PHP mkdir();不工作 [英] PHP mkdir(); not working

问题描述

我一直在尝试Mkdir函数，该函数在我正在研究的项目中将非常有用.我尝试了最简单的代码，但无法创建所需的文件夹.

I've been trying the function Mkdir that will be usefull in the project i'm working on. I've tried the simplest code possible but I can't get it to create the folder I want.

我尝试更改文件夹权限，但是没有更改(Nor 755或777)，并且代码不断返回失败.

I've tried to changes my folder permissions, but that doesn't change (Nor 755 or 777) and the code keeps returning a fail.

请查看我的代码:

<?php 
if(!mkdir($_SERVER['DOCUMENT_ROOT'].'/uploads/2017', 0777, true))
    {
        echo("echec");
    }
chmod($_SERVER['DOCUMENT_ROOT'].'/uploads/2017', 0777);
?>

父文件夹为"admin"，其权限设置为755.

The parent folder is "admin" and it permissions are set to 755.

您有任何线索为什么这行不通吗?

Do you have any clue why this isn't working ?

我重新制作了它，并且起作用了，不知道问题出在哪里.

EDIT : I remade it and it worked, no clue what the problem was.

推荐答案

代码

mkdir('/2017', 0777, true)

创建文件夹2017是文件系统的根文件夹.

creates folder 2017 is a root folder of a file system.

始终将完整的路径设置为您的文件夹，例如:

Always set ethier full path to your folder, e.g.:

mkdir($_SERVER['DOCUMENT_ROOT'] . '/2017', 0777, true);
// or
mkdir('/var/www/mysite/2017', 0777, true);

或使用.或..定义正确的位置:

Or use . or .. to define proper location:

// folder will be created in a same directory 
// as a script which executes this code
mkdir('./2017', 0777, true);

// folder will be created in a directory up one level
// than a script which executes this code
mkdir('../2017', 0777, true);

因此，在您的情况下，很明显:

So, in your case it is obviously:

mkdir($_SERVER['DOCUMENT_ROOT'] . '/admin/2017', 0777, true);
