separating and adding the array data - php

Question

I have an array like this, which has the product selected data.
$option_data[] = array(
'product_option_id' => $product_option_id,
'product_option_value_id' => $option_value,
'name1' => $option_value['name'],
'option_id' => $option_query->row['option_id'],
'option_value_id' => $option_value_query->row['option_value_id'],
'name' => $option_query->row['name'],
'option_value' => $option_value_query->row['name'],
'type' => $option_query->row['type'],
'quantity' => $option_value_query->row['quantity'],
'subtract' => $option_value_query->row['subtract'],
'price' => $option_value_query->row['price'],
'sdate' => $option_value_query->row['sdate'],
'edate' => $option_value_query->row['edate'],
'price_prefix' => $option_value_query->row['price_prefix'],
'points' => $option_value_query->row['points'],
'points_prefix' => $option_value_query->row['points_prefix'],
'weight' => $option_value_query->row['weight'],
'weight_prefix' => $option_value_query->row['weight_prefix']
);
And I need the values for price, So I have assigned price value like this
$pricelist = $option_value_query->row['price'];
Actually it has two values , now I want to add those two values. I am not getting how to separate it and add those values.
EDITED ****
My function is like this
public function getProducts12() {

$product_id = $product[0];
$stock = true;
//echo $product_id;
// Options

$options = unserialize(base64_decode($product[1]));
