PHP-获取与api一起使用的单元格的值。
PHP-获取与api一起使用的单元格的值。
提问于 2014-03-13 19:27:02
对不起，如果这是个愚蠢的问题，我在PHP是个新手。
首先，我想做的是：
我正在从MYSQL中提取信息，并在页面上显示信息。具体而言，这一点：
while($rowsID = mysql_fetch_assoc($sIDD))
{
echo '<tr>';
foreach($rowsID as $key => $cell){
print '<td>'.$cell.'</td>';
}这很好，并显示了我想要的信息。
从那个牢房里的信息，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 $myarray['response']['players'][0]['avatarmedium'];
print '>'; `这不管用。它不会从单元格中提取实际数字并将其放入$sid中。我在这里不知所措。我在谷歌上搜索了几天，我的大部分代码都是从我在这里找到的部分中提取出来的，所以我甚至不确定我是否在正确的轨道上。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。
完整的代码：
<?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");
$sql = "SELECT Members.PID, Members.ID, Members.Steam_Name, Members.SG_ID\n"

?>我意识到这段代码可能是一场灾难，我计划一旦它开始工作，并更充分地理解我所看到的，我就会清理它。我已经复制并修补了来自许多不同来源的代码，并尝试了自己的代码。别恨我。:-)

有几个问题。首先，也是最重要的，在$rowsID变量有数据之前使用它。
$sid = $rowsID['steamID'];
^-------- You don't assign this a value until 12 lines later, here:
while($rowsID = mysql_fetch_assoc($sIDD))其次，您应该而不是使用mysql_*函数。相反，您可以查看米斯里或PDO，以替代不推荐的mysql函数。
第三，净化您的输入。您正在获取$_GET['id']中的值，并将其直接传递给查询。你好，小鲍比桌子。
解决这些问题应该能让你上路。
有几件事你可能想要考虑改进：
- 如果我正确地阅读了您的查询，您是根据玩家名称查询的，对吗？如果两个人的名字是
Llama，会发生什么？ - 如果您要为每个用户查询蒸汽API，请构建一个由逗号分隔的配置文件ID字符串，然后在进行API调用时将所有这些(最多100个)传递给
steamids变量。这减少了必须往返于Valve服务器的次数。 - 我不知道您的数据库结构，但是这些查询中有几个看起来可以与一些漂亮的SQL结合在一起。如果您知道更复杂的SQL，最好减少对数据库的调用，以提高性能。
