实例演绎php遍历数组与js遍历数组的区别

php遍历数组

 <h2><? echo '学生简介表单信息' ?></h2>
    <ol>
        <!-- php 模板变量 ：充当前面的花括号{    endforeach充当后面的花括号} -->
        <?php foreach ($names as $name): ?>
            <li style="color:greenyellow">
            <a href=""><? echo $name ?></a>
            </li>
        <?endforeach?>
    </ol>

js遍历数组

<script>
        let preLi = document.querySelector("li").nextElementSibling.nextElementSibling;
        console.log(preLi);
        let names = ["小米 17 小米官网","小赖 14 放弃入门","小黄 12 开始学习"];
        names.forEach(item => console.log(item));
    </script>
