只有在使用php将文件夹上载到远程ftp后，才能从服务器中删除文件夹

函数ftp\u putAll（$conn\u id、$backup、$workpath、$delete）{
$d=dir（$backup）

函数deleteAll（$backup，$remove=false）{
$structure=glob（rtrim（$backup，“/”./*”）；
if（is_数组（$structure））{
foreach（$file形式的结构）{
if（is_dir（$file））
deleteAll（$file，true）；
else if（is_file（$file））
取消链接（$file）；
}
}
如果（$remove）
rmdir（$backup）；
}
