我有一个快速的问题：

我有这段代码，一切正常，但我需要以不同的方式打印它，我尝试了一些方法，但问题是，我没有收到任何错误，但结果不正确方法，

我要打印的代码是这样的：

<ul class='star-rating' id="star-rating-<?php echo $star['id'];?>">
<?php /* getRating($id) is to generate current rating */?>
  <li class="current-rating" id="current-rating-<?php echo $star['id'];?>" style="width:<?php echo getRating($star['id'])?>%"><!-- will show current rating --></li>
  <?php 
  /* we need to generate 'id' for star rating.. this 'id' will identify which data to execute  */
  /* we will pass it in ajax later */
  ?>
  <span class="ratelinks" id="<?php echo $star['id'];?>">
  <li><a href="javascript:void(0)" title="1 star out of 5" class="one-star">1</a></li>
    <li><a href="javascript:void(0)" title="1 star and a half out of 5" class="one-star-half">1.5</a></li>
  <li><a href="javascript:void(0)" title="2 stars out of 5" class="two-stars">2</a></li>
    <li><a href="javascript:void(0)" title="2 star and a half out of 5" class="two-star-half">2.5</a></li>
  <li><a href="javascript:void(0)" title="3 stars out of 5" class="three-stars">3</a></li>
    <li><a href="javascript:void(0)" title="3 star and a half out of 5" class="three-star-half">3.5</a></li>
  <li><a href="javascript:void(0)" title="4 stars out of 5" class="four-stars">4</a></li>
    <li><a href="javascript:void(0)" title="4 star and a half out of 5" class="four-star-half">4.5</a></li>
  <li><a href="javascript:void(0)" title="5 stars out of 5" class="five-stars">5</a></li>
  </span>
</ul>

虽然我正在尝试这个：

echo"<ul class='star-rating' id='star-rating-'". $star['id'].">
 <li class='current-rating' id='current-rating-".  $star['id']." style='width:". getRating($star['id'])."'%></li>";
 echo'<span class="ratelinks" id="'. $star['id'].'">
  <li><a href="javascript:void(0)" title="1 star out of 5" class="one-star">1</a></li>
    <li><a href="javascript:void(0)" title="1 star and a half out of 5" class="one-star-half">1.5</a></li>
  <li><a href="javascript:void(0)" title="2 stars out of 5" class="two-stars">2</a></li>
    <li><a href="javascript:void(0)" title="2 star and a half out of 5" class="two-star-half">2.5</a></li>
  <li><a href="javascript:void(0)" title="3 stars out of 5" class="three-stars">3</a></li>
    <li><a href="javascript:void(0)" title="3 star and a half out of 5" class="three-star-half">3.5</a></li>
  <li><a href="javascript:void(0)" title="4 stars out of 5" class="four-stars">4</a></li>
    <li><a href="javascript:void(0)" title="4 star and a half out of 5" class="four-star-half">4.5</a></li>
  <li><a href="javascript:void(0)" title="5 stars out of 5" class="five-stars">5</a></li>
  </span>
</ul>';

您在 echo 和字符串之间缺少一个空格。您在字符串中也有一些错误。

echo "<ul class='star-rating' id='star-rating-". $star['id']."'>
 <li class='current-rating' id='current-rating-".  $star['id']."' style='width:". getRating($star['id'])."%'></li>";
echo '<span class="ratelinks" id="'. $star['id'].'">
  <li><a href="javascript:void(0)" title="1 star out of 5" class="one-star">1</a></li>
    <li><a href="javascript:void(0)" title="1 star and a half out of 5" class="one-star-half">1.5</a></li>
  <li><a href="javascript:void(0)" title="2 stars out of 5" class="two-stars">2</a></li>
    <li><a href="javascript:void(0)" title="2 star and a half out of 5" class="two-star-half">2.5</a></li>
  <li><a href="javascript:void(0)" title="3 stars out of 5" class="three-stars">3</a></li>
    <li><a href="javascript:void(0)" title="3 star and a half out of 5" class="three-star-half">3.5</a></li>
  <li><a href="javascript:void(0)" title="4 stars out of 5" class="four-stars">4</a></li>
    <li><a href="javascript:void(0)" title="4 star and a half out of 5" class="four-star-half">4.5</a></li>
  <li><a href="javascript:void(0)" title="5 stars out of 5" class="five-stars">5</a></li>
  </span>
</ul>';

我必须说，我很想知道您为什么要进行此更改的原因？我建议用单引号将您的字符串括起来'。这样，您仍然可以使用预期的双引号添加 HTML 属性，"而无需转义它们。

例子：

echo '<ul class="star-rating" id="star-rating=' . $star['id'] . '">
  <li class="current-rating" id="current-rating-' . $star['id'] . '" style="width:' . getRating($star['id']) . '%"></li>';

在处理大量 HTML 时，我总是建议使用heredoc和使用{}来替换变量，即{$star['id']}.

你需要在这个heredoc之前计算你的星级。

echo <<<"EOD"
<ul class='star-rating' id="star-rating-{$star['id']}">
<?php /* getRating($id) is to generate current rating */?>
  <li class="current-rating" id="current-rating-{$star['id']}" style="width:{$star_rating['id']}%"><!-- will show current rating --></li>
  <span class="ratelinks" id="<?php echo $star['id'];?>">
  <li><a href="javascript:void(0)" title="1 star out of 5" class="one-star">1</a></li>
    <li><a href="javascript:void(0)" title="1 star and a half out of 5" class="one-star-half">1.5</a></li>
  <li><a href="javascript:void(0)" title="2 stars out of 5" class="two-stars">2</a></li>
    <li><a href="javascript:void(0)" title="2 star and a half out of 5" class="two-star-half">2.5</a></li>
  <li><a href="javascript:void(0)" title="3 stars out of 5" class="three-stars">3</a></li>
    <li><a href="javascript:void(0)" title="3 star and a half out of 5" class="three-star-half">3.5</a></li>
  <li><a href="javascript:void(0)" title="4 stars out of 5" class="four-stars">4</a></li>
    <li><a href="javascript:void(0)" title="4 star and a half out of 5" class="four-star-half">4.5</a></li>
  <li><a href="javascript:void(0)" title="5 stars out of 5" class="five-stars">5</a></li>
  </span>
</ul>
