问题描述

我目前有一个如下图所示的数据库.

I currently have a database like the picture below.

其中有一个查询选择了 number1 等于 1 的行.当使用

Where there is a query that selects the rows with number1 equaling 1. When using

mysql_fetch_assoc()

在 php 中我只得到第一个有没有办法得到第二个?就像通过像

in php I am only given the first is there any way to get the second? Like through a dimesional array like

array['number2'][2] 

或类似的东西

推荐答案

使用重复调用 mysql_fetch_assoc.它记录在 PHP 手册中.

Use repeated calls to mysql_fetch_assoc. It's documented right in the PHP manual.

http://php.net/manual/function.mysql-fetch-assoc.php

// While a row of data exists, put that row in $row as an associative array
// Note: If you're expecting just one row, no need to use a loop
// Note: If you put extract($row); inside the following loop, you'll
//       then create $userid, $fullname, and $userstatus
while ($row = mysql_fetch_assoc($result)) {
    echo $row["userid"];
    echo $row["fullname"];
    echo $row["userstatus"];
}

如果需要，您可以使用它来构建多维数组，以便在脚本的其他部分使用.

If you need to, you can use this to build up a multidimensional array for consumption in other parts of your script.
