PHP using mkdir to create a multilevel directory Getting Started example

Let's introduce the mkdir () function:

mkdir ($path, 0777,true);

First parameter: must, represents the path of the multilevel 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 indicates that a multilevel directory is allowed to be created.

Example code (support for creating Chinese catalogs):

<?php header ("Content-type:text/html;charset=utf-8"); The multilevel directory to be created $path = "dai/php/php learning"; Determine if the directory exists no, there is a hint, does not exist then create directory if (Is_dir ($path)) {    echo "Sorry! Directory ". $path. "Already exists! "; } else{  ///The third parameter is "true" means can create multilevel directory, iconv prevent Chinese directory garbled  $res =mkdir (iconv ("UTF-8", "GBK", $path), 0777,true);   if ($res) {   echo "directory $path created successfully";  } else{   echo "Directory $path creation failed";  }? >
