$ Dir = "load ";
Mkdir ("load", 0777 );
$ Opendir = is_dir ($ dir );
If (! $ Opendir)
{
Echo "exists ";
}
Else
{
Echo "does not exist ";
}
?>

What is the problem with the above code? Why does it always show that it does not exist.
If you change to another directory, the system will prompt that the path does not exist. Both the front and back slashes have been tried.
Is windows a permission issue?

If judgment is the opposite...

Do you have mkdir ("load", 0777);, $ opendir is true, so it enters else. Are you sure you have any questions?

Thanks to the two great gods, you did not need to pay attention to it...
