将MySQL数据加载到相应的PHP变量中

我为我做了这项工作,但我确信有更好的方法来完成这项工作。但是,我已经搜索了很多个小时而没有找到我想要做的事情的确切答案。基本上从URL获取变量usrID,我需要在MySQL中搜索相应的信息给这个用户。后来我想使用我页面上的不同字段(更好的网站)来个性化体验。

<?php
$servername = "localhost";
$username = "authorized-user";
$password = "secret";
$dbname = "agentDB";
$usrID = "001";


$conn = mysqli_connect($servername, $username, $password, $dbname);

if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}

$sql = "SELECT * FROM agentInfo WHERE usrID = '$usrID'";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {

while($row = mysqli_fetch_assoc($result)) {
    $Lname = $row["Lname"];
    $Fname = $row["Fname"];
    $tl = $row["tl"];
        }
} 
mysqli_close($conn);
?>

here is the body<br>
My name is: <?php echo $Fname; ?> <?php echo $Lname; ?><?php echo $tl; ?>

你可以创建一个变量来存储一个全名,然后像这样“tl”:

$user_info = $Lname . ", " . $Fname . ": " . $tl;

然后:

<?php echo $user_info; ?>

无论您何时需要该信息。

如果要最小化分配的变量数量,可以将其包装在函数中并返回所需的数据字段:

function fetchUserData(userData) {
    $conn = mysqli_connect($servername, $username, $password, $dbname);

    if (!$conn) {
        die("Connection failed: " . mysqli_connect_error());
    }

    $sql = "SELECT * FROM agentInfo WHERE usrID = '$usrID'";
    $result = mysqli_query($conn, $sql);

    if (mysqli_num_rows($result) > 0) {

        while($row = mysqli_fetch_assoc($result)) {
            $userData = $row[userData];
        }
    }
    return $userData;
} 
mysqli_close($conn);

您可以像这样获取指定的数据:

<?php echo fetchUserData("Fname"); ?>
