PHP has provided a function to view, create and change the directory or folder. With open this PHP file you can do all mentioned above without need to do manually. Hacker usually use this PHP function to create a PHP SHELL file for uploading to a victim webserver, and with accessing this file they can monitor all directory or all file in the victim webserver. For more detail lets follow steps bellow:

Reactive your webserver
Create a new folder in xampp/htdocs if you use xampp. While you use Linux create it at var/www.
Open the previous folder from your text editor. and create new php file save as index.php
Add HTML element as usual

<html>
<head>
<title>Directory</title>
</head>
<body>
</body>
</html>

Create an input element and a button element

Direktory : <input type="text" name="folder">
 <input type="submit" value="Create">

Open the PHP to write the PHP code

<?php
?>

To view the all directory we can use opendir() function like this

$path=".";
$dir=opendir($path) or die ("can't open directory");

Display all directory using While

while($file=readdir($dir)){
echo "$file ";
}

Add delete button and link it to delete.php to delete the directory

while($file=readdir($dir)){
echo "$file DELETE
";
}

To hide the operation file ( the file is use to manipulate the directory) you can use if function, So the code become like this .

while($file=readdir($dir)){
    if($file=="."||$file==".."|| $file=="index.php"|| $file=="create.php" || $file=="delete.php")
    continue;
    echo "$file    DELETE
";
}

Close the dir

closedir($dir);

Open new file and create a PHP file save as create.php
Get the name folder that you will create from input element in index.php

$dir=$_POST['folder'];

Create the directory using mkdir() function with the permision is 777

mkdir($dir, 777);

reload to index.php

header("location: index.php");

Create new file and save it as delete.php
Get the name folder that you will delete from delete button

$folder=$_GET['dir'];

Delete the directory using rmdir() function

rmdir($folder);

Reload to index.php

header("location: index.php")

Save all file and try to run
Create new directory
You can see the directory just created by you under the input element
To Delete the directory click delete button
Full code you can get bellow:
index.php

<html>
    <head></head>
    <body>
        <form action="create.php" method="POST">
            Direktory : <input type="text" name="folder">
            <input type="submit" value="Create">
        </form>
    </body>
</html>
<?php
$path=".";
$dir=opendir($path) or die ("can't open directory");
while($file=readdir($dir)){
    if($file=="."||$file==".."|| $file=="index.php"|| $file=="create.php" || $file=="delete.php")
    continue;
    echo "$file    DELETE
";
}
closedir($dir);
?>

Create.php

<?php
$dir=$_POST['folder'];
mkdir($dir, 777);
header("location: index.php");
?>

delete.php

<?php
$folder=$_GET['dir'];
rmdir($folder);
header("location: index.php")
?>
