When we want to add multi-level directories to our site, we can use php function mkdir() to achieve this function. Supports creating Chinese directories

mkdir() FunctionCreate a directory. Returns true if successful, false otherwise.

Usage:

mkdir(path,mode,recursive,context)

path Required. Specifies the name of the directory to be created.
mode required. Specify permissions. The default is 0777.

mkdir() attempts to create a new directory specified by path.
The default mode is 0777, which means the greatest possible access.

Example code (supports creating Chinese directories):

<?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";
}
