删除名为“.html”的文件

I accidentally created a file with no name http://website.com/myFolder/.html,

now, in the control panel of my webhost, this file is not listed, I cannot see or delete it...

but I can see it using this "myList.php" file: (http://website.com/myFolder/myList.php):

<?php
echo "<ol>";
if ($handle = opendir('.')) {
    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {
            echo '<li><a href="'.$entry.'" target="_blank">'.$entry.'</a></li>';
        }
    }
    closedir($handle);
}
echo "</ol>";
?>

This "myList.php" file outputs all the files present in the directory: http://website.com/folder/
also the file with no name http://website.com/myFolder/.html

How can I delete this file?

I tried to create another .php file called http://website.com/myFolder/myDelete.php,
and use the php function unlink():

<?php

$path = "../myFolder/.html";
if(file_exists($path)){
    if (is_file($path)){
        //unlink($path);
        if (!unlink($file)){
            echo ("Error deleting".$path);
        }else{
            echo ("Deleted".$path);
        }
    }
}

?>

But it doesn't work.

Files and directories that begin with . are considered "hidden" on *nix systems. You can see them with ls -la but not with just ls.

Try changing the $file variable to just be the name of the file ".html". Make sure to use the $file variable for the delete - this is not defined in your example.

$file = ".html";

if ( file_exists( $file ) ){
    if ( ! unlink( $file ) ){
        echo "Error deleting '$file'" );
    } else{
        echo "Deleted '$file'";
    }
} else {
    echo "File '$file' does not exist!";
}

$path = "../myFolder/.html";
if(file_exists($path)){
    if (is_file($path)){
        //unlink($path);
        if (!unlink($file)){
                    ^^^^^----undefined variable

Why all of that when you could just have

unlink('.html');

? Your unwanted file is in the same directory as your myDelete.php script, so the rest of all that is pointless.

The one comment suggested you use FTP, you should have FTP access to your server then you can simply delete through FTP.
