How would one go about deleting all of the directories in a directory tree that have a certain name if the only access to the server available is via FTP?
To clarify, I would like to iterate over a directory tree and delete every directory whose name matches a certain string via FTP. A way to implement this in PHP would be nice - where should I start? Also, if anyone knows of any utilities that would already do this, that would be great as well.
分享Here is a starting point- a function that will scan through an FTP directory and print the name of any directory in the tree which matches the pattern. I have tested it briefly.
function scan_ftp_dir($conn, $dir, $pattern) {
$files = ftp_nlist($conn, $dir);
if (!$files) {
return;
}
foreach ($files as $file) {
//the quickest way i can think of to check if is a directory
if (ftp_size($conn, $file) == -1) {
//get just the directory name
$dirName = substr($file, strrpos($file, '/') + 1);
if (preg_match($pattern, $dirName)) {
echo $file . ' matched pattern';
} else {
//directory didn't match pattern, recurse
scan_ftp_dir($conn, $file, $pattern);
}
}
}
}
Then do something like this
$host = 'localhost';
$user = 'user';
$pass = 'pass';
if (false === ($conn = ftp_connect($host))) {
die ('cannot connect');
}
if (!ftp_login($conn, $user, $pass)) die ('cannot authenticate');
scan_ftp_dir($conn, '.', '/^beginswith/');
Unfortunately you can only delete an empty directory with ftp_rmdir(), but if you look here there is a function called ftp_rmAll() which you could use to remove whole directory structures which you find.
Also I have only tested on Unix the trick of using the fail status returned from ftp_size() as a method of checking if an item returned by ftp_nlist() is a directory.
