php - 从 while 循环填充数组以返回 PHP

Question

嗨，我正在尝试使用“user1”和“score1”等索引填充数组以返回到函数。

我的代码:出现无法识别的变量错误

$query = 'select * from users order by score desc';
$result = mysql_query($query) or die (mysql_error());
$highscore = array();
$count = '0';

while($row = mysql_fetch_array($result))
{
    $count++;         
    $highscore = array('user' . $count => $row['username'], 'score' . $count => $row['score']);
}

return $highscore;

Answer 1

当您想要使用数值时，您应该使用它们。您使用了零的字符串表示形式 ('0')

$count = 0;
$highscore = array();
while($row = mysql_fetch_array($result))
{       
    $count++; 
    $highscore['user' . $count] = $row['username'];
    $highscore['score' . $count] = $row['score'];
}
