There are 7 values that can be returned. Here is a list of them and what each one means
block: block special device
char: character special device
dir: directory
fifo: FIFO (named pipe)
file: regular file
link: symbolic link
unknown: unknown file type
I use the CLI version of PHP on Windows Vista. Here's how to determine if a file is marked "hidden" by NTFS:
<?php
function is_hidden_file($fn) {
$attr = trim(exec('FOR %A IN ("'.$fn.'") DO @ECHO %~aA'));
if($attr[3] === 'h')
return true;
return false;
}
?>
Changing <?php if($attr[3] === 'h') ?> to <?php if($attr[4] === 's') ?> will check for system files.
This should work on any Windows OS that provides DOS shell commands.
filetype() does not work for files >=2GB on x86 Linux. You can use stat as a workarround:
$type=trim(`stat -c%F $file`);
Note that stat returns diffenerent strings ("regular file","directory",...)
