PHP生成动态WAP页面(转二)

动态|页面

  一、设置WEB服务器

  首先你的 Web服务器要安装好PHP,即能处理PHP脚本程序。其次,为使Web服务器能同时识别和处理PHP、WML、WBMP等文件,Web 服务器的MIME表需添加以下的几种文件类型。

  text/vnd.wap.wml .wml
  image/vnd.wap.wbmp .wbmp
  application/vnd.wap.wmlc .wmlc
  text/vnd.wap.wmls.wmls
  application/vnd.wap.wmlsc .wmlsc

  二、用PHP输出简单动态WAP页面

  下面有一个最简单的PHP生成WAP页面的例子。注意由于需要PHP解释器来解释该程序,并输出WAP页面,因此所有类似程序应以.php为扩展名。

    header(″Content-type: text/vnd.wap.wml″);
  echo (″

″);
  echo date( ″l dS of F Y h:i:s A″ );
  echo (″

″);
  ?>

  该例子在WAP手机模拟器中可以浏览,输出当前日期时间,而在普通的浏览器中无法识别,甚至会被认为是错误下载。这是因为在程序开头就声明了该输出文档为WML类型,该类型只有WAP设备能够识别并解释。值得注意的是,我们常见的HTML语言对规范性要求不严,大多数浏览器能“容忍”其中相当多的编写错误,而WML规范相当严格,一点失误都可能导致无法输出所需页面。

  一旦我们知道了用PHP脚本输出WAP页面的标准过程,我们就能够使用PHP强大的功能配合以WML语言的交互处理以及WML Script的简单脚本,开发出适合我们需要的应用系统了。
