Question

我正在显示一个问题及其选项。我想使用限制查询。

但我收到了错误。如果我在$query字符串中使用任何其他查询，我没有收到任何错误。

<?php 

$dbc = mysqli_connect('localhost','root','1234','myown')
or die('unable to connect');

// $query = "Select * from question";
// $result = mysqli_query($dbc,$query);
// $num_rows = mysqli_num_rows($result);

$range = rand(0,6); 
echo $range;
$query = "select * from question where limit 1,1";

$result = mysqli_query($dbc,$query)
or die("Error.\n");           
$row = mysqli_fetch_array($result);

?>

<!DOCTYPE html>
<html>
    <head>
        <title></title>
    </head>
    <body>
        <h3> <?php echo $row['sawal']; ?></h3>

        <form method = "POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
            <input type="radio"  name=" answer" value="A" ><?php echo $row['A']; ?><br>
            <input type="radio"  name=" answer" value="B" ><?php echo $row['B']; ?><br>
            <input type="radio"  name=" answer" value="C" ><?php echo $row['C']; ?><br>
            <input type="radio"  name=" answer" value="D" ><?php echo $row['D']; ?><br>

            <input type="submit" name="submit" value="ANSWER"/>
        </form>
    </body>
</html>
<?php
mysqli_close($dbc);
?>

我怎样才能克服它？

Answer 1

$query = "select * from question limit 1,1";

Answer 2

你从1开始你的LIMIT并结束到1 ..因为你得到错误.. 试试这个

“你的查询”（不要在这里使用where语句）LIMIT 0,1;

使用限制时出错？
