<?php
/**
 * php删除指定的目录
 *
 * @param 
 * @author 编程之家 jb51.cc jb51.cc
 * Delete a file,or a folder and its contents (recursive algorithm)
 * @param       string   $dirname    Directory to delete
 * @return      bool     Returns TRUE on success,FALSE on failure
 */
function rmdirr($dirname)
{
	// Sanity check
	if (!file_exists($dirname)) {
		return false;
	}
	// Simple delete for a file
	if (is_file($dirname) || is_link($dirname)) {
		return unlink($dirname);
	}
	// Loop through the folder
	$dir = dir($dirname);
	while (false !== $entry = $dir->read()) {
		// Skip pointers
		if ($entry == '.' || $entry == '..') {
			continue;
		}
		// Recurse
		rmdirr($dirname . DIRECTORY_SEPARATOR . $entry);
	}
	// Clean up
	$dir->close();
	return rmdir($dirname);
}
