我已经意识到mysql_query已被弃用。 我需要做些什么来解决这个问题？ 所有这些都是MySQL。

简单的事实是，由于功能已被弃用，我需要重新编写整个网站才能使用。

if (!$_GET['XID']) {
    $mystats = array();
    $s       = array();
    $mystats = mysql_query ("SELECT * FROM `members_personal` WHERE playerid = '{$_SESSION['playerid']}'");
    $s       = mysql_fetch_array($mystats);
    echo '<center><main>Personal stats</main>

正如user3284463建议的那样，mysqli_*函数可以轻松更新旧代码而无需完全重写代码。他们通常会替换z()同行。

那就是说，如果你有时间，我会接受rehmat的建议并学习PDO。

答案 1 :(得分：1)

我建议PDO安全地处理数据库。要从旧代码迁移到PDO，首先要重写这样的数据库连接代码：

$dbhost = '';
$dbname = '';
$dbuser = '';
$dbpass = '';
$pdo = new PDO("mysql:host=".$dbhost.";dbname=".$dbname . ';charset=utf8', $dbuser, $dbpass);

然后重写代码的前几行将使其安全并与最新的PHP兼容：

<?php
    // just rewrite your query
    $query = $pdo->prepare("SELECT * FROM `members_personal` WHERE playerid = ?");
    $query->bindValue(1, {$_SESSION['playerid']}); // bind playerid securely
    $query->execute(); // execute your query
    $s = $query->fetchAll(); // fetch details from database as array
    // use the same code
    echo '<center><main>Personal stats</main>

答案 2 :(得分：1)

你可以这样做：

$sql="SELECT * FROM `members_personal` WHERE playerid = '{$_SESSION['playerid']}'";
$mystats = mysqli_query($connection,$sql);
$row = mysqli_fetch_array($mystats,MYSQLI_ASSOC);
