How can non-programmers navigate through PHP code updates and modernization efforts for websites that are primarily maintained as hobbies rather than for commercial purposes?

Non-programmers can navigate through PHP code updates and modernization efforts by seeking help from online resources, forums, or tutorials. They can also consider hiring a freelance developer to assist with the updates. Additionally, using version control systems like Git can help track changes and revert back to previous versions if needed.

<?php

// Before update
$old_result = mysql_query($query);

// After update
$new_result = mysqli_query($connection, $query);
