Hi,

in PHP 4.2.2 I get the following error when I want to include '/etc/passwd':

Warning: SAFE MODE Restriction in effect. The script whose uid is 500 is not allowed to access /etc/passwd owned by uid 0 in /home/httpd/htdocs/i.php on line 4

Warning: Failed opening '/etc/passwd' for inclusion (include_path='.:/usr/local/lib/php') in /home/httpd/htdocs/i.php on line 4

I just upgraded to PHP 4.3.0 and the file will be included without any error message!

readfile() performs right:

Warning: readfile() [function.readfile]: SAFE MODE Restriction in effect. The script whose uid is 500 is not allowed to access /etc/passwd owned by uid 0 in /home/httpd/htdocs/i.php on line 4

Warning: readfile(/etc/passwd) [function.readfile]: failed to create stream: Inappropriate ioctl for device in /home/httpd/htdocs/i.php on line 4

I am using PHP Version 4.4.4-8+etch4 and i am experiencing a similar 
problem.
When i open a file with readfile(), safe mode doesn't allow me to 
open the file only if it is contained in a directory with a 
different UID.
If the script and the file to open are owned by different users but 
are located in the same directory, or the file to open is located in 
a directory owned by the same user of the script, i'll be able to 
read the file.
