In this example i am going to explain how to create a directory using PHP and MySQLi .
<!DOCTYPE html>
<html>
<body>
<form action="CreateFolder.php" method="post">
<h2>
Create New Folder
</h2>
<input name="createfolder" type="text">
<input type="submit" value="Create Folder">
</form>
</body>
</html>
CreateFolder.php
<?php
$folder_name=$_POST['createfolder'];
if (!file_exists($output_dir . $folder_name))/* Check folder exists or not */
{
@mkdir($output_dir . $folder_name, 0777);/* Create folder by using mkdir function */
echo "Folder Created";/* Success Message */
}
?>
