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(          


        

Answer 1

This is how I do

if(is_dir("./folder/test"))
{
  echo "Exist";
}else{
  echo "Not exist";
}
