Question

我有以下查询 -

$query = mysql_query("SELECT * FROM test where admin = 'Yes' order by name = '$_GET[name]' DESC");

while($row = mysql_fetch_array($query))
{
   $id.=$row[id];
}

echo $id;

我想要一个从$ _GET [name]的id开始的id列表但是它返回一个列表，其下面的行的起始名称是？有任何想法吗？

非常感谢。

使用数组
您需要在字符串名称

$query = mysql_query("SELECT * FROM test where admin = 'Yes' order by name = '$_GET[name]' DESC");

$ids = array();
while($row = mysql_fetch_array($query))
{
   $ids[] =$row['id'];
}

// Your IDs are now in an array which is easier to work with
print_r($ids);

仅供参考，you shouldn't use mysql_* functions in new code。它们不再被维护and are officially deprecated。请参阅red box？转而了解prepared statements，并使用PDO或MySQLi - this article将帮助您确定哪个。如果您选择PDO here is a good tutorial。
