mkdir permission errors

["Wei, Alice J." <ajwei@xxxxxxxxxxx>]

Hi, Guys:

   I have a very strange incident here that may seem very stupid. Since the power went out last night, I have restarted my server. However, now the permission is never working right. I have set the permission of my htdocs folder iof my Apache server to 0755, and then started executing the following.

  $id=$_REQUEST['id'];
  $filename = "/usr/local/apache/htdocs/test";

if (file_exists($filename)) {

     mkdir("/usr/local/apache/htdocs/test/$id", 0777) or die ("<p>Cannot create directory</p>");
    chmod("/usr/local/apache/htdocs/test/$id", 0777);
     mkdir("/usr/local/apache/htdocs/test/$id/contours", 0755) or die ("<p>Cannot create directory</p>");
     chmod ("/usr/local/apache/htdocs/test/$id/contours",0777);
     mkdir ("/usr/local/apache/htdocs//$id/beamdata", 0777) or die ("<p>Cannot create directory</p>");
      mkdir("/usr/local/apache/htdocs//$id/schemadata", 0777) or die ("<p>Cannot create directory</p>");
      mkdir("/usr/local/apache/htdocs/$id/plandata", 0777) or die ("<p>Cannot create directory</p>");

}

else {

  mkdir("/usr/local/apache/htdocs/test", 0777) or die ("<p>Cannot create directory http://192.168.10.63/TPU</p>");
}

However, the error always bumped me with Cannot create directory http://192.168.10.63/test.
I went into my error logs, and it continuously give me this:

[Mon Jul 14 14:51:07 2008] [error] [client 192.168.10.63] PHP Warning:  mkdir() [<a href='function.mkdir'>function.mkdir</a>]: Permission denied in /usr/local/apache/htdocs/file_linux.php on line 23

Can anyone please give me a hint on what could be wrong here? I have set my parent directory to 0755 already.

Thanks in advance.
