How to delete a multilevel directory

Yesterday saw a post (chinaasp) asked how to delete the directory, has been able to, but yesterday there was a problem, the original he just deleted his subordinate files after the deletion

directory So if there are several levels there is a problem.

My this can only temporarily live to use, if your directory does not have more than 10 layers of words should be no problem of it ~, but I am not familiar with recursion can only do

deltree ($path); RmDir ($path) To delete this directory can be directly deltree ($path);

function deltree ($pathdir)
{
echo $pathdir;//I use it for debugging

if (Is_empty_dir ($pathdir))//If it is empty
{
RmDir ($pathdir);//delete directly
}
Else
{//otherwise read this directory except for. and. Outside
$d =dir ($pathdir);
while ($a = $d->read ())
{
if (Is_file ($pathdir. ' /'. $a) && ($a! = '. ') && ($a! = ' ... ')) {unlink ($pathdir. ') /'. $a);}
If it's a file, delete it directly.
if (Is_dir ($pathdir. ' /'. $a) && ($a! = '. ') && ($a! = ' ... '))
{//If the directory
if (!is_empty_dir ($pathdir. ' /'. $a))//Is empty
{//If not, call itself, but the original path + his subordinate directory name
deltree ($pathdir. ' /'. $a);
}
if (Is_empty_dir ($pathdir. ' /'. $a))
{//If it is empty, delete it directly
RmDir ($pathdir. ' /'. $a);
}
}
}
$d->close ();
　　　　
echo "must first delete all files in the directory";//I use it for debugging
　　
}

}

function Is_empty_dir ($pathdir)
{//To determine if the directory is empty, my method is not very good, right? Just to see. and. Something else is not empty, PHP has nothing to give

Function?
$d =opendir ($pathdir);
$i = 0;
while ($a =readdir ($d))
{
$i + +;
}
Closedir ($d);
if ($i >2) {return false;}
else return true;
}
