php - how can i print the mySQL sum() in php

Question

I have this query and i am asking if i can print the result in PHP without saving the result in other table.

SELECT SUM(weekly_fees) FROM scout_cabs

Answer 1

你首先给它一个别名来输出：

SELECT SUM(`weekly_fees`) AS `total` FROM `scout_cabs`

然后你通过mysql将它解析为任何正常请求。

<?php
$sql    = "SELECT SUM(`weekly_fees`) AS `total` FROM `scout_cabs`";
$run    = mysql_query($sql);
$result = mysql_fetch_assoc($run);
echo 'The sum of the query is: ' . number_format($result['total']);

如果您还没有使用 mysqli_，它可能也值得研究，因为 mysql_ 现在已弃用。
