Question

如果有100个级别，我应该使用什么语法为用户分配费率。为了避免数百行代码？

function showRank($practice) {

    $ranks = array(     "boy",
                        "student",
                        "master");

    $rank = $ranks[0];

    if ( $practice >= 10 and $practice < 20) {$rank = $ranks[1];}
    else if ($practice >= 20 and $practice < 30) {$rank = $ranks[2];}
    else if ($practice >= 30 and $practice < 40) {$rank = $ranks[3];}

    echo $rank;
}

Answer 1

如果您的进展速度恒定，请执行以下操作：像你一样创建$ranks数组

$ranks = array("boy", "student", "master", .....);

如上所述，将等级进展为10＆＃34;分数＆＃34;每个，然后

$rankId = floor($practice/10);
$rank = $ranks[$rankId];

Answer 2

如果你有10的范围，那么你就可以做到。像这样

  function showRank($practice) {

    $ranks = array(     "boy",
                        "student",
                        "master");

    $rank = $ranks[0];
    foreach ($ranks as $key => $value) {
        $interval = ($key+1)*10;
        if($practice <= $interval)
        {
            $rank = $value;
            break;
        }
    }


    echo $rank;
}
showRank(20);
