如何在文件托管站点上使用PHP删除目录中的文件？

Question

I am trying to make a simple file hosting site for my family, a couple friends and I to use. I have the entire system setup except one thing... I cannot find a way to let the user delete a file without having to access the FTP. I will post the code in which I use to list the files to the user below. I want to have a delete button automatically generated for each new file the user uploads.

Code to list files:

$directory = 'uploads/' . $_SESSION['user'] . '/';
if ($handle = opendir($directory)) {
    echo '<h3>Your files are listed below</h3>';    
    while ($file = readdir($handle)) {
        if ($file != '.' && $file != '..') {
            echo '<a target="_blank" href="' . $directory . '/' . $file . '">' . $file . '<br>';    
        }
    }
}

$directory = 'uploads/' . $_SESSION['user'] . '/';

if(isset($_REQUEST['DelFile'])) {
    $DeleteFile = $_REQUEST['DelFile'];
    if(file_exists($directory.$DeleteFile)) {
        @unlink($directory.$DeleteFile);
        header("location:SamePageURL.php?msg=1");
    } else header("location:SamePageURL.php?msg=2");
}

if ($handle = opendir($directory)) {
echo '<h3>Your files are listed below</h3>';    
    while ($file = readdir($handle)) {
        if ($file != '.' && $file != '..') {
            echo '<a target="_blank" href="'.$directory.'/'.$file.'">' . $file.' <a href="SamePageURL.php?DelFile='.$file.'">Delete</a> <br>';  
        }
    }
}

if(isset($_REQUEST['msg'])) {
    $Message = $_REQUEST['msg'];
    if($Message == 1) echo "File deleted sucessfully";
    else if($Message == 1) echo "File not found";
}
