How to read from multi-dimensional arrays in PHP?-ThrowExceptions

I’m trying to do something I’ve never tried before: reading from APIs, and using the returned values in my website. To do this I need to read from multi-dimensional arrays in PHP.

See below the result I am getting from the API callback, when I run the following lines of code:

$tempContents = json_decode($data, true);
echo '<pre'; print_r($tempContents); echo '</pre';

Results:

Array (
    [data] = Array
    (
        [boards] = Array
        (
            [0] = Array
            (
                [columns] = Array
                (
                    [0] = Array
                    (
                        [title] = Name
                    )
                    [1] = Array
                    (
                        [title] = note
                    )
                    [2] = Array
                    (
                        [title] = notes2
                    )
                    [3] = Array
                    (
                        [title] = Status
                    )
                )
            )
        )
    )
    [account_id] = xxxxxxx 
)

So that’s great, I can see the information there; however, I’m not sure about how to construct a foreach function to retrieve individual values. For example; the name of the second title value.

foreach($tempContents['data']['boards'][0]['columns'] as $title){
    echo $title['title'].PHP_EOL;
}

$finalArray = array_column($tempContents['data']['boards'][0]['columns'],'title');

foreach($finalArray as $title){
    echo $title.PHP_EOL;
}
