phpinfo returns a permission error

PHP list, I wanted to adjust my register global settings in my php.ini file. I found instructions on this page: http://www.dmcinsights.com/phpmysql/phpini.php The first thing it says to do is take a look at the results of phpinfo(); to see where the php.ini file actually is. So I created a phpinfo.php file, put in the following code: <?php phpinfo(); ?> ... and then accessed it through FireFox at localhost. To my surprise, I got the following error message: Warning: Unknown(/home/dave/web_sites/phpinfo.php): failed to open stream: Permission denied in Unknown on line 0 Warning: (null)(): Failed opening '/home/dave/web_sites/phpinfo.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0 It looks to be a permissions issue. But who has permission if not me, and how is permission an issue when I'm just looking at the file through a browser? By the way, I'm using PHP 4.4.0-3 on Ubuntu 5.10. Any advice or help would be much appreciated. Thank you. -- Dave M G
