PHP("PHP: Hypertext Preprocessor",超文本预处理器的字母缩写)是一种被广泛应用的开放源代码的多用途脚本语言,它可嵌入到 HTML 中,尤其适合 WEB 开发。
<html> <head> <title>Example</title> </head> <body> <? php echo "Hi, I'm a PHP script!"; ?> </body> </html> |
1. <?php echo("if you want to serve XHTML or XML documents, do like this\n"); ?> 2. <? echo ("this is the simplest, an SGML processing instruction\n"); ?> <?= expression ?> This is a shortcut for "<? echo expression ?>" ?> 3. <script language="php" runat=server> echo ("some editors (like FrontPage) don't like processing instructions"); </script> 4. <% echo ("You may optionally use ASP-style tags"); %> <%=$variable; %> |
