Question

我正在尝试为汽车租赁公司制作一个自定义汽车时刻表日历，以便在附件文件中显示白色的所有免费日期和红色的繁忙日子。直到现在我成功地用正确的日期和样式颜色绘制日历，但我也希望在td单元格中显示每个预订的客户名称。如果可能的话，合并预订单元

这是我的工作代码，但无论我尝试什么，我都无法在日期数组中传递客户名称，因此我可以以某种方式识别每个客户的预订日。

$datstart2 = "2017-01-01 00:00:00" ;
$datend2 = "2017-01-31 00:00:00" ;
foreach($cars as $cid){
    $query2 = 'select rr.resnumber, DATE_FORMAT( `datestart` , "%Y-%m-%d" ), DATE_FORMAT( `dateend` , "%Y-%m-%d" ), rr.cl_name, rr.totdays from res_cars rc,res_reservations rr where rr.carid="'.$cid.'" and datestart > now() and (datestart BETWEEN "'.$datstart2.'" AND "'.$datend2.'") group by resnumber order by datestart ASC';
    $result2=mysql_query($query2) or die($query2);
    $num_rows2=mysql_num_rows($result2);

    for($j=0;$j<$num_rows2;$j++){
        $row2=mysql_fetch_row($result2);

        $current = strtotime($row2[1]);
        $last = strtotime($row2[2]);
        //here I generate array that contains all busy days between datestart & dateend for each reservation
        while( $current <= $last ){
            $dates1[] = date('Y-m-d', $current);
            $current = strtotime($step, $current);
        }
    }
   //here I generate a new array with all days without reservation for January for the car
    $dates2 array consists all days in the month

    $emptydays=array_diff($dates2,$dates1);

    foreach($dates as $date){
        //here I draw table cell with different styles if the dy is reserved or not
        if(in_array($date,$emptydays)){
            echo '<td class="emptyday">.</td>';
        } else {
           echo '<td class="busyday">X</td>';
        }
    }
}

问题是我希望来自busyday类型的表格单元格看起来像：

echo '<td class="busyday">Customer names here</td>';

但无论我尝试过什么都没有成功。请各位帮帮我，并告诉我打印每个预订的客户名称（cl_name）的正确方法，并使其看起来像：

echo '<td class="busyday">Customer names here</td>';

一种可能的解决方案是将$date数组更改为而不是仅存储日期，您可以为每个日期/ customer_name存储数组：

$dates = array
  (
  array("date"=>"2016-12-10", "customer_name"=>"Customer 1"),
  array("date"=>"2016-12-15", "customer_name"=>"Customer 2"),
  array("date"=>"2016-12-15", "customer_name"=>"Customer 3"),
  array("date"=>"2016-12-20", "customer_name"=>"Customer 4")
  );

然后你可以访问它：

echo $dates[0]["date"].": ".$dates[0]["customer_name"];

例如，在foreach循环中：

foreach($dates as $date){
    if(in_array($date["date"],$emptydays)){
        echo '<td class="emptyday">'.$date["customer_name"].'</td>';
    } else {
       echo '<td class="busyday">'.$date["customer_name"].'</td>';
    }         
 }

还有一个例子，在你的while循环中，你可以这样做：

array_push($dates, array("date"=>date('Y-m-d', $current),
                         "customer_name"=>$row2["cl_name"]));

$dates1[] = $dates;     // or array_push($dates1, $date);

*您在问题中提到了“cl_name”，因此我将其作为列名称，如果没有，请将其替换为正确的名称。
