How do I check if a directory exists via PHP?

Question

I want to create a directory if it does'nt exist. Is using `is_dir` enough for that purpose? if (!is_dir($dir)) { mkdir($dir);    } Or should I combine `is_dir` with `file_exists`? if (!file_exists($dir) && !is_dir($dir)) { mkdir($dir);    }

Answer 1

$docPath = "home/someDirectory";

if(is_dir($docPath) == false){

mkdir($docPath, 0777, true);
