_source.php?source=/mypath/myfile.php"
#                
#                Makes a copy of the php file and names it phps.
#                And then redirects the browser to the new phps file.
#                phps files are automaticly code highlighted and displayed
#                if you are using Apache.
