Putting @ in front of the filetype() function does not prevent it from raising a warning (Lstat failed), if E_WARNING is enabled on your error_reporting.

The most common cause of filetype() raising this warning and not showing a filetype() in the output (it actually returns NULL) is, if you happened to pass just the 'Dir or File Name' and not the complete "Absolute or Relative Path" to that 'file or Dir'. It may still read that file and return its filetype as "file" but for Dir's it shows warning and outputs NULL.
eg:
$pathToFile = '/var/www';
$file = 'test.php';
$dir = 'somedir';

Output for filetype($file) will be returned as 'file' and possibly without any warning, but for filetype($dir), it will return NULL with the warning "Lstat failed", unless you pass a complete path to that dir, i.e. filetype($pathToFile.'/'.$dir).

This happened to me and found this solution after a lot of trial and error. Thought, it might help someone.

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",...)

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.

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
