The RecursiveDirectoryIterator class

(PHP 5, PHP 7, PHP 8)

简介

The RecursiveDirectoryIterator provides an interface for iterating recursively over filesystem directories.

class RecursiveDirectoryIterator extends FilesystemIterator implements SeekableIterator, RecursiveIterator {

/* 继承的常量 */

const int FilesystemIterator::CURRENT_AS_PATHNAME = 32;

const int FilesystemIterator::CURRENT_AS_FILEINFO = 0;

const int FilesystemIterator::CURRENT_AS_SELF = 16;

const int FilesystemIterator::CURRENT_MODE_MASK = 240;

const int FilesystemIterator::KEY_AS_PATHNAME = 0;

const int FilesystemIterator::KEY_AS_FILENAME = 256;

const int FilesystemIterator::FOLLOW_SYMLINKS = 512;

const int FilesystemIterator::KEY_MODE_MASK = 3840;

const int FilesystemIterator::NEW_CURRENT_AND_KEY = 256;

const int FilesystemIterator::SKIP_DOTS = 4096;

const int FilesystemIterator::UNIX_PATHS = 8192;

/* 方法 */

public __construct(string $directory, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO)

public getSubPath(): string

public getSubPathname(): string

public hasChildren(bool $allowLinks = false): bool

public key(): string

public next(): void

public rewind(): void

RecursiveDirectoryIterator::__construct — Constructs a RecursiveDirectoryIterator
RecursiveDirectoryIterator::getChildren — Returns an iterator for the current entry if it is a directory
RecursiveDirectoryIterator::getSubPath — Get sub path
RecursiveDirectoryIterator::getSubPathname — Get sub path and name
RecursiveDirectoryIterator::hasChildren — Returns whether current entry is a directory and not '.' or '..'
RecursiveDirectoryIterator::key — Return path and filename of current dir entry
RecursiveDirectoryIterator::next — Move to next entry
RecursiveDirectoryIterator::rewind — Rewind dir back to the start
