FTP Is_File

[Garethp]

Ok, so is_file doesn't seem to work with FTP connections, any idea why? Here is my code

 

<?php

session_start();

//Connect to the FTP server
$ftp = ftp_connect('xxxx');
//Login to the FTP server
$login = ftp_login($ftp, 'xxxx', 'xxxx');

if(!$login) 
{
echo "Error";
exit();
}

if(!isset($_SESSION['Folder']))
{
$_SESSION['Folder'] = "public_html";
}

if(isset($_GET['folder']))
{
$_SESSION['Folder'] .= "/" . $_GET['folder'];
}

$Folder = $_SESSION['Folder'];

if(preg_match("~\.\.$~", $Folder))
{
$Folder = preg_replace("~^(.*?)/?\.\.?$~", "$1", $Folder);
$_SESSION['Folder'] = $Folder;
}

ftp_chdir($ftp, $Folder);

if(isset($_GET['action']) && $_GET['action'] == "up")
{
$_SESSION['Folder'] = preg_replace("~^(.+?)/.+$~", "$1", $_SESSION['Folder']);
ftp_cdup($ftp);
}

$List = ftp_nlist($ftp, "");
unset($List[array_search('.', $List)]);
unset($List[array_search('..', $List)]);
natcasesort($List);

echo "<a href=\"?action=up\">Parent Folder</a><br><br><b>Folders</b><br>";
foreach($List as $v)
{
if(is_file($v))
	{
	continue;
	}
echo "<a href=\"?folder=$v\">$v</a><br>";
}
echo "<br>";

echo "<b>Files</b><br>";
foreach($List as $v)
{
if(!is_file($v))
	{
	continue;
	}
echo $v . "<br>";
}
echo "<br>";

ftp_close($ftp);
?>

 

With this code, I only get index.php as a file, and everything else as a folder. However, if I use is_dir instead, it works. Why is this?
