How to Extract Values from php array

Question

I'm trying to return the LARGEST numerical value associated with the 'reduced' array below. Easy enough if there is one value but many have two- as below. I'm using

$reduced_array = $data['rates'][1]['rates'][0];

but this only works in returning the first value. I need to return just the highest value however- so below it would be 8. would something like

 if(count($data['rates'][1]['rates']) > 2) {
        ***return largest value here***

work? I'm just not sure how to perform the asterisked task- maybe a for loop? here is the array.

Array
(
[rates] => Array
    (
        [0] => Array
            (
                [name] => Super Reduced
                [rates] => Array
                    (
                    )

            )

        [1] => Array
            (
                [name] => Reduced
                [rates] => Array
                    (
                        [0] => 5
                        [1] => 8
                    )

            )

        [2] => Array
            (
                [name] => Standard
                [rates] => Array
                    (
                        [0] => 23
                    )

            )

        [3] => Array
            (
                [name] => Increased
                [rates] => Array
                    (
                    )

            )

        [4] => Array
            (
                [name] => Parking
                [rates] => Array
                    (
                    )

            )

    )

[disclaimer] => Rates data is based on information published by the European Commission, updated 1st January 2017.

Thanks for any help

Just grab the rates array, sort it in descending order, then grab the first value. — domsson

You can use max() for that.

$array = array(
    "rates" => array(
        array(
            "name" => "Super Reduced",
            "rates" => array()
        ),
        array(
            "name" => "Reduced",
            "rates" => array(
                5,
                8
            )
        )
    )
);

echo max($array["rates"][1]["rates"]); // 8

Easiest solution will be using of max on inner array example:

if(!empty($data['rates'][1]['rates'])) {
    $maxvalue = max($data['rates'][1]['rates']);
}
