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_AHEADflag 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. |
