This is the code I used for decoding

function b() {
    $string = file_get_contents("/home/linux/Public/test/a.json");
    $json_a = json_decode($string, true);
    print_r($json_a);
        foreach ($json_a as $person_name) {
        print_r($person_name);
    }
}

It prints Invalid argument supplied for foreach() as error. I removed all response used only one response, then it works fine.

If you use newlines to separate each json, you could do

foreach (file($file_name) as $json_plain) { print_r(json_decode($json_plain, true)); }

file() could split file into an array of lines, so you can decode each line.
