我想将每个值数组替换为另一个键生成的数组。

$html='
                    <div class="col-md-4 wow fadeInUp" data-wow-delay="0.0s">
                        <div class="price-item">
                            <div class="price-header">
                                <div class="price-title">
                                    <h2>Basic</h2>
                                </div>
                                <div class="price-prices">
                                    <h2><small>$</small>49<span>/ mo</span></h2>
                                </div>
                            </div>
                            <div class="price-body">
                                <div class="price-description">
                                    <ul>
                                        <li>Personal Trainer</li>
                                        <li>Special Class</li>
                                        <li>Free Tutorials</li>
                                        <li>Group Training</li>
                                    </ul>
                                </div>
                            </div>
                            <div class="price-footer">
                                <div class="price-action">
                                    <a class="btn" href="">Join Now</a>
                                </div>
                            </div>
                        </div>
                    </div>
';

这个HTMLDOM输入是每个解析器想要替换的循环键1,2,3。。。。

$dom = new DOMDocument();
$dom->loadHTML($html);
$nodes = $dom->getElementsByTagName("*");

foreach ($nodes as $key => $node ) {
if(!empty($node->nodeValue))      
if ($node->tagName=='h1' || $node->tagName=='h2' || $node->tagName=='span' || $node->tagName=='small' || $node->tagName=='h3' || $node->tagName=='a' || $node->tagName=='p' || $node->tagName=='li'){

$search[]=$node->nodeValue;
$replace[]='$'.$key.'$';
          }  
  }
str_replace($search, $replace, $html);

输出将是两个阵列相互替换 Basic 进入 $1$ 及 $49/ mo 进入 $2$ ....
