Мне нужно проанализировать данные и извлечь идентификатор, имя пользователя, телефон из файла JSON, который может быть недействительным JSON

Пример данных

Пример кода 

parseData($input) {

    // Some code to extract specific data from invalid JSON

    return $data;
}

$string = file_get_contents("test.json");

$arr = parseData(json_decode(utf8_encode($string), true));

$s=0;

foreach($arr as $item=> $value){
    $s=count($value); // WIN
}

echo $s;

Если вы протестируете json в каком-либо инструменте из ворса, таком как https://jsonlint.com/, вы увидите ошибку, и первая ошибка - двойная кавычка "" для определения параметров.

После удаления двойных кавычек возникает ошибка разделения объектов {}. Для каждого объекта вам нужно запятую, например {},{},{}

И последняя ошибка - у вас много объектов, и для правильной работы вам необходимо поместить объекты в массив, например [{},{},{}]

Я сделал пример возможного решения для ваших образцов данных
