从mysql select查询中求和 [英] Summing the Values from mysql select query

问题描述

大家好，

我想总结一下您可以在下面的代码片段中看到的$ row [''val'']返回的值:

Hello all,

I want to sum up the values returned by the $row[''val''] that you can see in my code snippet below:

/*
this part contains the connection parameters
*/

$query = "SELECT val FROM table";
$result = mysql_query($query);

/*
this makes sure the result contains data
*/

WHILE($row = mysql_fetch_assoc($result)){
      echo $row['val'];
}

预先谢谢您.

Thank you in advance.
