PHP: fopen to create folders
提问by Vivek
I need to know if there is any way to create new folder if the path doesn't exist. When I try to fopen() a path, it says NO such File or Directory existsI tried to open the file using 'w' and 'w+' but it is not able to create new folder. Is there any way to achieve it without using mkdir(). Because I need to extract the directory names alone from the path to mkdir() everytime. Any help is appreciated. Thanks...
如果路径不存在，我需要知道是否有任何方法可以创建新文件夹。当我尝试 fopen() 路径时，它说NO such File or Directory exists我尝试使用“w”和“w+”打开文件，但无法创建新文件夹。有没有办法在不使用 mkdir() 的情况下实现它。因为我每次都需要从 mkdir() 的路径中单独提取目录名称。任何帮助表示赞赏。谢谢...

fopen cannot create directories.
fopen 无法创建目录。
You'll need to use something like:
你需要使用类似的东西：
$filename = '/path/to/some/file.txt';
$dirname = dirname($filename);
if (!is_dir($dirname))
{
mkdir($dirname, 0755, true);
}

fopen doesn't create or open folders, only files. You should check with is_dirfirst if it exists, if not create it. mkdirhas a recursive create option.
fopen 不创建或打开文件夹，只创建文件。您应该is_dir首先检查它是否存在，如果不存在则创建它。mkdir有一个递归创建选项。
if (!is_dir($myDir)) {
mkdir($myDir, 0777, true); // true for recursive create
}
If you are looking for a way to open a dir and read it's content you should look at SPL's DirectoryIterator
如果您正在寻找一种打开目录并阅读其内容的方法，您应该查看 SPL 的DirectoryIterator

you can't use fopen to create folders.
To create a folder you have to use mkdir
您不能使用 fopen 创建文件夹。
要创建文件夹，您必须使用 mkdir
for the operations you have to repeat every time, there is a language feature called "user-defined functions". Least known feature of PHP, as one can say judging by stackoverflow answers.
对于每次都必须重复的操作，有一种称为“用户定义函数”的语言功能。PHP 最不为人所知的特性，正如从 stackoverflow 的答案判断的那样。
