Deleting the folder and not the files

Question

I can’t identify where I’m going wrong..

The Code below is deleting my uploads folder and is where the files are coming from, but actually I would like you to delete the uploads/folder files and not the uploads folder. Any possible help?

EDIT: It is not deleting the entire folder, but rather the files in the subfolders: "uploads/subfolder/file.extensao <- is the.extensao file that should be deleted only.

Thanks in advance!

<?php
$src = 'uploads';
$dst = 'bkp/';

rcopy($src, $dst);  // Call function 
// Function to Copy folders and files       
function rcopy($src, $dst) {
    if (file_exists ( $dst ))
        rrmdir ( $dst );
    if (is_dir ( $src )) {
        mkdir ( $dst );
        $files = scandir ( $src );
        foreach ( $files as $file )
            if ($file != "." && $file != "..")
                rcopy ( "$src/$file", "$dst/$file" );

    } else if (file_exists ( $src ))
        copy ( $src, $dst );
                    rrmdir ( $src );
}       

// Function to remove folders and files 
function rrmdir($dir) {
    if (is_dir($dir)) {
        $files = scandir($dir);
        foreach ($files as $file)
            if ($file != "." && $file != "..") rrmdir("$dir/$file");
        rmdir($dir);
    }
    else if (file_exists($dir)) unlink($dir);
}
?>
