Using scandir() to find folders in a directory (PHP)

Question

I am using this peice of code:

$target = 'extracted/' . $name[0];   $scan = scandir($target); 

To scan the directory of a folder which is used for zip uploads. I want to be able to find all the folders inside my $target folder so I can delete them and their contents, leaving only the files in the $target directory.

Once I have returned the contents of the folder, I don't know how to differentiate between the folders and the files to be able to delete the folders.

Also, I have been told that the rmdir() function can't delete folders which have content inside them, is there any way around this?

Thanks, Ben.

Answer 1

To determine whether or not you have a folder or file use the functions is_dir() and is_file()

For example:

 $path = 'extracted/' . $name[0]; $results = scandir($path);  foreach ($results as $result) {     if ($result === '.' or $result === '..') continue;      if (is_dir($path . '/' . $result)) {         //code to use if directory     } }

Better to use DirectoryIterator

$path = 'extracted'; // '.' for current foreach (new DirectoryIterator($path) as $file) {     if ($file->isDot()) continue;      if ($file->isDir()) {         print $file->getFilename() . '<br />';     } }
