一、结合已经创建好的影视示例网页,创建一个命名为pl.php的文件,在文件种创建数组$arr_pl,存放评论里需要展示的数据。

$arr_pl = [
        [
            'name' => 'xiaomi1',
            'time' => '2019-9-23 23:23:23',
            'pl' => '不错',
            'mov_id' => 1
        ],
        [
            'name' => 'xiaomi2',
            'time' => '2019-9-22 22:22:22',
            'pl' => '贼***',
            'mov_id' => 1
        ],
        [       
            'name' => 'xiaomi3',
            'time' => '2019-9-21 21:21:21',
            'pl' => '赵敏好漂亮',
            'mov_id' => 1
        ],
        [
            'name' => 'xiaomi4',
            'time' => '2019-9-20 20:20:20',
            'pl' => '我喜欢赵敏',
            'mov_id' => 2
        ],
        [
            'name' => 'xiaomi5',
            'time' => '2019-9-19 19:19:19',
            'pl' => '贼***',
            'mov_id' => 3
        ],
        [
            'name' => 'xiaomi6',
            'time' => '2019-9-19 18:18:18',
            'pl' => '贼***',
            'mov_id' => 4
        ],
        [
            'name' => 'xiaomi7',
            'time' => '2019-9-17 17:17:17',
            'pl' => '贼***',
            'mov_id' => 5
        ],
        [
            'name' => 'xiaomi8',
            'time' => '2019-9-16 16:16:16',
            'pl' => '贼***',
            'mov_id' => 6
        ],
        [
            'name' => 'xiaomi9',
            'time' => '2019-9-16 16:16:16',
            'pl' => '贼***',
            'mov_id' => 7
        ],
        [
            'name' => 'xiaomi10',
            'time' => '2019-9-16 16:16:16',
            'pl' => '贼***',
            'mov_id' => 8
        ],
        [
            'name' => 'xiaomi11',
            'time' => '2019-9-16 16:16:16',
            'pl' => '贼***',
            'mov_id' => 9
        ],

    ]

二、在pl.php文件编写评论显示循环

<div>
    <h3>最新评论:</h3>
    <?php
    $mov_id = intval($_GET['mov_id']);
    foreach ($arr_pl as $v)
        if ($mov_id === $v['mov_id']) {
            echo '<div>';
            echo $v['name'];
            echo '<br>';
            echo $v['time'];
            echo '<p>'.$v['pl'].'</p>';
        };
    ?>
</div>

三、在detail.php中引用pl.php资源

include __DIR__ .'/pl.php';

总结

将头部,底部等公共部分分割成独立的php文件,使用时引入。用数组替换HTML中的数据内容,用foreach来遍历数组,将所需要的内容输出出来,有效的实现HTML中代码的简化。
