Как повысить производительность этого кода в php?
или любой альтернативный метод, чтобы выяснить, комментарий, если строка начинается с @ затем вызвать at() или если строка начинается с "#" затем вызвать hash()

здесь образец комментарий "#hash @at ###@@tag";

Answer 2

• использование strpos или preg_match или strstr
• Пожалуйста, обратитесь к строковым функциям в php. Вы можете сделать это в строке или двух с встроенными функциями.
• Если это не соответствует правильному написанию регулярного выражения.
