数据不是来自mysql

[英]Data is not coming from mysql

它表明已创建连接。 但是我不知道查询中出了什么问题。 查询之后,我尝试回显某些内容,并且该内容在浏览器中可见。

<html>
    <head>

    </head>
<body>

<?php
$servername = "localhost:8888";
$username = "root";
$password = "";
$dbname = "employees";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}else {
    echo "Connected successfully";
}

$res = mysqli_query($conn,"select * from dept_manager");
echo"dept_manager";
while($row=mysqli_fetch_assoc($res))
{
?>
<table>
    <tr>
        <td><?php echo $row['emp_no'] ?></td>
        <td><?php echo $row['dept_no']?></td>
        <td><?php echo $row['from_date'] ?></td>
        <td><?php echo $row['to_date'] ?></td>  
    </tr>
</table>
<?php
}
?>
</body>
</html>
$sql = "select * from dept_manager";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()){
      // your code here

}

试试这个..

在while循环的地方尝试一下:

<?php
    $res = mysqli_query($conn,"select * from dept_manager");
    echo"dept_manager";
    echo "<table>";
    while($row=mysqli_fetch_assoc($res))
    {
     echo "<tr><td>" . $row['emp_no'] . "</td><td>" . $row['dept_no'] . "</td><td>" . $row['from_date'] . "</td><td>" . $row['to_date'] . "</td></tr>";
    }
echo "</table>";
?>

您已经提到servername:localhost:8888,只需检查一次,删除8888并尝试。

我已经在本地系统中尝试使用您的代码,相同的代码可以正常工作。

只要我输入了我的数据库名称和表名称,它就可以正常工作。

因此,您只需按照我的示例进行一次测试即可。

码:-

<html>
<head>
</head>
<body>

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydashboard";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
else{
echo "Connected successfully";
}

$res = mysqli_query($conn,"select * from content_values");

while($row=mysqli_fetch_assoc($res))
{
?>
<table>
    <tr>
        <td><?php echo $row['name'] ?></td>
    </tr>
</table>
<?php
}
?>
</body>
</html>

输出:-

Connected successfully
