不知怎的php打破了doctype [英] Somehow php broke doctype
问题描述
我创建了两个线程查看从服务器传送的实际网页内容。
编辑：你会发现RAW和HEX选项卡比TextView更重要。从Raw开始，比较Content-Length标题，然后查看HexView，看看发生了什么变化。
I created two threads here and here about that internet explorer works in quirks mode and that broke the layout. After a bit of investigation I found that somehow php make some mess.
For example If I run the code below as html page on web server IE parse it correctly.I`m using small CMS, so if I divide the code in three parts lets say header main footer (CMS combine them) then IE show quirks mode and the layout is broken. The html output from php file is the same as that below.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<style type="text/css" media="screen">
body{
font: 11px Tahoma, Verdana, Arial, sans-serif;
color: #707070;
background: #8c2727 url('../img/bgr_red.png') repeat-x;
}
a {
color:#bc2828;
text-decoration:none;
font-weight: bold;
outline: none;
}
#wrapper{
position: relative;
width: 960px;
margin: 70px auto;
background-color: #fff;
border: 1px solid red;
}
</style>
</head>
<body>
<div id="wrapper">
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.

</div>
</body>
</html>
I belive that the problem is in CMS. But what could broke the doctype ?
EDIT: Here is screenshot from Fiddler
If a browser is treating the two pages differently, then there's some difference between them, even if it's not immediately apparent when you "View Source".
I recommend using a tool such as Fiddler to look at the actual page content as delivered from the server.
Edit: You'll find that the "RAW" and "HEX" tabs are more important than "TextView". Start with "Raw" and compare the "Content-Length" header, then look at "HexView" to see what has changed.
