The date format wil have specail chars like -and :
日期格式将具有特殊字符，例如-和:
I'm not sure about the -but :is not allowed on an map. So you have to delete that char out $date.
我不确定-但:不允许出现在地图上。所以你必须删除那个字符$date。
$date = str_replace( ':', '', $date);
if (!is_dir('uploads/'.$date)) {
mkdir('./uploads/' . $date, 0777, TRUE);
}
or use as elavarasan leesaid use:
或使用elavarasan lee所说的使用：
date('Y-m-d H.i.s')

if you are new to codeigniter and previously in php you used code for making directory like
如果您不熟悉 codeigniter 并且以前在 php 中使用过代码来制作目录，例如
$target_dir="../../media/profile/".date('my')."/";
if(!file_exists($target_dir)){
mkdir($target_dir,0777);
}
then in codeignitor you can use only one dot for outside directory path
然后在 codeignitor 中，您只能使用一个点作为外部目录路径
$target_dir="././media/profile/".date('my')."/";
if(!file_exists($target_dir)){
mkdir($target_dir,0777);
}
this one solved my problem.
这个解决了我的问题。
