Find the most affordable rate in the JSON data without knowledge of the parent label

I am seeking to extract the best deal from JSON data obtained through an API call and decoded using json_decode.

The structure is as follows: products productnumber -> price

$product_array['products'][..changingnumber..]['value']

Without knowing the product number (and not needing it), I aim to identify the lowest price among all combined product numbers.

$price = min($product_array['products'][..changingnumber..]['value']);

Is there a method to accomplish this task? Alternatively, are there any resources or documentation available to assist with this?

Answer №1

To start, map out the 'value'-s and convert them into a straightforward array that includes all the prices:

$all_prices = array_map(function($item) {
    return $item['value'];
}, $product_array['products'])

Next, simply select the minimum value:

$price = min($all_prices);

You can also combine these steps into one statement:

$price = min(array_map(function($item) {
    return $item['value'];
}, $product_array['products']));
