SplFileInfo::openFile — Gets an SplFileObject object for the file

설명

public SplFileObject SplFileInfo::openFile ([ string $open_mode = "r" [, bool $use_include_path = false [, resource $context = NULL ]]] )

Creates an SplFileObject object of the file. This is useful because SplFileObject contains additional methods for manipulating the file whereas SplFileInfo is only useful for gaining information, like whether the file is writable.

인수

open_mode

use_include_path

TRUE로 설정하면, include_path에서도 파일명을 찾습니다.

context

contexts에 대한 설명은 매뉴얼 context 섹션을 참고하십시오.

반환값

The opened file as an SplFileObject object.

오류/예외

A RuntimeException if the file cannot be opened (e.g. insufficient access rights).
