php - 使用 mysqli 和 rand()

Question

尝试创建一个页面，用户可以在其中创建具有基础、一种标记和眼睛颜色的角色。这三个描述都存储在单独的表中，并被随机调用。我想限制它们被调用的次数，以便用户在找到他们喜欢的组合之前无法遍历它们。

<?php
if(!isset($_SESSION['count']))
    $_SESSION['count'] = 0;

if($_SESSION['count'] < 5) {
    $_SESSION['count']++;

    $query = $mysqli->query("SELECT `base` FROM `bases` WHERE `type` = 'Starter' ORDER BY rand()");
    while($info = $query->fetch_assoc()) {
        $_SESSION['refreshresultbase'] = $info['base']; 
    }

    $querymark = $mysqli->query("SELECT `marking` FROM `markings` WHERE `type` = 'Starter' ORDER BY rand()");
    while($infomark = $querymark->fetch_assoc()) {
        $_SESSION['refreshresultmarking'] = $infomark['marking']; 
    }

    $query3 = $mysqli->query("SELECT `colour` FROM `eyes` WHERE `type` = 'Starter' ORDER BY rand()");
    while($infoeye = $query3->fetch_assoc()) {
        $_SESSION['refreshresulteyes'] = $infoeye['colour'];  
    }
}
?>

对 mysqli 来说仍然很新，所以如果这是一个简单的错误，我深表歉意。
