In PHP, the dirname() function is used to return the directory name of a path. This function takes a string containing a path as its only argument and returns a string with the directory name of the given path.
For example, if you have a file located at /home/USERNAME/test.php, the dirname() function would return /home/USERNAME.
If you are on Windows, the dirname() function will return the drive letter followed by a colon (:) if it is included in the path. For example, if you have a file located at C:/home/USERNAME/test.php, the dirname() function would return C:/home/USERNAME.
The dirname() function can also be used with just a relative path. In this case, it will return the current directory name.

Dirnamefile() is a function in PHP that gets the directory name of a given file.
This function is useful when you need to work with files in different directories and you want to make sure that your code is portable.

echo $dir; // /var/www/html/myfolder
// Get the parent directory
$dir = dirname($dir);
echo $dir; // /var/www/html
