删除名为“.html”的文件

Question

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!";
}
