This section presents a collection of custom blocks submitted by Drupal users.
You can study how the preinstalled Drupal blocks work by searching the associated module files for the string "_block". All blocks defined in a module begin with hook_block.
Have a look to see what is put into
$blocks["content"]. The login-block, for example, is implemented in the user module's
user_block() function as block 0 ("
case 0:" - this delta is there because the user module defines more that one block).
More examples of PHP code snippets can be found in the page snippets section.
