PHP Mysql行值之和

大家好，你们能帮我吗？我不知道如何在我的sql数据库中添加行值的代码

我有这个代码，可以计算我有多少条记录

figure 1. sum all value of money   
    id  date           name     money //sample items only
    1   March 5 2014   matt      50 //records to add
    2   March 5 2014   john      10 //records to add
    3   March 2 2014   matt      50 //records to add

figure 2. sum all value of money when search matt
    id  date           name     money //sample items only
    1   March 5 2014   matt      50 //records to add
    2   March 5 2014   john      10
    3   March 2 2014   matt      50 //records to add

由于我的MySQL服务器在操作系统升级后丢失，请不要信任语法lol。请尝试以下操作：

<input type="text" name="namesearch" size="5"  tabindex="1" />

<input type="submit" name='click' value='Search' />


if(isset($_POST['click'])){


    $name= $_POST['namesearch'];
    $query = "SELECT COUNT(*) AS total FROM table WHERE name='$name'"; 
    $result = mysql_query($query); 
    $values = mysql_fetch_assoc($result); 
    $num_item= $values['total']; 
    echo "Number of Records Found # ".$num_item;

这将为您提供每个名称的行数以及总金额。

将此用作查询

SELECT COUNT(*), SUM(`money`) AS `total_money` FROM `my_table` GROUP BY `name`;

使用此选项查看结果

$query = "SELECT COUNT(*) AS total, SUM(money) AS total_money FROM table WHERE name='$name'"; 

将此用作查询

SELECT COUNT(*), SUM(`money`) AS `total_money` FROM `my_table` GROUP BY `name`;

使用此选项查看结果

$query = "SELECT COUNT(*) AS total, SUM(money) AS total_money FROM table WHERE name='$name'"; 

将此用作查询
