I ran into a strange problem this morning. Suddenly I am getting an
error that str_word_count is undefined, even though it has been working
for the past few months. Anyone know why this may be? Nothing in the my
code has changed at all.
I did phpinfo() to check the server and it is running 4.2.
I would recommend using your .htaccess file, or ini_set, or something
else to set your include_path variable
Thanks Joel, that worked nicely.

You could create a function to do this. Just think of it in small steps.
You can use the string replace function to replace certain parts with
