我主要有一个关于mysql的问题。我有以下内容：
mysql_query("INSERT INTO {$game}_ships (location,login_id
) values(
'250','44')");
我想将位置设置为 2 到 300 之间的随机数。
我的表结构包括位置和登录 ID 列，我不需要提及其他列，因为它们是静态的并且不会改变。上面的内容应该使一艘船看起来像是在系统中移动。
location int(4)
有人能帮忙吗？
我不知道如何问这个,所以我只想说.我有以下内容:
<style type="text/css">
div.background
{
width:300px;

background:url(<?php
echo '<img src="img/ships/ship_'.$user_ship['shipclass'].'_tn.jpg" />'
?>) repeat;
border:2px solid black;
}
div.transbox
{
width:200px;
height:100px;
margin:30px 50px;
background-color:#ffffff;
border:1px solid black;

This is some text that is …我有以下代码:
$result = mysql_query("select * from ${db_name}_users limit 1");
while ($row = mysql_fetch_array($result, MYSQL_NUM))
{
if ($player[$ships_killed] == 1)
echo "1";
else if ($player[$ships_killed] == 2)
echo "2";
else if ($player[$ships_killed] == 3)
echo "3";
else if ($player[$ships_killed] == 4)
echo "4";
else if ($player[$ships_killed] == 5)
