3.3. Formatting

3.3.1. Indenting

All indenting is done with TABS. Before committing any file to CVS, make sure you first replace spaces with tabs and verify the formatting.

3.3.2. PHP Tags

The use of <?php ?> to delimit PHP code is required. Using <? ?> is not valid. This is the most portable way to include PHP code on differing operating systems and webserver setups. Also, XML parsers are confused by the shorthand syntax.
