php和mysql中的post方法

有人知道如何创建提交帖子的方法和下面代码的查询吗？既然它是循环的，有人能给我一个查询的例子吗？我已经创建了查询，但我不知道如何创建提交来找到答案，提交按钮后，它可以显示哪一个是错误的答案和总分用户正确回答它

<?php

如果我没弄错，您应该更改数组的变量：

<?php
include "checklogin.php";

$query = []

$query[] = mysql_query("SELECT * FROM `mcq_questions` WHERE q_id >=0 AND q_id <=3 order by rand() limit 1");
$query[] = mysql_query("SELECT * FROM `mcq_questions` WHERE q_id >=4 AND q_id <=6 order by rand() limit 1");
$query[] = mysql_query("SELECT * FROM `mcq_questions` WHERE q_id >=7 AND q_id <=9 order by rand() limit 1");
$query[] = mysql_query("SELECT * FROM `mcq_questions` WHERE q_id >=10 AND q_id <=12 order by rand() limit 1");
$query[] = mysql_query("SELECT * FROM `mcq_questions` WHERE q_id >=13 AND q_id <=15 order by rand() limit 1");
