What you are seeing is a warning, not an error. The code that you posted does not look like foreach at all, if you can paste the code that has a foreach close to that line, we might be able to help.
If you did not write the theme, don’t try and fix it unless you know what you are trying to do.
Write the following in your wp-config.php file:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
(change WP_DEBUG to false if you are in production)
That warning won’t show up any longer. Look inside wp-content for a file called debug.log and examine the errors there. If functionality is not affected, I would simply ignore this before changing the code of something you are not familiar with.
