How do I check if a directory exists? “is_dir”, “file_exists” or both?

Question

I want to create a directory if it does\'nt exist already.

Is using is_dir enough for that purpose?

if ( !is_dir( $dir ) ) {
    mkdir(

I had the same doubt, but see the PHP docu:

https://www.php.net/manual/en/function.file-exists.php

https://www.php.net/manual/en/function.is-dir.php

You will see that is_dir() has both properties.

Return Values is_dir Returns TRUE if the filename exists and is a directory, FALSE otherwise.
