How can relative path issues be resolved when uploading PHP scripts and templates to a server?
Relative path issues can be resolved by using the `__DIR__` magic constant in PHP to get the absolute path of the current directory and then constructing the relative path from there. By using `__DIR__`, you can ensure that the paths are always correct regardless of where the script is located on the server.
// Example of resolving relative path issues using __DIR__
require_once(__DIR__ . '/includes/config.php');
include(__DIR__ . '/templates/header.php');
