Question

为了让我的孩子们开心，我一直在PHP中实施Yellow Car Game以进行长途旅行。其中一个人坐在我的手机上，并在他们看到它们时添加黄色汽车。计数器应该增加每个分数，每周日晚上重置分数并显示上周的胜利者。

上周正确递增，本周再次正常，但周日我注意到所有得分都是0，而我上周的得分根本不是总和。

<?php
    $host = "localhost";
    $un = "username";
    $pw = "password";
    $db = "database";

    $con = mysqli_connect($host, $un, $pw, $db);

    $thisweek = date('Y-m-d', strtotime('Monday this week'));
    //echo $thisweek;
    $lastweek = date('Y-m-d', strtotime('Monday last week'));
    //echo $lastweek;

    $mquery = "SELECT COUNT(who) AS total FROM records WHERE (who = 'Matthew') AND (nowdate >= '$thisweek')";
    $mresult = mysqli_query($con, $mquery);
    $mdata = mysqli_fetch_assoc($mresult);
    $mcount = $mdata['total'];

    $rquery = "SELECT COUNT(who) AS total FROM records WHERE (who = 'Roisin') AND (nowdate >= '$thisweek')";
    $rresult = mysqli_query($con, $rquery);
    $rdata = mysqli_fetch_assoc($rresult);
    $rcount = $rdata['total'];

    $mlquery = "SELECT COUNT(who) AS total FROM records WHERE (who = 'Matthew') AND (nowdate >= '$lastweek') AND (nowdate < $thisweek)";
    $mlresult = mysqli_query($con, $mlquery);
    $mldata = mysqli_fetch_assoc($mlresult);
    $mlcount = $mldata['total'];

    $rlquery = "SELECT COUNT(who) AS total FROM records WHERE (who = 'Roisin') AND (nowdate >= '$lastweek') AND (nowdate < $thisweek)";
    $rlresult = mysqli_query($con, $rlquery);
    $rldata = mysqli_fetch_assoc($rlresult);
    $rlcount = $rldata['total'];

    if ($mlcount > $rlcount) {
        $lcount = "Matthew";
        $first = $mlcount;
        $second = $rlcount;
    }
    else {
        $lcount = "Roisin";
        $first = $rlcount;
        $second = $mlcount;
    }
?>

数据库很简单;一个记录日期和名称的表。添加查询：

INSERT INTO records (who, nowdate) VALUES ('$who', NOW())

我试着回应1月2日星期日的日期，但它告诉我本周是第9天，上周是第2天，正好是7天。

如果有人可以告知我的代码中的任何错误，那将非常感激。

您需要在以下两个查询中单引号$thisweek ...

 $mlquery = "SELECT COUNT(who) AS total FROM records WHERE (who = 'Matthew') AND (nowdate >= '$lastweek') AND (nowdate < '$thisweek')";
    $mlresult = mysqli_query($con, $mlquery);
    $mldata = mysqli_fetch_assoc($mlresult);
    $mlcount = $mldata['total'];

    $rlquery = "SELECT COUNT(who) AS total FROM records WHERE (who = 'Roisin') AND (nowdate >= '$lastweek') AND (nowdate < '$thisweek')";

星期日“周日星期天”strtotime（）错误
