大虾帮忙看看看这个代码有什么问题?
运行这个模块时,下面红字部分报错Warning: mkdir() [function.mkdir]: No such file or directory  



  /**
* 函数名称: createDir
* 函数功能: 创建文件夹
* 输入参数:
$root ---------------- 根路径
$type ---------------- 类型
* 函数返回值: 返回值说明
* 其它说明: 说明
*/
function createDir($root,$type)
{
if(!file_exists($root."/".$type))
{
$dir_arr = $root."/".$type;
if(mkdir($dir_arr)&&chmod($dir_arr,0777))
{
Return true;
}
else
{
Return false;
}
}
else
{
Return true;
}
}




------解决方案--------------------

PHP code
if(!file_exists($root."/".$type))  //这里将!去掉{$dir_arr = $root."/".$type;<br><font color="#e78608">------解决方案--------------------</font><br>bool mkdir ( string $pathname [, int $mode = 0777 [, bool $recursive = false [, resource $context ]]] )<br><br>带上mode,带上true,递归创建。 [email protected],检查mkdir返回值。<div class="clear">
                 
              
              
        
            </div>
Copy after login
