At last it's solved. It's because of SELinux settings.
I am using GNOME. Go to System --> Administration --> Security Level
and Filewall. Click SELinux tab. Expand "HTTPD Service", and check
"Allow HTTPD scripts and modules to connect to the network". Then
expand "Other", and check "httpd_enable_ftp_server". Finally click OK
button to close the "Security Level Configuration" dialog.
After the above changes, the php web page will work.
Thanks!
