php - PHP-获取单元格的值以与 api 一起使用

Question

抱歉，如果这是一个愚蠢的问题，我对 PHP 还是很陌生。

所以首先，这就是我想要做的事情：

我正在从 MYSQL 中提取信息并在页面上显示信息。特别是这一点：

while($rowsID = mysql_fetch_assoc($sIDD))
{
echo '<tr>';
foreach($rowsID as $key => $cell){
    print '<td>'.$cell.'</td>';
}

这工作正常并显示我想要的信息。

来自该单元格的信息，我想插入：

$sid = $rowsID['steamID'];
$key = '<yoink>';
$slink =file_get_contents('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=' .        $key . '&steamids=' . $sid . '&format=json');
$myarray = json_decode($slink, true);
print '<img src=';
print $myarray['response']['players'][0]['avatarmedium'];
print '>'; `

这不起作用。它不会从单元格中提取实际数字并将其放入 $sid 中。我在这里不知所措。我在谷歌上搜索了好几天，我的大部分代码都是从我在这里找到的位中提取出来的，所以我什至不确定我是否走在正确的轨道上。我希望我已经清楚地解释了我的问题并提供了足够的信息。谢谢你的帮助。

完整代码：

<?php
$hostname = "";   // eg. mysql.yourdomain.com (unique)
$username = "";   // the username specified when setting-up the database
$password = "";   // the password specified when setting-up the database
$database = "";   // the database name chosen when setting-up the database (unique)

$imgR =  "<td><img src='/images/red-dot2.png".$cell['red-dot2.png']."'></td>";
$imgG =  "<td><img src='/images/green-dot2.png".$cell['green-dot2.png']."'></td>";
setlocale(LC_MONETARY, 'en_US');
// Line 10
$_GET['id'];
$name = $_GET['id'];

$link = mysql_connect($hostname,$username,$password);
mysql_select_db($database) or die("Unable to select database");

我意识到代码可能是一场灾难，我计划在它工作后清理它并更全面地了解我正在查看的内容。我已经从许多不同的来源复制并修补了代码，并尝试了我自己的。不要恨我。:-)

有几个问题。首先，最重要的是，您在$rowsID变量有数据之前就使用了它。

$sid = $rowsID['steamID']; 
        ^-------- You don't assign this a value until 12 lines later, here:

while($rowsID = mysql_fetch_assoc($sIDD))

其次，您不应该使用这些mysql_*功能。而是查看mysqli或PDO作为已弃用的 mysql函数的替代品

第三，清理您的输入。您正在获取值$_GET['id']并将其直接传递给您的查询。你好，小鲍比桌。

解决这些问题应该会让你上路。

您可能需要考虑改进的几件事：

如果我正确阅读了您的查询，那么您是根据玩家姓名进行查询的，对吗？如果两个人有名字会发生什么Llama？
如果您要为每个用户查询 Steam API，请构建一串用逗号分隔的配置文件 ID，然后steamids在您进行 API 调用时将所有这些（最多 100 个）传递给变量。这减少了您必须对 Valve 的服务器进行的往返次数
我不知道您的数据库结构，但其中一些查询看起来可以与一些花哨的 SQL 结合使用。如果您了解更复杂的 SQL，最好减少对数据库的调用次数以提高性能。
