SplFileObject 類(lèi)

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

簡(jiǎn)介

SplFileObject 類(lèi)為文件提供了一個(gè)面向對象接口。

預定義常量

SplFileObject::DROP_NEW_LINE

刪除行尾的換行符。

SplFileObject::READ_AHEAD

使用 rewind 或 next 方法時(shí)，從文件中讀取一行數據。

SplFileObject::SKIP_EMPTY

跳過(guò)文件中的空白行。這需要啟用 READ_AHEAD 標志，以達到預期的效果。

SplFileObject::READ_CSV

以 CSV 行的形式讀取。
