There are four ways of escaping from HTML and entering "PHP code
mode":
Example 5-1. Ways of escaping from HTML 1
2 1. <? echo ("this is the simplest, an SGML processing instruction\n"); ?>
3
4 2. <?php echo("if you want to serve XML documents, do like this\n"); ?>

6 3. <script language="php">
7 echo ("some editors (like FrontPage) don't

11 4. <% echo ("You may optionally use ASP-style tags"); %>

The first way is only available if short tags have been
enabled. This can be done via the short_tags()
function, by enabling the short_open_tag configuration
setting in the PHP config file, or by compiling PHP with the
--enable-short-tags option to configure.
The fourth way is only available if ASP-style tags have been
enabled using the asp_tags
configuration setting.
Note: Support for ASP-style tags was added in 3.0.4.
The closing tag for the block will include the immediately
trailing newline if one is present.
