PHP 3 专题 -- 从HTML中脱离

这儿有三种方法从HTML中脱离，同时加入“PHP代码模式”

Example 5-1. 从HTML中脱离的方法

1. <? echo("this is the simplest, an SGML processing instruction\n"); ?>

2. <?php echo("if you want to serve XML documents, do like this\n"); ?>

3. <script language="php">

echo ("some editors (like FrontPage) don't

like processing instructions");

</script>;

4. <% echo("As of PHP 3.0.4 you may optionally use ASP-style tags"); %>
