Question

所以我试图从我拥有的数据库中显示一个数组。当我运行脚本脚本时，我收到内部服务器错误。现在我不确定这是否与我的配置脚本有关，或者我是否正在通过我的数组正常循环。

include 'config.php';

$conn = name2;
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT Feild FROM Season 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Feild " . $row["Feild"]. " "<br>";
    }
} else {
    echo "0 results";
}

Answer 1

您用于显示结果的语法不正确，请替换：

echo "Feild " . $row["Feild"]. " "<br>";

使用：

echo 'Feild '.$row["Feild"].'<br>';

Answer 2

您尚未正确终止字符串。

替换

echo "Feild " . $row["Feild"]. " "<br>";

使用

echo "Feild " . $row["Feild"]. "<br>";

如果您启用了错误，则会收到错误，说明行号。

Answer 3

我们需要知道您选择哪一列，＆＃34; SELECT Feild FROM Season 1 ＆＃34;不是有效的。它应该是＆＃34; SELECT Feild FROM Season WHERE column =＆＃39; 1＆＃39; ＆＃34;

考虑到这一点，这可以让您更接近解决方案：

include 'config.php';

$conn = name2;
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT Feild FROM Season 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Feild ". $row["Feild"] ."<br>";
    }
} else {
    echo "0 results";
}

Answer 4

使用正确的语法

 echo "Feild ".$row['Feild']."<br>";

尝试显示我的阵列时出错？
