У меня есть php-скрипт, который работает на регулярной основе, обрабатывает 100 лучших строк CSV-файла. Когда это будет сделано, я хочу, чтобы он удалял обработанные строки из файла CSV.Как удалить 100 строк из файла CSV с помощью PHP
Я пробовал приведенный ниже код, но он ничего не удаляет. Я не уверен, что лучший способ сформулировать условие в PHP и не уверен, что положить для $ id. Я устанавливал количество строк в 5 для целей тестирования. Вероятно, неправильный синтаксис неправильный.
Любые предложения? Советы?

}

fclose($file_handle);
