Description of problem:
I use a stock FC3, Apache and PhpWiki (edit lib/config.php to use 
flat files). When PhpWiki tries to update a "hitcount" file, it 
fails, and the following audit event is logged:

Jan 19 10:12:58 localhost kernel: audit(1106147578.393:0): avc:  
denied  { append } for  pid=4702 exe=/usr/sbin/httpd 
name=hitcount.data dev=hda4 ino=1802851 
scontext=user_u:system_r:httpd_t 
tcontext=root:object_r:httpd_sys_script_rw_t tclass=file

Version-Release number of selected component (if applicable):
PhpWiki 1.2.7 (http://sourceforge.net/projects/phpwiki/)

How reproducible:
Reliably

Steps to Reproduce:
1. Download PhpWiki 1.2.7 from 
http://sourceforge.net/projects/phpwiki/ and unpack into apache 
directory (/var/www/wiki)

2. Edit /var/www/wiki/lib/config.php to use flat files:
$WhichDatabase = 'file'

3. Change the location of pages from default '/tmp' (look under 
elseif ):
$DBdir = '/var/www/wiki/contents';

4. Change the file context of "contents" to httpd_sys_script_rw_t:
chcon -R root:object_r:httpd_sys_script_rw_t '/var/www/wiki/contents'

5. Visit URL http://localhost/wiki
  
Actual results:
At the end of the page:
WikiFatalError
Error while writing page 'hitcount.data' 

Expected results:
No error

Additional info:
This could be a problem with Apache, because if it were running in 
the 'httpd_sys_script_t' domain (instead of 'httpd_t') while 
executing PHP scripts, the following rule would allow the append:

/etc/selinux/targeted/src/policy.conf:
allow httpd_sys_script_t httpd_sys_script_rw_t:{ file ...} {... 
append ...}

But I don't know SELinux that well.
