Description:
------------
I cannot open files for writing with fopen. fileperms function on existing file returns FALSE.


i checked file permissions, turned safe mode off to no avail. the same script runs on machines with  FC1 and php 4.3.8 just fine.

fopen for reading works fine.

I can read/write the same files with perl cgi scrips but not with php 






Reproduce code:
---------------
my test script

<?php
$filename = '/var/www/html/test.txt';
$content = "Add this to the file\n";


if (file_write($filename,$content)) echo "Success";

   function file_write($filename, &$content) {

     if (!$fp = @fopen($filename, "w")) {
           echo "Cannot open file ($filename)";
           exit;
       }
       if (fwrite($fp, $content) === FALSE) {
           echo "Cannot write to file ($filename)";
           exit;
       }
       if (!fclose($fp)) {
           echo "Cannot close file ($filename)";
           exit;
       }

    return true;
   }

?>


Expected result:
----------------
Success

Actual result:
--------------
Cannot open file (/var/www/html/test.txt)
