Looping <td> depends on rowCount inside while - php

Question

I need loop td inside while fetch.
td loop depends on rowCount variable from the first query.
<?php include'../db/dbConnect.php';
$_GET['tb'];
$t=$_GET['tb'];
$q=$con->prepare("desc $t");
$q->execute();
$h=$q->rowCount(); ?>
<table>
<tr>
<?php while($r=$q->fetch(PDO::FETCH_NUM)){ ?>
<th><?php echo $r[0];?></th>
<?php } ?>
</tr>
<?php
$q=$con->prepare("select*from $t");
$q->execute();
while($r=$q->fetch(PDO::FETCH_NUM)){
$d=$r[0];
?>
<tr>
<td><?php echo $d;?></td>
</tr>
<?php } ?>
</table>
Above code give result :
col1 col2 col3
12
13
14
But i need the result with :
col1 col2 col3
12 vala x
13 valb y
14 valc z
It must give td depends on rowCount variable.
I tried before to loop td by using while, but this i'm not get the logic.
I appreciate some logic or advice of the question.

Answer 1

You're fetching multiple rows:
$r=$q->fetch(PDO::FETCH_NUM)
But then only displaying the first column:
$d=$r[0];
<tr>
<td><?php echo $d;?></td>
</tr>
Try something like this:
while( $r=$q->fetch(PDO::FETCH_NUM) )
{
?>
<tr>
<?php
foreach( $r as $colIdx => $column )
{
?>
<td><?php echo $column;?></td>
<?php
}
<?
</tr>
<?php
}
NB. Not tested; but you get the idea.
