将CSS样式应用于PHP输出

为什么不使用HTML的直接输出
// some preceding PHP code
?>
<p>
<strong>Never:</strong> <span id="nevermsg"><?=$results['Never'].$results['text'] ?></span>
</p>
//前面的一些PHP代码
?>
从不：
<?php
echo "<p><strong>Never:</strong> " . $results['<div id=\"nevermsg\">\'Never\'</div>'] . $results['text'] . "</p><br />";
?>
您的查询很好，是您的HTML非常混乱。尝试替换此：
echo "<p><strong>Never:</strong> ".$results['Never']."".$results['text']."</p><br />";
echo“从不：“$results['Never'..”.$results['text'.”
”；
？>
从不：
您需要在while
循环中更改数组类型。将返回一个访问的标准数组，如$array[0]
而不是$array['my_key']]
，因此请使用
因此，与此相反：
while ($results = mysql_fetch_array($raw_results)) {
echo "<p><strong>Never:</strong> <span id=\"nevermsg\">".$results['Never']."</span></p>"; //Doesn't
}
请参见循环的PHP fiddle示例和动作中的
。由于明显的原因，SQL不能在小提琴中复制。这不可能是有效的PHP<代码>解析错误：语法错误，意外的“从不”（T_字符串），应为“]”echo print\r（$results）键和值。如果你的键不正确，那么很容易从那里调整代码。我做到了。我很好奇你为什么让我回答这个问题。无论哪种方式，它都没有改变“从不”行输出的样式。你可以重新查看我添加的更新链接，但它所做的只是重复结果。现在，它显示了两组结果。您可以查看@webfrogs，它告诉我您不需要第二个键。我把它拿走了。。。仍然不能解释数据的缺乏。您是否进行了echo打印（结果）？这将告诉你你的实际回报。你介意添加那一行吗？我来看看输出。查询很好。我正在返回我想要的结果。我只想要这一行echo“从不：”$results['Never']。“$results['text']。”
返回红色字体的结果。我尝试了，但出现了服务器错误。。。页面甚至无法显示。
