Question

我有一点问题，我正在尝试制作一个日历，然后我可以根据数据库的结果更改每个框的颜色。目前，我的代码给了我一年中有多少天。有没有一种方法我可以说，例如30个盒装，每个数字上升到30，这样我就可以选择一个特定数量的盒子然后使它变成某种颜色。

  <?php
$number = cal_days_in_month(CAL_GREGORIAN, 2, 2003); 
?>

我已经尝试过使用从数据库中的行中获取信息的方法，这显然是行不通的。亲切的问候千斤顶

我们希望，诚挚地，我们在这里同步。人们可以认为他理解你的意思，但那可能不那么精确。无论如何，您可以使用loop循环$number通过变量for(){}，然后创建具有唯一<div>的框（可能是HTML css classes元素）来帮助你根据自己的意愿style。这是一个可能的想法：

    <?php
        $number     = cal_days_in_month(CAL_GREGORIAN, 2, 2003);

        // LOOP THROUGH THE NUMBER OF MONTHS USING FOR-LOOP AND CREATE
        // THE BOXES THAT YOU DESIRE (WITH CSS-CLASSES, THOUGH)
        $calBoxes   = "";
        for($cue=1; $cue<=$number; $cue++){
            $fmtDay    = date("D", strtotime("2003-2-{$cue}"));
            $calBoxes .= "<div class='date-box date-box-{$cue}'>" . PHP_EOL;
            $calBoxes .= "<span class='date-number date-number-{$cue}'>{$fmtDay}</span>" . PHP_EOL;
            $calBoxes .= "<span class='weekday weekday-{$cue} weekday-" . strtolower($fmtDay) . "'>{$cue}</span>" . PHP_EOL;
            $calBoxes .= "</div>" . PHP_EOL;
        }
        echo $calBoxes; //<== DIRECTLY OUTPUTS THE DATA

        // JUST FOR TESTING PURPOSES; YOU MAY SIMPLY DO A var_dump();
        // var_dump($calBoxes);
        // PRODUCES...          
        <div class='date-box date-box-1'>
            <span class='date-number date-number-1'>Sat</span>
