This function will allow you to delete any folder (as long as it's writable) and it's files and subdirectories.

这个函数允许您删除任何文件夹(只要它是可写的)以及它的文件和子目录。

function Delete($path)
{
    if (is_dir($path) === true)
    {
        $files = array_diff(scandir($path), array('.', '..'));

        foreach ($files as $file)
        {
            Delete(realpath($path) . '/' . $file);
        }

        return rmdir($path);
    }

    else if (is_file($path) === true)
    {
        return unlink($path);
    }

    return false;
}

Or without recursion using RecursiveDirectoryIterator:

或者不使用RecursiveDirectoryIterator进行递归:

function Delete($path)
{
    if (is_dir($path) === true)
    {
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::CHILD_FIRST);

        foreach ($files as $file)
        {
            if (in_array($file->getBasename(), array('.', '..')) !== true)
            {
                if ($file->isDir() === true)
                {
                    rmdir($file->getPathName());
                }

                else if (($file->isFile() === true) || ($file->isLink() === true))
                {
                    unlink($file->getPathname());
                }
            }
        }

        return rmdir($path);
    }

    else if ((is_file($path) === true) || (is_link($path) === true))
    {
        return unlink($path);
    }

    return false;
}

You need to loop around the folder contents (including the contents of any subfolders) and remove them first.

您需要对文件夹内容(包括任何子文件夹的内容)进行循环，并首先删除它们。

There's an example here: http://lixlpixel.org/recursive_function/php/recursive_directory_delete/

Be careful with it!!!

小心! ! !

Here's a script that will do just what you need:

这里有一个脚本可以满足你的需要:

/**
 * Recursively delete a directory
 *
 * @param string $dir Directory name
 * @param boolean $deleteRootToo Delete specified top-level directory as well
 */
function unlinkRecursive($dir, $deleteRootToo)
{
    if(!$dh = @opendir($dir))
    {
        return;
    }
    while (false !== ($obj = readdir($dh)))
    {
        if($obj == '.' || $obj == '..')
        {
            continue;
        }

        if (!@unlink($dir . '/' . $obj))
        {
            unlinkRecursive($dir.'/'.$obj, true);
        }
    }

    closedir($dh);

    if ($deleteRootToo)
    {
        @rmdir($dir);
    }

    return;
}

I got it from php.net and it works.

我从php.net得到的，它起作用了。

There is no single function build into PHP that would allow this, you have to write your own with rmdir and unlink.

PHP中没有一个单独的函数允许这样做，您必须使用rmdir和unlink编写自己的函数。

An example (taken from a comment on php.net docs):

一个例子(摘自对php.net文档的评论):

<?
// ensure $dir ends with a slash
function delTree($dir) {
    $files = glob( $dir . '*', GLOB_MARK );
    foreach( $files as $file ){
        if( substr( $file, -1 ) == '/' )
            delTree( $file );
        else
            unlink( $file );
    }
    rmdir( $dir );
}
?>

#5

You will have to delete all the files recursively. There are plenty example functions in the comments of the rmdir manual page:

您将不得不递归地删除所有文件。在rmdir手册页的注释中有很多示例函数:

http://www.php.net/rmdir

You could always cheat and do shell_exec("rm -rf /path/to/folder");

您可以始终作弊并执行shell_exec(“rm -rf /path/to/folder”);
