Adding php to the "include_path" in the php.ini???

Hi! After doing many testing for hte fsockopen() bugs with PHP developers which is now fixed. I just happen to noticed that in the middle of those testing when I do the PHP installation after doing the usual configure and make. What I noticed is that it asked me to .. --snip-- You may want to add: /usr/local/bin/php to your php.ini include_path --snip-- Anyone know what so important about it? Since that PHP is already compiled with Apache and that PHP work, so what is the purpose of adding the binary php in /usr/local/bin/php to the php.ini configuration when it come to using the website?? Thanks, FletchSOD
