How can the dirname() function in PHP potentially lead to issues with directory paths?

The dirname() function in PHP can potentially lead to issues with directory paths if the input path contains symbolic links. This can result in the function returning unexpected or incorrect directory paths. To solve this issue, it is recommended to use the realpath() function to resolve any symbolic links before passing the path to the dirname() function. 

// Example code snippet to fix the issue with directory paths containing symbolic links
$input_path = '/path/to/symlink/dir';
$real_path = realpath($input_path);
$dir_name = dirname($real_path);
echo $dir_name;
