我想用PHP來顯示列的總和，但它給我0

Question

<?php 
    $con=mysqli_connect("localhost","root","root","test"); 
    // Check connection 
    if (mysqli_connect_errno()) 
    { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 

    $results = mysqli_query($con,"SELECT SUM(jumlah) AS jumlah_sum FROM finance_income"); 
    echo '<center>'; 

while($rows = mysqli_fetch_array($results)); 
{ 
    echo "<p>" . "Rp " . number_format($rows['jumlah_sum']) . "</p>"; 
} 
echo "</center>"; 

mysqli_close($con); 



?> 

我已經改變了一些代碼，但是當我打開這個PHP文件，它不加我的所有號碼，它只是在網上有人打印0知道是什麼發生？

您正在使用msqli_connect進行連接，但使用mysql_query進行查詢。 不要混合這兩個庫。使用mysqli_query而不是mysql_query。 mysql_fetch_array也是如此。使用mysqli_fetch_array

<?php 
    $con=mysqli_connect("localhost","root","root","test"); 
    // Check connection 
    if (mysqli_connect_errno()) 
    { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 

    $results = mysqli_query($con,"SELECT SUM(jumlah) AS jumlah_sum FROM finance_income"); 
    echo '<center>'; 

while($rows = mysqli_fetch_array($results)); 
{ 
    echo "<p>" . "Rp " . number_format($rows['jumlah_sum']) . "</p>"; 
} 
echo "</center>"; 

mysqli_close($con);
