Descrierea

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

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

Când este stabilit în TRUE, fișierul este căutat și în căile specificate în include_path

context

Valorile întoarse

Erori/Excepții

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