这是什么情况,PHP代码和HTML代码混合在一起
代码如下,PHP函数和HTML代码混合在一块,怎么解释?
我刚自学PHP,对这里有些不明白,还望各位不吝赐教。

  public function DisplayStyles()<br />
  { <br />
?>   <br />
  <style><br />
    h1 {<br />
    	color:white; font-size:24pt; text-align:center; <br />
        font-family:arial,sans-serif<br />
    }<br />
    .menu {<br />
    	color:white; font-size:12pt; text-align:center; <br />
        font-family:arial,sans-serif; font-weight:bold<br />
    }<br />
    td {	<br />
    	background:black<br />
    }<br />
    p {<br />
    	color:black; font-size:12pt; text-align:justify; <br />
       	font-family:arial,sans-serif<br />
    }<br />
    p.foot {<br />
    	color:white; font-size:9pt; text-align:center; <br />
        font-family:arial,sans-serif; font-weight:bold<br />
    }<br />
    a:link,a:visited,a:active {<br />
    	color:white<br />
    }<br />
  </style><br />
<?php<br />
  }<br />
<br />
  public function DisplayHeader()<br />
  { <br />
?>   <br />
  <table width="100%" cellpadding="12" <br />
         cellspacing="0" border="0"><br />
  <tr bgcolor ="black"><br />
    <td align ="left"><img  src = "logo.gif" / alt=" 这是什么情况,PHP代码跟HTML代码混合在一起 " ></td><br />
    <td><br />
        <h1 id="TLA-nbsp-Consulting-nbsp-Pty-nbsp-Ltd">TLA Consulting Pty Ltd</h1><br />
    </td><br />
    <td align ="right"><img  src = "logo.gif" / alt=" 这是什么情况,PHP代码跟HTML代码混合在一起 " ></td><br />
  </tr><br />
  </table><br />
<?php<br />
  }
Copy after login

------解决方案--------------------
是的,这是可以的,比如
$a=3;
$b=5;
if($a>$b)
{
?>

Hello


}
else
{
?>

World


}
?>

php语言的技巧,有时候这样做的确很方便,你写多了php之后,就会发现它的妙处了
开始有点不习惯,很正常的
------解决方案--------------------
你可以把
function(){ ?>hello'world<?php }
Copy after login

理解为PHP代码
function(){ echo 'hello\'world'; }
Copy after login

这样做也是为了简洁,想想看,一段字符串里包含很多单双引号,那该有多麻烦啊

------解决方案--------------------
你的疑问是合理的

php 是干什么的?
php 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。

于是在 php 代码中嵌入 HTML 代码的确是显得不伦不类的了
------解决方案--------------------

引用:
引用:是的,这是可以的,比如
  $a=3;
  $b=5;
  if($a>$b)
  {
?>

Hello
  }
  else
  {
