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 there contents, leaving only the files in the $target directory.

Once i have returned the contents of the folder, i dont 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 cant delete folders which have content inside them, is there anyway around this?

Thanks, Ben.

Answer 1

First off, rmdir() cannot delete a folder with contents. If safe mode is disabled you can use the following.

exec("rm -rf folder/");

Also look at is_dir()/is_file() or even better the PHP SPL.

Answer 2

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
    }
}

Answer 3

$directories = scandir('images');
foreach($directories as $directory){
    if($directory=='.' or $directory=='..' ){
        echo 'dot';
    }else{
            echo $directory .'<br />';
}
}
