permission failure with fopen

[<cr.vegelin@xxxxxxxxx>]

Hi All,

I get strange permission problems with fopen() ...

$directory = "somedir";
$filename = $directory . "/somefile.txt";
$handle = fopen($filename, "w");    // gives: failed to open stream: Permission denied 

but,
- fileperms($directory) gives: 0777 and is_writable($directory) gives "writable"
- fileperms($filename) gives 0666  and is_writable($filename) gives "'writable"

I'm testing on Windows XP SP2 with PHP 5.2.0

Any idea how to solve this ?

TIA, Cor
