Create a directory in php

The mkdir() php function can be used to create a directory provided that the necessary file permissions exist.

Example on mkdir():

<?php 
if (file_exists("/temp/test")) {
  print("Test Directory already exists.\n");
} else {
  mkdir("/temp/test");
  print("Test Directory created.\n");
}
?>

Output – first execution

Test Directory created.

If you run this script again, it will print:

Test Directory already exists.
