Getting array values into a string

I output a PHP object via a loop but withing this look I have a few nested arrays. 

[categories] => Array
(
    [0] => Array
    (
        [0] => Chinese
        [1] => chinese
    )

    [1] => Array
    (
        [0] => Vietnamese
        [1] => vietnamese
    )
)

[phone] => 5123355555

I can get the phone like this:

$response->businesses[$x]->phone

How do I get categories (first value) into a string like this:

Chinese, Vietnamese

You can achieve with array_column() :

$newArray = array_column($response->businesses[$x]->categories, 0);

It returns an array with the column 0. So the response will be:

print_r($newArray);
//Array ( [0] => Chinese [1] => Vietnamese )

Then you can join it safely:

$newString = implode(",", $newArray)
echo $newString; // "Chinese, Vietnamese"

implode(', ', array_map(function($item) {
       return $item[0];
}, $response->businesses[$x]->categories));
