PHP Insert an ad div after every 5 rows results - php

Question

How could I go about inserting a div after every fifth row on result page?
I have a script that displays 15 rows from a database in every pagination.
This my entire script
<?php
$sql = "SELECT COUNT(id) FROM table";
$query = mysqli_query($db_conx, $sql);
$row = mysqli_fetch_row($query);
// Here we have the total row count
$rows = $row[0];
$page_rows = 15;
$last = ceil($rows/$page_rows);
if($last < 1){
$last = 1;
}
$pagenum = 1;
if(isset($_GET['pn'])){
$pagenum = preg_replace('#[^0-9]#', '', $_GET['pn']);
}
if ($pagenum < 1) {
$pagenum = 1;
}
else if ($pagenum > $last) {
$pagenum = $last;
}
// This sets the range of rows to query for the chosen $pagenum
$limit = 'LIMIT ' .($pagenum - 1) * $page_rows .',' .$page_rows;
$sql = "SELECT id, fname, image_text, address, contact, price, image FROM table WHERE fname LIKE '%".$search."%' $limit";
$query = mysqli_query($db_conx, $sql);
$textline1 = "table (<b>$rows</b>)";
$textline2 = "Page <b>$pagenum</b> of <b>$last</b>";
// Establish the $paginationCtrls variable
$paginationCtrls = '';
// If there is more than 1 page worth of results
if($last != 1){
if ($pagenum > 1) {
$previous = $pagenum - 1;
$paginationCtrls .= '<td><a class="pagenumber" href="'.$_SERVER['PHP_SELF'].'?pn='.$previous.'">Previous</a> </td> ';
for($i = $pagenum-3; $i < $pagenum; $i++){
if($i > 0){
$paginationCtrls .= '<td><a class="pagenumber" href="'.$_SERVER['PHP_SELF'].'?pn='.$i.'">'.$i.'</a> </td> ';
}
}
}
$paginationCtrls .= ''.$pagenum.' ';
for($i = $pagenum+1; $i <= $last; $i++){
$paginationCtrls .= '<td><a class="pagenumber" href="'.$_SERVER['PHP_SELF'].'?pn='.$i.'">'.$i.'</a></td> ';
if($i >= $pagenum+3){
break;
}
}
if ($pagenum != $last) {
$next = $pagenum + 1;
$paginationCtrls .= ' <td> <a class="pagenumber" href="'.$_SERVER['PHP_SELF'].'?pn='.$next.'">Next</a></td> ';
}
}
$list = '';
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
?>
<div class="light-purple column">
<table style="height:100px; border-bottom:#F88 solid 2px;" width="100%" border="0">
<tr>
<td>
<img src="img/<?php echo $row['image']; ?>" alt="No Image">
</td>
<td width="70%">
<div class="detail_text" style="font-weight:bold;"><input type="hidden" value="<?php echo $row['id']; ?>"/>
<?php echo $row['fname']; ?>
</div>
<div class="detail_text " ><?php echo $row['image_text']; ?></div>
<div style="color: #999; font-weight: bold;"><?php echo $row['address']; ?></div>
<div class="detail_text" style="font-weight:bold; color: #606;">
<table width="95%" border="0">
<tr>
<td width="51%"><?php echo $row['contact']; ?></td>
<td width="49%"><?php echo $row['price']; ?></td>
</tr>
</table>
</div>
</td>
</tr>
</table>
</div>
<?php }
?>
I want to able to put an ad div in every 5 rows something like this "
<div class="ad"></div>
<row> content </row>
<row> content </row>
<row> content </row>
<row> content </row>
<row> content </row>
<div class="ad"></div>
<row> content </row>
<row> content </row>
<row> content </row>
<row> content </row>
<row> content </row>
<div class="ad"></div>
Can anyone assist me as to how could I set up the PHP script that will allow me to count the rows returned and after every certain number of rows , insert an ad script? Or is there a way to do this within rows itself?

Answer 1

You can use modulus operator,
$count = 1;
while{
if($count % 5 == 0)
echo '<div class="add"></div>';
$count++;
}

Answer 2

Just add a count variable to count till 5 and then reset to zero inside your loop.
$count=0;
while{
echo "<row> content </row>";
$count++;
if($count>=5)
{
echo "<div class="ad"></div>";
$count=0;
}
}
