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

## Class synopsis

RecursiveDirectoryIterator extends FilesystemIterator implements SeekableIterator , RecursiveIterator {
/* Methods */
public __construct ( string `$path` [, int `$flags` = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO ] )
public mixed getChildren ( void )
public string getSubPath ( void )
public string getSubPathname ( void )
public bool hasChildren ([ bool `$allow_links` = false ] )
public string key ( void )
public void next ( void )
public void rewind ( void )
/* Inherits */
public FilesystemIterator::__construct ( string `$path` [, int `$flags` = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO | FilesystemIterator::SKIP_DOTS ] )
public mixed FilesystemIterator::current ( void )
public int FilesystemIterator::getFlags ( void )
public string FilesystemIterator::key ( void )
public void FilesystemIterator::next ( void )
public void FilesystemIterator::rewind ( void )
public void FilesystemIterator::setFlags ([ int `$flags` ] )
}
