I am working on a booth booking system. Customer can choose booth and the day to book.

enter image description here

Each selected check box will store in a booking ID after press button Reserve (etc: 3 checked box = 3 booking ID).

When I display all the booking, it will display all the booth and the day. If I book a same booth for 3 days, it will display separately in 3 rows.
enter image description here

How I want to modify my coding so that I can display same booth and its corresponding days in a single row as show below:
enter image description here

Here is my coding:

<?php 

     include("dbconfig.php");

     $query4 = "SELECT bookingID,eventinfo.eventTitle,boothAlias,testbook.bstatus,date,day, username FROM eventinfo, testbook WHERE username='$user' AND testbook.eventID = eventinfo.eventID order by date desc";
     //$query4="select * from testbook, eventinfo where username= '$user' and testbook.'$event'==eventinfo.'$event' order by eventID asc";

        $result4 = mysql_query($query4);
        while($row=mysql_fetch_array($result4))
        {
        $booth=stripslashes($row["boothAlias"]);
        $day=stripslashes($row["day"]);
        $event= stripslashes($row["eventTitle"]);
        $date=stripslashes($row["date"]);
        $bstatus=stripslashes($row["bstatus"]);

    if ($bstatus==0){

        echo "<tr class='record'>";
        echo "<td class='reg' width='80'>$booth</td>";
        echo "<td class='reg' width='80'>$day</td>";
        echo "<td class='reg' width='180'>$event</td>";
        echo "<td class='reg' width='150'>$date</td>";
        echo "<td class='reg' width='70'><img src='icon_stop.gif'/></td>";
        echo "<td class='reg' width='30'><a id='$row[bookingID]' style='color:#ff0000;' class='delbutton' href='#'><img src='icon_delete.gif' border='0'></a></td></tr>";
    }else{
        echo "<tr class='record'>";
        echo "<td class='reg' width='80'>$booth</td>";
        echo "<td class='reg' width='80'>$day</td>";
        echo "<td class='reg' width='180'>$event</td>";
        echo "<td class='reg' width='150'>$date</td>";
        echo "<td class='reg' width='70'><img src='icon.approve.gif'/></td>";
        echo "<td class='reg' width='30'><a id='$row[bookingID]' style='color:#ff0000;' class='delbutton' href='#'><img src='icon_delete.gif' border='0'></a></td></tr>";
    }

        }
    ?>

    Your query needs a GROUP BY clause, along with the GROUP_CONCAT() aggregate function:

    SELECT 
    bookingID,
    eventinfo.eventTitle,
    boothAlias,
    testbook.bstatus,
    date,
    GROUP_CONCAT(day SEPARATOR ', ') AS day, 
    username 
FROM eventinfo, testbook 
WHERE username='$user' 
    AND testbook.eventID = eventinfo.eventID 
GROUP BY booths, date
ORDER BY date desc

    This is untested, but should do what you want. If you get an incorrect result, change what fields you use in your GROUP BY clause.

    In your query, you’re using an implicit join, which isn’t as good as using an explicit join. Without knowing your table structure, I can’t edit the query into an explicit join, but you should look this up and convert it yourself. It’ll save you many a headache with larger queries.
