How PHP uses mkdir to create a multi-level directory,

The example in this article describes how PHP uses mkdir to create a multi-level directory. Share it with everyone for your reference, the details are as follows:

Using mkdir() in PHP can create multi-level directories. Compared with the previous level-by-level creation, this function is very easy to use.

The following is the function introduction in the PHP manual:
Copy code The code is as follows: bool mkdir ( string $pathname [, int $mode = 0777 [, bool $recursive = false [, resource $context ]]] )
The return value is of bool type.

The first parameter: required, represents the path of the multi-level directory to be created;

The second parameter: Set the permissions of the directory, the default is 0777, which means the maximum possible access rights;

The third parameter: true means allowing the creation of multi-level directories.

Note: You can create a Chinese directory Copy the code The code is as follows: mkdir(iconv("utf-8", "gbk", $path),0777,true); required Use iconv to transcode

The complete sample code is as follows:

<&#63;php
  header("Content-type:text/html;charset=utf-8");
  //要创建的多级目录
  $path="dai/php/php学习";
  //判断目录存在否，存在给出提示，不存在则创建目录
  if (is_dir($path)){ 
    echo "对不起！目录 " . $path . " 已经存在！";
  }else{
    //第三个参数是“true”表示能创建多级目录，iconv防止中文目录乱码
    $res=mkdir(iconv("UTF-8", "GBK", $path),0777,true); 
    if ($res){
      echo "目录 $path 创建成功";
    }else{
      echo "目录 $path 创建失败";
    }
  }
