How would you print with PHP the value of [product_price]?

Answer 1

To print only the field product_price who is in a array of objects make a foreach, example:

$items = array(); // esse array é do pergunta

foreach($items as $item)
{
    echo $item->product_price;
}

Answer 2

How the data is inside a array, you will need to use a loop as for, foreach or while, see below an example with foreach:

$dados = [];
foreach($dados as $item) {
    echo $item->product_price;
}

Answer 3

Assuming that this vector is in the variable $vector.

Code for printing the price of a specific item, for example of the first (heading 0):

echo $vetor[0]->product_price;

Code to print the price of all vector items:

foreach ($vetor as $produto){
    echo "Valor: ". $produto->product_price."<br/>";
}
