PHP loop HTML table for each user - php

Question

I have a PHP loop which draws a table based off a MYSQLi query.
What i would like to do is create this table based on a userid (in my case the column called 'badgeid')
At the moment its creating one table
$sql = "SELECT first_name,last_name,signintime,signouttime FROM `signin_entries` WHERE iscleaner ='YES' AND signindate = curdate()";
$list_visitors_result=mysqli_query($con,$sql);
$count_visitors = mysqli_num_rows($list_visitors_result);
if($count_visitors != 0) {
while($row = mysqli_fetch_array($list_visitors_result)){
$signintime = $row['signintime'];
$signouttime = $row['signouttime'];
$firstname = $row['first_name'];
$lastname = $row['last_name'];
echo " <tr><td>$firstname $lastname</td>
<td>$signintime</td>";
if ($signouttime == ""){
echo "<td>Not Signed Out Yet</td>";
} else {
echo "<td>$signouttime</td>";
}
$timeFirst = strtotime(date("Y/m/d") . " " . $signintime);
$timeSecond = strtotime(date("Y/m/d") ." " . $signouttime);
//below checks if th second time is less than the first time than it must be from the day before so add 24 hours eg (signin time 23:30:00 signout time 07:30:30 would be 08:00:30 difference)
if ($timeSecond < $timeFirst)
{
$timeSecond = $timeSecond + 86400;
}
if ($signouttime == ""){
echo "<td>Cleaner Has Not Signed Out Yet</td>";
} else {
$differenceInSeconds = $timeSecond - $timeFirst;
echo "<td class='rowDataSd'>".converttime($differenceInSeconds)."</td>";
}
echo "</tr>";
}
}
//below function converts the seconds difference into hh:mm:ss format to the nearest second
function converttime($seconds) {
$t = round($seconds);
return sprintf('%02d:%02d:%02d', ($t/3600),($t/60%60), $t%60);
}
echo "<tr><th></th><th></th><th></th><th>Total Time Worked</th><tr><td></td><td></td><td></td><td class='totalCol'>Total:</td></tr>";
?>
</table>
</div>
</div>
</div>
</div>
</div>
</section>
</div>
Which is great but i really need a table per 'badgeid'

You could do it like that:
$sql = "SELECT first_name,last_name,signintime,signouttime FROM `signin_entries` WHERE iscleaner ='YES' AND signindate = curdate() ORDER BY badgeid ASC";
$list_visitors_result=mysqli_query($con, $sql);
$count_visitors = mysqli_num_rows($list_visitors_result);
if ($count_visitors != 0) {
echo '<table>';
$current_badgeid = '';
while ($row = mysqli_fetch_array($list_visitors_result)) {
if ($current_badgeid == '') {
$current_badgeid = $row['badgeid']; //define if empty, for the first table
}
if($row['badgeid'] != $current_badgeid){
echo '</table><table>';
$current_badgeid = $row['badgeid'];
}
$signintime = $row['signintime'];
$signouttime = $row['signouttime'];
$firstname = $row['first_name'];
$lastname = $row['last_name'];
echo " <tr><td>$firstname $lastname</td><td>$signintime</td>";
if ($signouttime == "") {
echo "<td>Not Signed Out Yet</td>";
} else {
echo "<td>$signouttime</td>";
}
$timeFirst = strtotime(date("Y/m/d") . " " . $signintime);
$timeSecond = strtotime(date("Y/m/d") ." " . $signouttime);
//below checks if th second time is less than the first time than it must be from the day before so add 24 hours eg (signin time 23:30:00 signout time 07:30:30 would be 08:00:30 difference)
if ($timeSecond < $timeFirst) {
$timeSecond = $timeSecond + 86400;
}
if ($signouttime == "") {
echo "<td>Cleaner Has Not Signed Out Yet</td>";
} else {
$differenceInSeconds = $timeSecond - $timeFirst;
echo "<td class='rowDataSd'>".converttime($differenceInSeconds)."</td>";
}
echo "</tr>";
}
echo '</table>';
}
First, you add ORDER BY badgeid ASC to your query. Then you open a table before the loop starts, and you define a $current_badgeid var. Each time the badgeid changes, you close and reopen a table.
