[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
