Question

我正在开发members.php页面，虽然我是SQL的新手，但我想知道如何查询并显示从我的用户表中注册的所有用户

到目前为止我的成员页面，我猜它会与第12行和第13行类似？

<?php
    ob_start();
    session_start();
    require_once 'dbconnect.php';

    // if session is not set this will redirect to login page
    if( !isset($_SESSION['user']) ) {
        header("Location: index.php");
        exit;
    }
    // select loggedin users detail
    $res=mysql_query("SELECT * FROM users WHERE userId=".$_SESSION['user']);
    $userRow=mysql_fetch_array($res);
?>

构造一个SELECT查询（类似于您在代码中已有的查询），没有任何WHERE子句，获取结果集并循环遍历以获取行，如下所示：

<div class="row">
    <div class="col-lg-12">
        <?php
            $result_set = mysql_query("SELECT * FROM users");
            while($row=mysql_fetch_array($result_set)){
                // your code
            }
        ?>
    </div>
</div>

旁注：不要使用mysql_*函数，从PHP 5.5开始不推荐使用它们，并且在PHP 7.0中完全删除它们。请改用mysqli或pdo。 And this is why you shouldn't use mysql_* functions。

Mysql显示所有用户注册和php
