The PHP code is inserted way before the if statement is ever considered so it's always going to be there.

<ol>
<li>Server evaluates the page and renders any PHP code</li>
<li>The rendered html, including the contents of ie6.php, is sent to the browser</li>
<li>The browser sees the lte IE 6 conditional and takes action</li>
</ol>

blocks|key|338267|text|PHP将打印，因为这正是您告诉它要做的事情。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|338268|您混淆了哪些代码行由服务器运行，哪些代码行由浏览器解析。|338269|Chrome会忽略像<!--[if+lte+IE+6]>这样的行，因为它们只针对IE浏览器。|338270|entityMap^0|6|I|1A|C|0|0|A|I|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|U|8|@]|D|@]|E|$]]]|K|$]]

PHP will print <code>&lt;!--[if lte IE 6]&gt;</code> then include the "ie6.php" file then print <code>&lt;![endif]--&gt;
</code> because that's exactly what you're telling it to do.

You're confusing which lines of code are run by the server and which are parsed by the browser.

Chrome ignores lines like <code>&lt;!--[if lte IE 6]&gt;</code> because they are targeted for IE browsers only.

blocks|key|338279|text|浏览器是唯一使用条件语句的东西。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|338280|由于PHP是在服务器上运行的，然后将生成的页面发送到浏览器，因此IE条件不起作用。|338281|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Browsers are the only things that use the conditional statements.

Because PHP is ran on the server, and then the resulting page is sent to the browser, the IE conditionals do not work.

blocks|key|338293|text|这段php代码将总是包含在服务器端(不管浏览器是什么)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|338294|据我所知，条件注释在客户端工作，浏览器不必尊重它们(我不记得细节了，但我在某处读到，浏览器可以对HTML注释做任何它想做的事情，甚至完全删除它们，这样放入javascript的人可能会感到惊讶)。|338295|如果你想决定是否包含文件，使用一些浏览器检测：$_SERVER‘’HTTP_USER_AGENT‘或get_browser()将是一个很好的起点。|offset|length|338296|entityMap|0|LINK|mutability|MUTABLE|url|http://php.net/manual/en/function.get-browser.php^0|0|0|1E|D|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

This php code going to be included always, on the server side (regardless of the browser). 

As far as I know conditional comments work on client side and browser doesn't have to respect them (I don't rememeber the details but I read somewhere that browser can do whatever it wants with HTML comments, even cut them out completely so people who put javascript into can be surprised).

If you want to decide whether to include file or not, use some browser detection: $_SERVER['HTTP_USER_AGENT'] or <a href="http://php.net/manual/en/function.get-browser.php" rel="nofollow noreferrer">get_browser()</a> would be a good place to start.

blocks|key|3045928|text|问题是，在ie6.php的html代码中有另一个注释，Chrome不喜欢它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3045929|如下所示：|3045930|<?php+print+'This+is+IE6++';+?>|code-block|syntax|javascript|3045931|似乎Chrome将注释结束标记解释为结束标记，并随后“误读”了条件语句。|3045932|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

The problem was that inside the html code in the ie6.php was another comment and Chrome didn't like it.

Something like this:

<pre><code>&lt;?php print '&lt;p&gt;This is IE6 &lt;!--a comment--&gt; &lt;/p&gt;'; ?&gt;
</code></pre>

It seems Chrome was interpreting the comment closing tag as the end tag and subsequently "misreading" the conditional statement.

blocks|key|1637675|text|我在使用chrome时遇到了类似的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1637676|
+++doIEstuff

<![endif]-->|code-block|syntax|javascript|1637677|条件注释中的注释对于FF和IE来说是可以接受的，但它会让chrome执行条件注释中的代码|1637678|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I had a similar problem with chrome

<pre><code>&lt;!--[if IE]&gt;

 &lt;!-- a comment about my code --&gt;
 doIEstuff

&lt;![endif]--&gt;
</code></pre>

The comment inside the conditional comment was fine for FF and IE but it made chrome execute the code inside the conditional comment

When I use a conditional statement targeting IE6 and below with some PHP code Google Chrome disregards the statement and inserts the code.

Example:

<pre><code>&lt;!--[if lte IE 6]&gt;
&lt;?php require_once("ie6.php"); ?&gt;
&lt;![endif]--&gt;
</code></pre>

It will insert the content of ie6.php in the body anyway.

The code in ie6.php is something like this:

<pre><code>&lt;?php print '&lt;p&gt;This is IE6&lt;/p&gt;'; ?&gt;
</code></pre>
