Question

啊，我写了一个脚本，但我已经忘记了如何获取MySQL记录......所以......我遇到了这个问题

资源ID＃X

$QUERY = "SELECT id FROM WORKING TABLE VARIABLE WHERE username='WORKING USERNAME VARIABLE' and password='WORKING PASSWORD VARIABLE'";
$QUERY1 = mysql_query($QUERY);
$myusername = $QUERY1
echo $myusername;

我知道我必须在这里取。我在互联网上尝试了很多方法。但它们都不起作用。通过我得到NOTHING的结果。请帮忙吗？

没有这个代码......我得到了所有东西，比如密码，电子邮件和用户名（alpha版本）。

Answer 1

试试这个

  $QUERY = "SELECT * FROM WORKING TABLE VARIABLE WHERE username='WORKING USERNAME VARIABLE' and password='WORKING PASSWORD VARIABLE'";
   $QUERY1 = mysql_query($QUERY);
 while($row = mysql_fetch_array($QUERY1))
  {
   $row['username'] =  $myusername;
    echo $row['username'];
  }

Answer 2

试试这个：

$QUERY = "SELECT id FROM WORKING TABLE VARIABLE WHERE username='WORKING USERNAME VARIABLE' 
and password='WORKING PASSWORD VARIABLE' ";
$QUERY1 = mysql_query($QUERY);

while($row = mysql_fetch_array($QUERY1))
  {
  echo $row['id'];//you are selecting id not username
  }

Answer 3

尝试：

echo $myusername[0]['id'];

如果你想实际获取这样的结果，我会使用mysqli_fetch_object。

Answer 4

我已经写了代码来获取每条记录，但是只能获取一条记录
