Need HELP! "$dir"

I am doing my first PHP script (Following a tutorial in a book)

There are errors on certain lines to do with the Directory path, and help?

These are the errors:

$dir .= $dir1;
$dh = opendir($dir);

Code (markup):

while ($file = readdir($dh)) :

Code (markup):

closedir($dh);

Code (markup):

I think I have to make a directory, if so what name?

I need help!

 

That is the code that is causing the errors. What are the actual error message(s)?

Are you talking about something like this?:

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

PHP:

 

It just says something like "can't find dir" or something, any ideas?

 

Are you sure the directory exists?

Try echo $dir; to confirm the path is correct

 

I created a directory named $dir but I am not sure whether that is what it is meant to be.

 

$dir is a variable that should contain a string. You need to find out what value is stored in $dir by echoing it, as was recommended in a prior comment. Simply do this within your code:

echo $dir;

Then you can create a folder with the same name as what is stored in this variable.
