Permission denied, although permissions are right

Hi, I'm trying to open a file (using fopen) in the /tmp directory which is owned by user 'zapman'. The php script is also owned by user 'zapman'. However, when I try to run it, I get : Warning: fopen("/tmp/1.dat","r") - Permission denied in /documents/zapman/html/openfile.php on line 5 If I do a ps auwx | grep http, I get : root 20341 0.0 0.0 15100 56 ? S 12:46 0:02 /usr/local/apache/bin/httpd -DSSL nobody 20342 0.6 3.3 18276 4184 ? S 12:46 0:26 /usr/local/apache/bin/httpd -DSSL nobody 20343 0.8 4.6 20008 5936 ? S 12:46 0:35 /usr/local/apache/bin/httpd -DSSL nobody 20344 0.3 3.2 16100 4108 ? S 12:46 0:15 /usr/local/apache/bin/httpd -DSSL So the main process is running as root, the rest is running as nobody... that's the way to do it, right ? Or should I run Apache as root (which I don't like at all !) ? Greetings, Wim Godden
