This is be similiar to bug #21958 but not the same OS and not the same PHP version.

With AIX 4.3.3 and PHP 4.3.1.

With safe_mode on , I cannot create a file with neither touch nor fopen nor mkdir. (With safe_mode off, the creation works).

Apache is running under user "web" and group "web".
I have the directory /web/hee_dev whose owner is web.web with permissions rwxr-s---

I have the script testing.php located in that directory:

   <?
     $fp=fopen("filetocreate","w+");
   ?>

If the file "filetocreate" does not already exist, I get the following error while executing the script:
 
           Warning: Unable to access filetocreate  
           in /web/hee_dev/testing.php on line 2

           Warning: fopen("filetocreate", "w+") - No such 
           file or directory in /web/hee_dev/testing.php on 
           line 2

If the file already exists, I can open it without any problem.

I had read somewhere in the bug database that this should be solved by now, but with 4.3.1, it still produces this error.
