我有一個這樣的 HTML 代碼：<figure id="attachment_83" aria-describedby="caption-attachment-83" style="width: 300px" class="wp-caption alignnone"> <img class="size-medium wp-image-83" src="https://sampleonly.com/wp-content/uploads/2020/01/my-picture-300x169.jpg" alt="" width="300" height="169" srcset="https://sampleonly.com/wp-content/uploads/2020/01/my-picture-300x169.jpg 300w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-1024x576.jpg 1024w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-768x432.jpg 768w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-1536x864.jpg 1536w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-1218x685.jpg 1218w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture.jpg 1920w" sizes="(max-width: 300px) 100vw, 300px" /> <figcaption id="caption-attachment-83" class="wp-caption-text">This is my picture text.</figcaption><figure>我想刪除 id、style、class 等。最終代碼如下：<figure> <img src="https://sampleonly.com/wp-content/uploads/2020/01/my-picture.jpg"/> <figcaption>This is my picture text.</figcaption><figure>有人可以幫我嗎？謝謝你。

這是 preg 替換，您可以使用它來刪除所需屬性以外的屬性。
$html = preg_replace("/(<img\\s)[^>]*(src=\\S+)[^>]*(\\/?>)/i", "$1$2$3", $html);
$html = preg_replace("/(<figure\\s)[^>]*[^>]*(\\/?>)/i", "$1$2$3", $html);
$html = preg_replace("/(<figcaption\\s)[^>]*[^>]*(\\/?>)/i", "$1$2$3", $html);
這會給你輸出
<figure ><img src="https://sampleonly.com/wp-content/uploads/2020/01/my-picture-300x169.jpg"><figcaption >This is my picture text.</figcaption><figure>

您可以使用以下代碼注意：如果您包含 jquery，則僅使用腳本，否則使用下面的 jquery 鏈接
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$('figure,figcaption,img').removeAttr("id style class height width sizes srcset aria-describedby");
</script>
