PHP 创建嵌套目录

PHP create nested directories

提问by sunjie

I need help with a function to create a 2 level directory for the following situations:

我需要有关为以下情况创建 2 级目录的函数的帮助：

1. The desired sub-directory exists in the parent directory, do nothing.
2. Parent directory exists, sub-directory does not exist. Create only the sub-directory.
3. Neither parent directory, nor the sub-directory exists, First create parent directory, then sub-directory.
4. If Any of the directory was not created successfully, return FALSE.

1. 所需的子目录存在于父目录中，什么都不做。
2. 父目录存在，子目录不存在。仅创建子目录。
3. 父目录和子目录都不存在，先创建父目录，再创建子目录。
4. 如果任何目录未成功创建，则返回 FALSE。

Thanks for the help.

谢谢您的帮助。

Use the third parameter of mkdir():

使用的第三个参数mkdir()：

recursiveAllows the creation of nested directories specified in the pathname. Defaults to FALSE.

recursive允许创建在路径名中指定的嵌套目录。默认为 FALSE。

$path = '/path/to/folder/with/subdirectory';
mkdir($path, 0777, true);

recursive Allows the creation of nested directories specified in the pathname. but did not work for me!! for that here is what i came up with!! and it work very perfect!!

recursive 允许创建路径名中指定的嵌套目录。但对我不起作用！！因为这就是我想出的！！它工作得非常完美！！

$upPath = "../uploads/RS/2014/BOI/002";   // full path 
$tags = explode('/' ,$upPath);            // explode the full path
$mkDir = "";

    foreach($tags as $folder) {          
        $mkDir = $mkDir . $folder ."/";   // make one directory join one other for the nest directory to make
        echo '"'.$mkDir.'"<br/>';         // this will show the directory created each time
        if(!is_dir($mkDir)) {             // check if directory exist or not
          mkdir($mkDir, 0777);            // if not exist then make the directory
        }
    }

you can try using file_existsto check if a folder exists or not and is_dirto check if it is a folder or not.

您可以尝试使用file_exists来检查文件夹是否存在并is_dir检查它是否是文件夹。

 if(file_exists($dir) && is_dir($dir))

And to create a directory you can use the mkdirfunction

并创建一个目录，您可以使用该mkdir功能

Then the rest of your question is just manipulating this to suit the requirements

然后你的其余问题只是操纵它以满足要求

See mkdir, in particular the $recursiveparameter.

参见mkdir，特别是$recursive参数。

How much i suffered.. and got this script..

我受了多少苦..得到了这个剧本..

function recursive_mkdir($dest, $permissions=0755, $create=true){
    if(!is_dir(dirname($dest))){ recursive_mkdir(dirname($dest), $permissions, $create); }  
    elseif(!is_dir($dest)){ mkdir($dest, $permissions, $create); }
    else{return true;}
}

The function you're looking for is MKDIR. Use the last parameter to recursively create directories. And read the documentation.

您正在寻找的功能是 MKDIR。使用最后一个参数递归创建目录。并阅读文档。

As of PHP 5.0+ mkdirhas a recursive parameter which will create any missing parents.

从 PHP 5.0+ 开始，mkdir有一个递归参数，它将创建任何丢失的父项。

// Desired folder structure
$structure = './depth1/depth2/depth3/';

// To create the nested structure, the $recursive parameter 
// to mkdir() must be specified.

if (!mkdir($structure, 0744, true)) {
    die('Failed to create folders...');
}

Returns TRUE on success or FALSE on failure.
