Force table to display 5 rows with or without data - php

Question

I have to display a table of 5 rows fetching from MySQL database using PHP. From the code below, if I have 3 rows in database, it will display only 3 rows. But, I need to display 5 rows with 2 empty rows along with 3 fetched rows. If there are no records found in the database, I should display 5 empty rows. I need your help on that.
Note: I am generating a report using PHP and MySQL. From the above method, I can fix the table height and so report will generate without any overlaps.
CODE:
<?php
$select= "select * from table where id=1";
$select2= mysql_query($select);
$select3= mysql_num_rows($select2);
$row_count = 1;
while($row = mysql_fetch_assoc($select2)){
?>
<tr>
<td ><?php echo $row_count;?>.</td>
<td ><?php echo $rows['id']; ?></td>
<td ><?php echo $rows['name']; ?></td>
<td ><?php echo $rows['phone_number']; ?></td>
</tr>
<?php $row_count++;
}?>

Answer 1

As you are already counting the $row_count variable, you can add simple while loop, like this:
<?
while($row_count < 5){
?>
<tr>
<td > </td>
<td > </td>
<td > </td>
<td > </td>
</tr>
<?php $row_count++;
}?>
What is ? Is it needed?

Answer 2

This should do the trick.
<?php
$select= "select * from table where id=1";
$select2= mysql_query($select);
$select3= mysql_num_rows($select2);
$row_count = 1;
while($row = mysql_fetch_assoc($select2)){
?>
<tr>
<td ><?php echo $row_count;?>.</td>
<td ><?php echo $rows['id']; ?></td>
<td ><?php echo $rows['name']; ?></td>
<td ><?php echo $rows['phone_number']; ?></td>
</tr>
<?php $row_count++;
}
if ($row_count < 5){
for ($i=1; $i <= (5-$row_count); $i++){
?>
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
<?php
}
}
?>

Answer 3

You appear to have two distinct problems (albeit related).
If you only want five rows even if your query returns twenty, you can either use the control variable $row_count to only output rows for the first five, or (preferably) just add limit 5 on to your query to get five rows or less.
The second problem is what to do if it returns less than five rows. In that case, use the control variable to output blank rows, something like adding the following to the end:
<?php
while ($row_count < 5) {
?>
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</tr>
<?php
$row_count++;
}
?>

while($row = mysql_fetch_assoc($select2)){
?>
<tr>
<td ><?php echo $row_count;?>.</td>
<td ><?php echo $rows['id']; ?></td>
<td ><?php echo $rows['name']; ?></td>
<td ><?php echo $rows['phone_number']; ?></td>
</tr> <?php }
if($select3<5){
for($i=1;$i<5-$select3;$i++){?>
<tr>
<td ></td>
<td ></td>
<td ></td>
<td ></td>
</tr>
<?php }
}
