[wp-hackers] wp_head()

[Eric Mann]

wp_head() defines a the hook used by plug-ins and themes to add information
to the header.  WordPress kicks in a long time before header.php is even
loaded.

When you visit a site, you're visiting the index.php file in the root, which
loads WordPress and processes the query.  Then WordPress loads the index.php
file for your theme and that file calls get_header() which loads header.php.
 You're already a long way down the pipe by now and have access to just
about everything and every function defined by WordPress.

WordPress decides what the current page is before picking the theme.  This
is when WordPress decides whether to call your theme's index.php (general
requests), single.php (individual posts), page.php (pages), etc.
