php - 从具有 1 个公共(public)列的 2 个表中获取数据

Question

我想从两个具有共同 user_id 的传出表中获取记录。但我能拿到。下面给出了情况和预期结果。

table->users

id        name         email           phone        city            users_id
1         abc        abc@xyz.om      9899989989      pqr              BMP-1
2         ijk        ijk@xyz.om      9899989988      jkl              BMP-2



table->requirement

id        label_name      label_value    users_id       requirement_id    date 
103         budget         5000           BMP-1            4            11.03.16
104       specialist      dentist         BMP-1            4            11.03.16
105       treatment       clinic          BMP-1            4            11.03.16
106       expertise       criminal        BMP-2            5            10.03.16
107       charges          5100           BMP-2            5            10.03.16          

预期结果:- 它应该在 while { }

中

到目前为止我已经尝试过:-

<div class="table-responsive">

    "SELECT * FROM users AS u RIGHT JOIN  requirement AS r ON
      u.users_id=r.users_id");
while($data=mysql_fetch_assoc($sql)){
    ?>
    <!--loop start-->

            </div>
        </td>
    </tr>
<?php } ?>
<!--loop close-->
</tbody>
</table>
</div>

请建议我应该为此做什么。

试试这个解决方案。它有点长，但它会解决你的问题。

    $query = mysql_query("SELECT u.`users_id`, u.`name`, u.`email`, u.`phone`, re.`label_name`, re.`label_value`, re.`requirement_id`, re.`date` FROM users2 u INNER JOIN requirement re ON u.`users_id`=re.`users_id` WHERE 1");
$resultArr = array(); //to store query result
while($row=mysql_fetch_assoc($query))
{
    $resultArr[] = $row;
}
//print_r($resultArr);
?>
<table class="table table-hover">
<tbody>
<?php
$tempUserID = "";
$tempEmail = "";
$tempPhone = "";
$tempReqID = 0; 
for($i=0;$i<count($resultArr);$i++)
{
    //if user id is blank, assign temporary values we need only for one time.
    if($tempUserID=="")
    {
        $tempUserID = $resultArr[$i]['users_id'];
        $tempEmail = $resultArr[$i]['email'];
        $tempPhone = $resultArr[$i]['phone'];
