htmlspecialchars() 是 PHP 中的一个非常有用的函数，用于将特殊字符转换为 HTML 实体。它可以处理以下类型的标签： 文本格式化标签：, , , , , , , , , 等。 链接标签：，其中 href 属性会被转换为 &href=https://www.yisu.com/ask/。 图像标签：，其中 src 属性会被转换为 &src=https://www.yisu.com/ask/。 列表标签：, , , , , 等。 表单标签：, , </code>, <code><button></code> 等。</li> <li>其他标签：<code><table></code>, <code><tr></code>, <code><td></code>, <code><th></code>, <code><caption></code>, <code><thead></code>, <code><tbody></code>, <code><tfoot></code> 等。</li> <li>特殊字符：<code>&</code>, <code><</code>, <code>></code>, <code>"</code>, <code>'</code> 会被转换为对应的 HTML 实体 <code>&</code>, <code><</code>, <code>></code>, <code>"</code>, <code>'</code>。</li> </ol> <p>需要注意的是，<code>htmlspecialchars()</code> 不会处理 JavaScript 标签和属性，也不会处理 CSS 样式。如果需要处理这些标签，可以考虑使用其他库，如 <code>htmlPurifier</code>。</p> </article> <div class="post-copyright">未经允许不得转载 » 本文链接：<a href="https://www.legongju.com/article/4949.html">https://www.legongju.com/article/4949.html</a></div> <div
