删除目录中的文件吗? [英] Delete directory with files in it?

问题描述

我想知道，删除其中包含所有文件的目录的最简单方法是什么?

I wonder, what's the easiest way to delete a directory with all its files in it?

我正在使用rmdir(PATH . '/' . $value);删除文件夹，但是，如果其中有文件，我将无法删除它.

I'm using rmdir(PATH . '/' . $value); to delete a folder, however, if there are files inside of it, I simply can't delete it.

推荐答案

现在至少有两个选项.

1. 在删除文件夹之前，删除其所有文件和文件夹(这意味着递归！).这是一个示例:

1. Before deleting the folder, delete all its files and folders (and this means recursion!). Here is an example:

public static function deleteDir($dirPath) {
    if (! is_dir($dirPath)) {
        throw new InvalidArgumentException("$dirPath must be a directory");
    }
    if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
        $dirPath .= '/';
    }
    $files = glob($dirPath . '*', GLOB_MARK);
    foreach ($files as $file) {
        if (is_dir($file)) {
            self::deleteDir($file);
        } else {
            unlink($file);
        }
    }
    rmdir($dirPath);
}

如果您使用的是5.2+，则可以使用RecursiveIterator来实现，而无需自己实现递归:

And if you are using 5.2+ you can use a RecursiveIterator to do it without implementing the recursion yourself:

$dir = 'samples' . DIRECTORY_SEPARATOR . 'sampledirtree';
$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it,
             RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
    if ($file->isDir()){
        rmdir($file->getRealPath());
    } else {
        unlink($file->getRealPath());
    }
}
rmdir($dir);
