Why do I always get an error after using mkdir? ?

After execution, the file can be created successfully, but an error message is always given Warning: mkdir(): File exists in D:wamp64wwwaaa.php on line 26 I only go back to execute this sentence when $name2 obviously does not exist

<code>if(!is_dir($name2)){
        mkdir(iconv("UTF-8", "GBK", $name2),0777,true);
      }</code>

I just tested it and there is nothing wrong with your code. Please check it or take a look at the logic.

<?php
$name2='dirmk';
if(!is_dir($name2)){
    mkdir(iconv("UTF-8", "GBK", $name2),0777,true);
}
