Split query results in 2 div's - php

Question

i have this php mysql query
<?php
$product = mysql_query('SELECT * FROM products LIMIT 6 ');
$pro = mysql_fetch_assoc($product);
?>
Now that query will return 6 products from database and what i want to do is echo 3 products inside a <div> and the other 3 products inside another <div> like this
<div class="first-3>
///Here i want to echo 3 products from the query from 1-3
<?php echo $pro['title']; ?>
</div>
<div class="second-3>
///Here i want to echo the rest 3 products of the query from 4-6
<?php echo $pro['title']; ?>
</div>

Answer 1

<?php
$num = 6;
$product = mysql_query('SELECT * FROM products LIMIT $num');
$firstDiv = "";
$secondDiv = "";
$i = 0;
while ($pro = mysql_fetch_assoc($product)) {
if ($i < ($num /2)) {
$firstDiv .= $pro['title'];
}
else {
$secondDiv .= $pro['title'];
}
$i++;
}
?>
And:
<div class="first-3>
<?php $firstDiv ?>
</div>
<div class="second-3>
<?php $secondDiv ?>
</div>

Answer 2

Iterate and output the values.
<?php
$product = mysql_query('SELECT * FROM products LIMIT 6 ');
$i = 1;
echo '<div class="first-3">';
while ( $pro = mysql_fetch_assoc($product) ) {
if ($i === 3) {
echo '</div><div class="second-3">';
}
echo $pro['title'];
$i++;
}
echo '</div>';
?>
Note that it's not safe to use mysql_query, you should be using mysqli or preferrably PDO.

Answer 3

mysql_fetch_assoc is used to retrieve a row in the resultset.
Doc: http://php.net/manual/es/function.mysql-fetch-assoc.php
A loop is required to iterate on each row.
A very simple example:
// Get a collection of 6 results
$products = mysql_query('SELECT * FROM products LIMIT 6 ');
// iterate over the 6 results
$i=0;
echo '<div class="first-3>';
while ($pro = mysql_fetch_assoc($products)) {
$i++;
// Print an item
echo $pro["title"];
// If 3 items are printed end first div and start second div
if($i==3){
echo '</div><div class="second-3">';
}
}
echo '</div>';
// Free the collection resources
mysql_free_result($products);

Answer 4

Just set up a counter to divide in groups of 3:
$count = 0;
while (...)
{
// your code
$count++;
if ( ($count % 3) === 0 )
{
echo '</div><div class="...">';
}
}
Please note that the mysql_* functions are deprecated and you should switch to PDO or mysqli.

Answer 5

$product = mysqli_query($conn, 'SELECT * FROM products LIMIT 6 ');
$results = array();
while($pro = mysqli_fetch_assoc($product)) {
$results[] = $pro;
}
echo '<div class="first-3">';
for($i = 0; $i < 3; $i++) {
echo $results[$i]['title'];
}
echo '</div><div class="second-3">';
for($i = 3; $i < 6; $i++) {
echo $results[$i]['title'];
}
echo '</div>';

Everytime you get the multiple of 3, ($k % 3 == 0) you will increment the flag variable, you can do then some conditions with the variable flag, i used here iterators because the hasNext() beauty.
Example
$pro = array(1, 2, 3, 4, 5, 6);
$flag = 0;
$pro = new CachingIterator(new ArrayIterator($pro));
foreach ($pro as $k => $v) {
// if multiples 3
if ($k % 3 == 0) {
$flag++;
if ($flag == 1) {
echo '<div class="first-3" style="border:1px solid black;margin-bottom:10px;">';
} else if ($flag == 2) {
echo '</div>'; // Closes the first div
echo '<div class="second-3" style="border:1px solid red">';
}else{ // if you have more than 6
echo '</div>';
}
}
// insert Data
echo $v . '<br/>';
if (!$pro->hasNext())
echo '</div>'; // if there is no more closes the div
}
