预定义常量

SplFileObject::DROP_NEW_LINE

Drop newlines at the end of a line.

SplFileObject::READ_AHEAD

Read on rewind/next.

SplFileObject::SKIP_EMPTY

Skips empty lines in the file. This requires the READ_AHEAD flag be enabled, to work as expected.

SplFileObject::READ_CSV

Read lines as CSV rows.

更新日志

版本 说明
5.3.9 SplFileObject::SKIP_EMPTY value changed to 4. Previously, value was 6.
