如果数据库行号小于10，则运行

Question

我只是在我的数据库中'click'行中的数字小于10时才尝试使函数工作。这就是我现在所拥有的：我把回声放在那里只是为了看看条件是否正常工作与否。

<?php
include'connect.php';

$result = mysqli_query($con,"SELECT id, link_name, click  FROM clicks");

while($row = mysqli_fetch_array($result))
{
if ($row['click'] < 10) {
    echo $row['id'] . " " . $row['link_name']. " " .$row['click'];
echo "<br>";
}
}

mysqli_close($con);
?>

Answer 1

试;     

$result = mysqli_query($con,"SELECT id, link_name, click  FROM clicks WHERE click<10");

while($row = mysqli_fetch_array($result))
{
    echo $row['id'] . " " . $row['link_name']. " " .$row['click'];
    echo "<br>";
}

mysqli_close($con);
?>

Answer 2

为什么不在查询中使用where子句？

$result = mysqli_query($con,"SELECT id, link_name, click  FROM clicks
where click <10");
