<div class="reviews-summary__stats">
                <div class="reviews-summary">
                    <p class="reviews-title">A</p>
                    <ul class="rating">
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>

                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item "></li>

                    <ul class="rating">
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item "></li>
                    </ul>
                </div>
                <div class="reviews-summary">
                    <p class="reviews-title">C</p>
                    <ul class="rating">
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item rating__rated"></li>
                        <li class="rating__item "></li>
                        <li class="rating__item "></li>
                    </ul>
                </div>
</div>

我想迭代每个 div.reviews-summary ，但我没有进入下一个 p.reviews-title 和 li.rating__item rating__rated 标记，并将li.rating__item rating__rated计为单独的p标记，并显示ul中存在的 li.rating__item rating__rated 的整数值。并检查是否存在A，然后显示A的<{1}}。

li.rating__item rating__rated

我希望像这种类型的输出一样显示的阵（     [overalldata] =＆gt;排列         （             [a] =＆gt; 4
            [b] =＆gt; 5
            [c] =＆gt; 4
        ））

任何有任何想法的机构请帮忙解决。感谢

你的HTML（希望）有些错误。您有三组<p class="reviews-title">C</p>，因此所有项目都是“C”。但是如果用A和B替换它们，可以使用以下代码。

所有这一切都是在li[class=rating__item rating__rated]值的小写版本的索引下存储<p class="reviews-title">个项目的数量......

$final_array=array();
foreach ($obj->find('div[class=reviews-summary]') as $factor)
{
    $item = trim($factor->find('p[class=reviews-title]',0)->plaintext);
    $factor = count($factor->find('li[class=rating__item rating__rated]'));
    if($item == 'A')
    {
        $final_array['overalldata']['a']= $factor;
    }
    if($item == 'B')
    {
        $final_array['overalldata']['b']= $factor;
    }
    if($item == 'C')
    {
        $final_array['overalldata']['c']= $factor;
    }
}
print_r($final_array);

我已将HTML更新为（所以只需更换A和B）......

<div class="reviews-summary__stats">
    <div class="reviews-summary">
        <p class="reviews-title">A</p>
        <ul class="rating">
            <li class="rating__item rating__rated"></li>
            <li class="rating__item rating__rated"></li>
            <li class="rating__item rating__rated"></li>
            <li class="rating__item "></li>
            <li class="rating__item "></li>
        </ul>
    </div>
    <div class="reviews-summary">
        <p class="reviews-title">B</p>
        <ul class="rating">
            <li class="rating__item rating__rated"></li>
            <li class="rating__item rating__rated"></li>
            <li class="rating__item rating__rated"></li>
            <li class="rating__item rating__rated"></li>
            <li class="rating__item "></li>
            <li class="rating__item "></li>
        </ul>
    </div>
    <div class="reviews-summary">
        <p class="reviews-title">C</p>
        <ul class="rating">
            <li class="rating__item rating__rated"></li>
            <li class="rating__item rating__rated"></li>
            <li class="rating__item "></li>
            <li class="rating__item "></li>
        </ul>
    </div>     
</div>

这输出......

Array
(
    [overalldata] => Array
        (
            [a] => 3
            [b] => 4
            [c] => 2
        )

)
