Dir是一个小型库，允许对目录执行一些递归操作。

Dir::scan()

获取目录中所有嵌套目录和/或文件。

$files = Dir::scan('my/dir',       // Can be a string path of an array of string paths
    [
        'include' => '*.txt',      // Can be an array of includes
        'exclude' => '*.save.txt', // Can be an array of excludes
        'type'    => 'file'        // Can be an array of types, possible values:
                                   // `'file'`, `'dir'`, `'executable'`, `'link'`, `'readable'`, `'writable'`
        'skipDots'       => true,  // Keeps '.' and '..' directories in result
        'leavesOnly'     => true,  // Keeps only leaves
        'followSymlinks' => true,  // Follows Symlinks
        'recursive'      => true   // Scans recursively,
        'copyHandler'    => function($path, $target) { // The copy handler
            copy($path, $target);
        }
    ]
);

Dir::copy()

递归地将目录及其文件复制到目标文件夹中。

$files = Dir::copy('my/dir',       // A string path of an array of string paths
    'my/destination',              // A destination path (string only)
    [
        'mode'           => 0755,  // Mode used for directory creation
        'childrenOnly'   => false, // Copies the file inside 'my/dir' if `true`, otherwise `dir` will be
                                   // added as the root directory.
        'followSymlinks' => true,  // Follows Symlinks
        'recursive'      => true   // Scans recursively
    ]
);

Dir::remove()

递归地删除目录及其所有内容。

Dir::remove('my/dir',     // Can be a string path of an array of string paths
    [
        'followSymlinks' => false,        // Follows Symlinks
        'recursive'      => true,         // Scans recursively
        'include'        => '*.txt',      // Can be an array of includes
        'exclude'        => '*.save.txt', // Can be an array of excludes
    ]
);

Dir::make()

创建嵌套目录。

$success = Dir::make('my/dir',  // Can be a string path of an array of string paths
    [
        'mode'      => 0755,         // Mode used for directory creation
        'recursive' => true,         // Scans recursively
        'include'   => '*.txt',      // Can be an array of includes
        'exclude'   => '*.save.txt', // Can be an array of excludes
    ]
);

Dir::tempnam()

创建临时目录（类似于tempnam()函数，但用于目录）。

$dir = Dir::tempnam(sys_get_temp_dir(), 'mytmp');
