php mysql_fetch_array every 25 items wrap a div - php

Question

I want to mysql_fetch_array 100 items from mysql database. then every 25 items wrap a div.
also, I make a total items result check.
My code as below, but it will add <div> to every item, no as my require. So how to make it easier? Thanks.
if (mysql_num_rows($result) != 0) {
$total = mysql_num_rows($result);
$num = 1;
while ($row = mysql_fetch_array($result)) {
if ($num === 1) {
echo '<div>';
}
echo $row['title'] . '<br />';
if ($total < 26) {
echo '</div>';
}
else {
if ($num === 26) {
echo '<div>';
}
if ($total < 51) {
echo '</div>';
}
else {
if ($num === 51) {
echo '<div>';
}
if ($total < 76) {
echo '</div>';
}
else {
if ($num === 75) {
echo '<div>';
}
if ($total < 101) {
echo '</div>';
}
}
}
}
$num++;
}
}

Answer 1

You can use the mod operator.
See: http://php.net/manual/en/internals2.opcodes.mod.php
echo '<div>';
while($row = mysql_fetch_array($result)){
....
if (($num % 25) === 1) { echo '</div><div>' }
$num++;
}
echo '</div>';

Answer 2

Try This...
if(mysql_num_rows($result)!=0){
$total = mysql_num_rows($result);
$num=1;
while($row = mysql_fetch_array($result)){
if($num===1)
echo '<div>';
echo $row['title'].'<br />';
if($num==25){
echo '</div>';
$num=1;
}
$num++;
}
}

Answer 3

use the mod operator.
$num =1;
while($row = mysql_fetch_array($result)){
if (($num % 25) === 1) { echo '<div>' }
-------here data ----
if (($num % 25) === 0) { echo '</div>' }
$num++;
}

My advice is to separate your concerns... Give it a shot more like this:
// first get all your data.
$results = array();
while($row = mysql_fetch_array($result)){
$results[] = $row;
}
// now you have an array of all of your records.
if (!empty($results)) {
// total count of the array up front.
$total = count($results);
$interval = 0;
// save the data in a buffer for echoing later.
$buffer = array('<div>');
foreach($results as $row) {
$buffer[] = $row['title'] . '<br />';
if (++$interval === 24) { // notice the prefix ++
$interval = 0;
// close and re-open divs
$buffer[] = '</div><div>';
}
}
// one final close tag
$buffer[] = '</div>';
// now we zip it up and echo the content.
echo implode('', $buffer);
}

Here is how I do it...
$count = 0;
while($row = mysql_fetch_array($result)){
if ($count%$25 == 0)
{
echo "<div>";
}
//whatever your data goes here
count++
if ($count%$25 == 0)
{
echo "</div>";
}
}
