CodeIgniter/PHP : Create directory if does not exist example

Problem :

How to check if a directory exist or not? If not, how to create a directory?

NOTE :

This solution should be applicable for all PHP based frameworks.

Solution :

Use the is_dir() function to test if a directory exist or not. If not, then proceed to mkdir(). For example :

$directoryname = "dirname";

 if (!is_dir('uploads/'.$directory_name)) {
 mkdir('./uploads/' . $date, 0777, TRUE);
 }

The permission setting 0777 is just an example, you can choose to have different setting.
