（13）重命名文件夹

① 重命名文件夹通过 rename($oldname,$newname) 实现

② 检测文件夹名是否符合规范

③ 检测当前目录中是否存在同名文件夹名称，如果不存在则重命名成功

index.php：

<?php 
require ‘dir.func.php‘;
require ‘file.func.php‘;
require ‘common.func.php‘;
$path = ‘file‘;
$path = @$_REQUEST[‘path‘]?@$_REQUEST[‘path‘]:$path;
$info = readDirectory($path);
if($info == NULL){
    echo ‘<script>alert("没有文件和目录"); </script>‘;
}
$act = @$_REQUEST[‘act‘];
$filename = @$_REQUEST[‘filename‘];
$dirname = @$_REQUEST[‘dirname‘];
//跳转变量
$redirect = "index.php?path={$path}";
if($act == ‘createFile‘){
    //创建文件
    $mes = createFile($path.‘/‘.$filename);
    alertMes($mes,$redirect);
}else if($act == ‘showContent‘){
//查看文件内容
    $content=file_get_contents($filename);
    //echo "<textarea readonly=‘readonly‘ cols=‘100‘ rows=‘10‘>{$content}</textarea>";
    //高亮显示PHP代码
    //高亮显示字符串中的PHP代码
    if(strlen($content)){
