Question

我有以下代码。它工作但是因为我将我的服务器更新到最后一个php版本，并且因为不推荐使用mysql_fetch_array，所以代码对我不起作用，我很难找到解决方案。欢迎任何帮助。

我有两列有数量和价格的列。我想总结所有件x价格，以找出我库存的产品总量。

$all_products_sumquery_raw = mysql_query(
    "SELECT SUM(products_quantity * products_price_sorter) AS grand_total
    FROM products WHERE products_quantity > 0"
);

$test1 = mysql_fetch_array($all_products_sumquery_raw);

echo '<h2>Total: <span class="totalUred">' . 
    number_format($test1[0], 2, ',', ' ') . 
    '</span>$.</h2>';

Answer 1

使用mysqli让它再次运行：

$link = mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$query = "SELECT SUM(products_quantity * products_price_sorter) AS grand_total FROM products WHERE products_quantity > '0'";
$all_products_sumquery_raw = mysqli_query($link, $query);

/* associative and numeric array */
$test1 = mysqli_fetch_array($all_products_sumquery_raw, MYSQLI_BOTH);

echo '<h2>Total: <span class="totalUred">' . 
    number_format($test1[0], 2, ',', ' ') . 
    '</span>$.</h2>';
