PHP MYSQL Associate array and table - php

Question

Here is a code.
This loads all the header part (i.e the header for the table) dynamically from the database.
The below code works fine. But the column is mismatched.
i.e. the first row first column of the header is blank and there is a dislocation in the table.
Code
<table border="1">
<?php
$book_query = mysql_query("select * from book_master");
$i = 0;
while($row = mysql_fetch_assoc($book_query))
{
$columns = array_keys($row);
?>
<th>
<?php
foreach($columns as $column)
{
?>
<td><?php echo $column; ?> </td>
</th>
<?php
}
?>
<tr>
<?php
foreach($row as $key=>$value)
{
?>
<td><?php echo $value; ?></td>
<?php
}
?>
</tr>
<?php
$i++;
}
?>
</table>
EDIT:
Here is my print_r($columns) value:
Array ( [0] => Author Name [1] => Book Name [2] => Rating [3] => Location )
I know the problem is with the loop. Could someone help me out?

Answer 1

You can try to change
<th>
<?php
foreach($columns as $column)
{ ?>
<td><?php echo $column; ?> </td>
<?php
}
?>
</th>
to
<tr>
<?php
foreach($columns as $column)
{ ?>
<th><?php echo $column; ?> </th>
<?php
}
?>
</tr>

Just remove TH tag because its create one extra cell, so your layout messed up
<table border="1">
<?php
$book_query = mysql_query("select * from book_master");
$i = 0;
while($row = mysql_fetch_assoc($book_query))
{
if($i == 0){
$columns = array_keys($row);
?>
<?php
foreach($columns as $column){ ?>
<td><?php echo $column; ?> </td>
<?php } ?>
<?php } ?>
<tr>
<?php
foreach($row as $key=>$value){ ?>
<td><?php echo $value; ?></td>
<?php } ?>
</tr>
<?php
$i++;
}
?>
</table>

Hope this will help someone.
Just I have replaced the TH tag with TR and the output is perfect.
<table border="1">
<?php
$book_query = mysql_query("select * from book_master");
while($row = mysql_fetch_assoc($book_query))
{
$columns = array_keys($row);
?>
<tr>
<?php
foreach($columns as $column){ ?>
<td><?php echo $column; ?> </td>
<?php } ?>
</tr>
<tr>
<?php
foreach($row as $key=>$value){ ?>
<td><?php echo $value; ?></td>
<?php } ?>
</tr>
</table>
