PHTML的概念以及查看phtml格式文件讲解
概念：
PHTML（有时叫做PHP）网页是一种包含PHP（一种和JavaScript或 Microsoft VBScript类似的语言）脚本的网页和ASP一样，PHP脚本镶嵌在网页的HTML代码之中。在页面被发送给请求的用户之前，网页服务器调用PHP解释程序来解释和执行PHP脚本。含有PHP脚本的网页通常都以“.php”、“.php3”或“.phtml”作为后缀。和ASP一样，PHP可以被认为是一种“动态网页”。
查看phtml格式文件：
让Dreamweaver支持phtml(支持更多的文件类型)
ZendFramework模板默认扩展名是.phtml，用DW打开后默认是使用纯文本编辑，不能高亮显示也不能显示代码提示等。只需简单修改DW的配置文件，即可让DW打开phtml后是使用PHP引擎解析：
找到如下文件：
%Dreamweaver安装目录%
configuration
documenttypes
mmdocumenttypes.xml
将原始内容：
修改为(即在粗体部份加上.phtml)：
保存后重新启动DW即可。
类似情况，也可在 mmdocumenttypes.xml 文件内找到对应解析引擎进行手工修改。
