What are the best practices for setting the include path in PHP to avoid file inclusion errors?

When setting the include path in PHP, it is best practice to use absolute paths to avoid file inclusion errors. This ensures that PHP can locate and include the files correctly regardless of the current working directory. By setting the include path using the `set_include_path()` function with absolute paths, you can prevent potential issues with file inclusion errors.

// Set the include path with absolute paths
set_include_path(get_include_path() . PATH_SEPARATOR . '/absolute/path/to/includes');
