PHP explode function from checkboxes - php

Question

I have a form where I'm submitting some values (from checkboxes) to another page and on that page I'm using an explode function to break the string inside the array. But I'm getting an additional (+1) value when I put the count() function on the explode.
HTML
<form name = "view" method = "POST" action ="cart.php">
<table align = 'center' width = '100%' border = '4'>
<tr>
<td colspan = '20' align = 'center'><h2> Viewing all the Products </h2></td>
</tr>
<tr align = 'center'>
<th>Item ID</th>
<th>Name</th>
<th>Price</th>
<th>Select</th>
</tr>
<tr align = 'center' class = "odd">
<?php
while($row = mysql_fetch_array($run))
{
$i_id = $row['item_id'];
$i_name = $row['item_name'];
$i_price = $row['item_price'];
?>
<td><?php echo $i_id; ?></td>
<td><?php echo $i_name; ?></td>
<td><?php echo $i_price; ?></td>
<?php
$item = $i_name ." ". $i_price;
?>
<td><input type="checkbox" name="addcart[]" value="<?php echo $item; ?>" onClick="return KeepCount()" />Tick</td>
</tr>
<?php }?><input type = "hidden" name = "check">
<button type= "submit" onclick = "location.href = 'cart.php';" id = "cart">Add to Cart</button> <?php } ?>
</table>
</form>
PHP (on page 2)
$prd = implode(",",$_POST['addcart']);
$final = explode(",", $prd);
for($i=0; $i<=count($final); $i++)
{
echo count($final); //this is where I'm getting the +1 to original count and hence everything falls apart.
echo $final[$i];
}
Note: I have include all the essential files like config.php and everything in the PHP file already.

Answer 1

Why that much extra code, directly do like below:-
foreach($_POST['addcart'] as $val){
echo $val;
}

Answer 2

Since count() starts counting from 1 and for loop starting from 0.
Replace this line:
for($i=0; $i<=count($final); $i++)
with
for($i=0; $i<=count($final)-1; $i++)
