Question

我们可以通过在PHP中返回多个值来实现和回显表吗？

阵列：

   $arrayBooking = array(
            "a01"=>array(
                "Amy"=>array(
                    "booking1"=>array(
                        "231"=>array(
                            "date"=>"21/08/2014",
                            "period"=>array(
                                "from"=>1,
                                "to"=>3
                                )
                            )
                        )
                    )
                ),
            "a02"=>array(
                "Peter"=>array(
                    "booking1"=>array(
                        "231"=>array(
                            "date"=>"22/08/2014",
                            "period"=>array(
                                "from"=>2,
                                "to"=>3
                                )
                            )
                        ),
                    "booking2"=>array(
                        "231"=>array(
                            "date2"=>"24/08/2014",
                            "period"=>array(
                                "from"=>2,
                                "to"=>5
                                )
                            )
                        )
                    )
                )
         )

功能：

  function bookingDate($arrayBooking, $userID){

    $date1String="";
    $date2String="";
    foreach($arrayBooking as $key => $value){
        if($key==$userID){
            foreach($value as $id => $val){
                foreach($val as $booking => $array){
                    foreach($array as $room => $detail){
                        //$reverse = array_reverse($array, true);
                        foreach($detail as $time => $date){
                            if($time=="date"){
                                $date1String = $date;                                   
                            }
                            if($time=="date2"){
                                $date2String = $date;                                   
                            }
                        }

                    }                           
                }
            }

        }
        return $date1String, $date2String;
    }

并显示表格：

     $BookingTable = "<table border=1>";
     foreach($arrayBooking as $key => $value){
         $BookingTable .= "<tr>";
              $BookingTable .= "<td align=center>" . bookingDate($arrayBooking, $key) . "</td>";
         $BookingTable .= "<tr>";
     }
     $BookingTable = "<table border=1>";

我试图返回这些值并转换为数组，但无法列出结果。另外我认为数组的逻辑可能不正确，让函数没有正确显示。（显示所有日期并使用ASC排序）

此外，我被认为是“约会”，所以当预订2个房间的用户时，我将“date”更改为“date2”。

如果你得到php错误，在return语句中尝试这样：“解析错误：语法错误，意外'，'在filename.php行＃”

return $date1String."&&".$date2String;

从多维数组返回多个值
