Testing if a directory is empty

[niklang]

Hi there,

My site is utilising directories, it creates and writes to them.
One of my pages prints out a list of directories within a directory and this is working fine but i also wish to print a simple 'No directories found' when the directory is empty.

I thought i would just need to do:

if ($file = readdir($dir_handle) == false) {

etc........

}

but this doesn't work and i dunno why.

So my question boils down to how to test if a directory is empty.

Any help would be greatly appreciated.

Thanks

From the php.net/is_dir page:
here is a function that returns true if the dir is empty or if the dir only contains subdirs.

function is_emptydir($which){
$dh=dir($which);
$emptydir=true;
while ($file=$dh->read()) {
if(substr($file,0,1)==".") continue;
if(!is_dir($which."/".$file)) {
$emptydir=false;
break;
}
}
$dh->close();
return $emptydir;
}

Havent tried it myself, let me know how u get on with it please 😃
