php mysql：加入两个表

Question

我有employeeinfo表和employeeseloan表.. 我使用这个查询：

$result=mysqli_query($con,"select tblemployeeinfo.employeeid, tblemployeeloan.amount from tblemployeeinfo left join tblemployeeloan on tblemployeeinfo.employeeid = tblemployeeloan.employeeid where tblemployeeinfo.employeeid = <employee id for example employee id 1>");

while($row = mysqli_fetch_array($result)){
echo "<br>".$row['employeeid'];
echo "<br>".$row['amount'];
}

结果是

employee id: 1
amount: 1000
employee id: 1
amount: 500
employee id: 1
amount: 100

但我想要的是这样显示：

employee id: 1
amount: 1000
amount: 500
amount: 100

抱歉我的英语不好。 tnx提前

正常黑客攻击可以通过以下代码完成

$i = 0 ;
while($row = mysqli_fetch_array($result)){
    if($i == 0)
        echo "<br>".$row['employeeid'];
    echo "<br>".$row['amount'];
    $i++;
}
