Описание

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.

use_include_path

Когато е установен в TRUE, името на файла се търси също и в include_path

Връщани стойности
