Drupal's theme system allows you to provide alternate template files by way of theme hook suggestions. In other words, you can override the output of nodes, pages, blocks, and more by providing your own template file and using the correct naming scheme. For more information on that naming scheme I suggest reading this article on Drupal 7 Theme Hook Suggestions.

Preprocessing Fields from a Module in Drupal 7

If you're looking to preprocess a field in Drupal 7, you can use hook_preprocess_HOOK. The first "hook" is the name of your module. The second "HOOK" is the theme hook you want to preprocess (e.g. theme_node, theme_block, theme_link, theme_field). You can fine an exhustive list of the Drupal theme hooks by searching the Drupal API.

Here is a simple example of how to use it with fields.

And by wrapping it in a sprint_f, print_r, and pre tag we can safely output it in a nice format.
