我在用doctype W3C验证这段代码时遇到了困难，据我所知，<!doctype html>是HTML5文档类型。

     <?php 
   echo "<img src='uploads/picture01.jpg?".filemtime ('uploads/picture01.jpg')."' class='img' alt='Bass Clef Photography Demo Picture One'/>";
   echo "<img src='uploads/picture02.jpg?".filemtime ('uploads/picture02.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Two'/>";
   echo "<img src='uploads/picture03.jpg?".filemtime ('uploads/picture03.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Three'/>";
   echo "<img src='uploads/picture04.jpg?".filemtime ('uploads/picture04.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Four'/>";
   echo "<img src='uploads/picture05.jpg?".filemtime ('uploads/picture05.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Five'/>";
   echo "<img src='uploads/picture06.jpg?".filemtime ('uploads/picture06.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Six'/>";
   echo "<img src='uploads/picture07.jpg?".filemtime ('uploads/picture07.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Seven'/>";
   echo "<img src='uploads/picture08.jpg?".filemtime ('uploads/picture08.jpg')."' class='img' alt='Bass Clef Photography Demo Picture Eight'/>";

   ?>

我得到的每一行的错误是；

生成代码，

<img src='uploads/picture01.jpg?1405031988' class='img' alt='Bass Clef Photography Demo Picture One'/>
<img src='uploads/picture02.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Two'/>
<img src='uploads/picture03.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Three'/>
<img src='uploads/picture04.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Four'/>
<img src='uploads/picture05.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Five'/>
<img src='uploads/picture06.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Six'/>
<img src='uploads/picture07.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Seven'/>
<img src='uploads/picture08.jpg?1397567043' class='img' alt='Bass Clef Photography Demo Picture Eight'/>

注意：我将文件时间附加到每个图像中，以停止对图像的浏览器缓存。

在图像名称后面缺少一个关闭的'：

<?php 
   echo "<img src='uploads/picture01.jpg?" .filemtime ('uploads/picture01.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture One'/>";
   echo "<img src='uploads/picture02.jpg?" .filemtime ('uploads/picture02.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Two'/>";
   echo "<img src='uploads/picture03.jpg?" .filemtime ('uploads/picture03.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Three'/>";
   echo "<img src='uploads/picture04.jpg?" .filemtime ('uploads/picture04.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Four'/>";
   echo "<img src='uploads/picture05.jpg?" .filemtime ('uploads/picture05.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Five'/>";
   echo "<img src='uploads/picture06.jpg?" .filemtime ('uploads/picture06.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Six'/>";
   echo "<img src='uploads/picture07.jpg?" .filemtime ('uploads/picture07.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Seven'/>";
   echo "<img src='uploads/picture08.jpg?" .filemtime ('uploads/picture08.jpg') . "' class='img' alt='Bass Clef Photography Demo Picture Eight'/>";

   ?>

编辑:在双引号和单引号周围交换

<?php 
   echo '<img src="uploads/picture01.jpg?' .filemtime ('uploads/picture01.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture One" />';
   echo '<img src="uploads/picture02.jpg?' .filemtime ('uploads/picture02.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Two" />';
   echo '<img src="uploads/picture03.jpg?' .filemtime ('uploads/picture03.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Three" />';
   echo '<img src="uploads/picture04.jpg?' .filemtime ('uploads/picture04.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Four" />';
   echo '<img src="uploads/picture05.jpg?' .filemtime ('uploads/picture05.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Five" />';
   echo '<img src="uploads/picture06.jpg?' .filemtime ('uploads/picture06.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Six" />';
   echo '<img src="uploads/picture07.jpg?' .filemtime ('uploads/picture07.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Seven" />';
   echo '<img src="uploads/picture08.jpg?' .filemtime ('uploads/picture08.jpg') . '" class="img" alt="Bass Clef Photography Demo Picture Eight" />';

   ?>

W3C标记验证服务检查文档是否使用有效的HTML。

您得到了错误，因为您试图验证包含PHP的文档:验证器试图将其解释为。

解决方案:验证生成的文档(在PHP运行之后)。您将看到您的代码片段是有效的HTML5。
