为什么我无法使用 php 创建目录？
我有一个用户可以上传图像的表单。我有另一个已经可以使用的页面，然后创建一个目录并将图像放入其中。由于某种原因，当我将相同的代码复制到当前页面时，它会出现以下错误：
警告：mkdir() [function.mkdir]：否 这样的文件或目录 /home5/ideapale/public_html/amatorders_final/user_char_upload.php 第251行
这是它所引用的代码：
if (!file_exists("../upload/" . $order_id . '_' . $row['last_name'])) { //Checks if the directory already exists
mkdir("../upload/" . $order_id . '_' . $row['last_name'], 0755); //Creates a new directory with the order_id and Customer last name
}
我尝试回显所有这些变量，所以我知道它们有效。
对我来说这似乎非常简单，所以我不确定为什么 mkdir 函数在此页面上对我不起作用。有人有什么想法吗？
I have a form where users can upload an image. I have another page which already works that then creates a directory and places the image in it. For some reason, when I copy that same code to my current page, it gives me the following error:
Warning: mkdir() [function.mkdir]: No
such file or directory in
/home5/ideapale/public_html/amatorders_final/user_char_upload.php
on line 251
Here is the code it is referring to:
if (!file_exists("../upload/" . $order_id . '_' . $row['last_name'])) { //Checks if the directory already exists
mkdir("../upload/" . $order_id . '_' . $row['last_name'], 0755); //Creates a new directory with the order_id and Customer last name
}
I tried echoing out all those variables, so I know they work.
It seems pretty straighforward to me, so i'm not sure why the mkdir function isn't working for me on this page. Any ideas anyone?

使用
mkdir和两个参数，按顺序要创建目录a/b/c，目录a/b必须存在。如果您希望在尝试创建
a/b/c时创建a/b，则需要将true作为第三个参数传递（称为递归;-)）到mkdir。If you `upload` directory already exists, then, you need to make sure that `../upload/` is actually what you think.
此
../upload/相对于当前执行目录（不一定与包含脚本的目录相同！），You might want to try using this :
以检查该目录是否为你的想法 - 它将显示其完整路径（如果存在）；如果没有，则为 false。
Using
mkdirwith two parameters, in order to create the directorya/b/c, the directorya/bmust exist.If you want
a/bto be created when you try to createa/b/c, you need to passtrueas a third parameter (the one calledrecursive;-) ) tomkdir.If you `upload` directory already exists, then, you need to make sure that `../upload/` is actually what you think.
This
../upload/is relative to the current directory of execution (which is not necessarily the same as the one that contains your script !)You might want to try using this :
to check if that directory is what you think -- it'll display its full path if it exists ; or false if it doesn't.
即 move_upload_file($arg);
如果你在 $arg 中给出了错误的路径，它将显示你所说的错误消息。
i.e move_upload_file($arg);
If u give wrong path in $arg,it will show the error msg as u said.
