/*How to call this in block.tpl.php*/
<div id="block-<?php print $block->custom_classes['block_id']; ?>" class="clear-block block block-<?php print $block->module ?>">

This code goes directly into your template.php file after you remove the open and close PHP tags at the beginning and end.

Then place the call below in your block.tpl.php. Don't forget to flush cache.
