我正在处理一个包含许多插入字段的页面。如何缩短以下代码?
$title_1 = $_POST['title_1'];
$content_1 = $_POST['content_1'];
$link_1 = $_POST['link_1'];
$img_link_1 = $_POST['img_link_1'];
$title_2 = $_POST['title_2'];
$content_2 = $_POST['content_2'];
$link_2 = $_POST['link_2'];
$img_link_2 = $_POST['img_link_2'];
$title_3 = $_POST['title_3'];
$content_3 = $_POST['content_3'];
$link_3 = $_POST['link_3'];
$img_link_3 = $_POST['img_link_3'];
