I have been following a tutorial on readdir(), is_dir() etc involved in setting up a small image gallery based on folders and files on my FTP. I was wondering what the $directorys[] = $file; part does specifically?
while( $file= readdir( $dir_handle ) )
{
if( is_dir( $file ) ){
$directorys[] = $file;
}else{
$files[] = $file;
}
}
