?>

正确的方法是什么？

Answer 1

假设您使用PDO对数据库进行了请求。
执行查询后，获取将其用作array。

$req = $bdd->prepare("YOUR QUERY STRING");
$req->execute();

$myarray = $req->fetch()
// The result of the request is saved in this variable as an array
// use $req->fetch(PDO::FETCH_ASSOC) if you want an associative array

echo $myarray['my_value'];
// my_value is your myname

此外，您将函数print()提供给变量$value。您应该为变量赋值并在以下后打印：

$value = $myarray['my_value'] // I continue with the code I wrote above
print($value); // will write your variable

Answer 2

基于w3schools的例子：

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT name FROM YourTable";
$result = $conn->query($sql);

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