Question

期望的结果：在我的数据库table1中循环等量的模态作为ID，同时在这些循环模式中成功循环table2中的图像。

当前结果：循环一个模态期间，同时在一个成功的模态中循环table2中的所有图像。

做什么，怎么做？

表1： Table 1 (comment_imgs)

表2：Table 2 (Uploads)

Answer 1

将内部循环中的结果变量$stmt更改为其他内容，因为您要覆盖要迭代的变量。

$stmt = $DB_con->prepare("SELECT * FROM comment_imgs");
$stmt->execute();


       $stmt = $DB_con->prepare("SELECT * FROM uploads");
       $stmt->execute();
       // the variable result is overwritten
