mkdir(): Invalid argument

I'm trying to create a folder using mkdir() in a PHP script.
In the location of file.php I have a folder named "details". In that folder I want to create another folder.

I use this code:

mkdir("details/$id", 0777, true);

But I always get this warning:

Warning: mkdir(): Invalid argument in C:\Users\Lenovo\xampp\htdocs\public_html\file.php on line 40

I checked that $id isn't empty by echoing it.

How to create the folder with $id name under details folder?

Solution

  • You can not use your $id inside the string, you have to concatenate it

    mkdir("details/". $id, 0777, true);
OR
mkdir("details/{$id}", 0777, true);
