результаты анализа данных в неопределенном начале, stripos ничего не возвращает

Я пытаюсь проанализировать конфиденциальные данные различных форматов, чтобы проанализировать конфиденциальные данные рядом с конкретными тегами в данных, будь то «cvv», «номер карты» или что-то подобное, что у меня есть в моем массиве $ nonos и расширении $ parseNew. Когда я пытаюсь определить, совпадают ли один из тегов и один из моих «нет-нет», стрипы также, похоже, ничего не возвращают или без пробелов, и я получаю несколько ошибок:

$parseNew is an optional field to parse other sensitive information that matches the type of information entered into $parseNew, such as the transaction amount.
if the strings in $parseNew matches any field in the data given, then that data will be parsed as well assign each piece of given test data to a variable for each to be passed into helcimTest. Because of the variance of the data,
