这样写是什么意思?

上面的代码是在html文件中写的,我想请问 


这段代码上面一个EOT上面应有对应的开头部分。下面一行if($ifmagic && $read[lou]==0){print ------解决方案--------------------
你的文件是否有include或者require其他文件?
------解决方案--------------------
Heredoc技术,在正规的PHP文档中和技术书籍中一般没有详细讲述,只是提到了这是一种Perl风格的字符串输出技术。但是现在的一些论坛程序,和部分文章系统,都巧妙的使用heredoc技术,来部分的实现了界面与代码的准分离。 

在PHP的文档中,只是提到了echo可以使用如下命令输出多行字符串(而且其中的变量被自动替换):
PHP代码
复制代码 代码如下:

echo This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;

上面的END结束符可以自己规定,使用了“EOT”来结束。但是需要注意的是,这个END必须是在一行的开头才能有效,这其实是Heredoc技术的一个局限性(因为heredoc可以自定义结束符,所以引入了这个问题)。
为了让heredoc的内容能被DreamWeaver这样的编辑器正确识别,以实现“所见即所得的”的网页设计,需要在heredoc中增加注释,示例文件如下: 

PHP代码
复制代码 代码如下:
