php文件上传：在列表中使用unlink从服务器中删除元素

I have this php to upload a file, I want add a button at the right of each element of the list where if I click on I delete the element from the list and from the server. Is it possible? Thanks

<html>
<body>

<form action="" method="post" enctype="multipart/form-data">
    Select a file to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Load" name="submit">
</form>

<div>

    <?php
    $dir    = 'up/';
    $files = scandir($dir);
    echo 'uploaded files<br><hr>';
    $i = 1;
    foreach ($files as $key)
    {
        if ($i>2)
        {
            $j = $i-2;
            echo $j."&nbsp&nbsp<a href='up/".$key."'>".$key."</a><hr>";
        }
        $i++;
    }
    echo ' ';
    ?>

</div>
</body>
</html>

<?php
if (isset($_POST['submit']))
{
    echo '<center><h1>upload succesful!</h1></center>';
    $structure = 'up/';
    $target_file = $structure.basename($_FILES["fileToUpload"]["name"]);
    move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
?>

    You can do this by unlink the files that you need to do it.

    Here are the easy steps for you ;)

    Step 1 : Create an anchor tag which gives the path of the image/file

    <a href='index.php?delete=up/<?php echo $key?>'>Delete Now</a>

    Step 2 : On clicking the anchor tag, the page will be redirect to itself with the file's name

    Step 3 : Get the file and unlink (delete) it

    unset($_GET['delete']);

    Step 4 : Refresh the page once to have a fresh list of files.

    header("Refresh:0; url=".$url);

    Here's the Eval for you and Here's the code that you need to have 

    <html>
<body>

<form action="" method="post" enctype="multipart/form-data">
    Select a file to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Load" name="submit">
</form>

<div>

    <?php
    error_reporting(0);
    session_start();
    $dir    = 'up/';
    $files = scandir($dir);
    echo 'uploaded files<br><hr>';
    $i = 1;
    foreach ($files as $key)
    {
        if ($i>2)
        {
            $j = $i-2;
            echo $j."&nbsp&nbsp<a href='up/".$key."'>".$key."</a>";
    if (isset($_GET['delete'])) 
    {
        unlink($_GET['delete']);

        $_SESSION['delete'] = $_GET['delete'];
        unset($_GET['delete']);
        $url = $_SERVER['SCRIPT_NAME'].http_build_query($_GET);
        header("Refresh:0; url=".$url);
    }
?>
   <a href='index.php?delete=up/<?php echo $key?>'>Delete Now</a>
            <hr>
            <?php
        }
        $i++;
    }

    ?>

</div>
</body>
</html>

<?php

if (isset($_POST['submit']))
{
    echo '<center><h1>upload succesful!</h1></center>';
    $structure = 'up/';
    $target_file = $structure.basename($_FILES["fileToUpload"]["name"]);
    move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
?>
