Beschreibung

public SplFileInfo::openFile(string $mode = "r", bool $useIncludePath = 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.

mode

The mode for opening the file. See the fopen() documentation for descriptions of possible modes. The default is read only.

useIncludePath

Wenn dieser Parameter auf true gesetzt ist wird auch im include_path nach dem Dateinamen gesucht.

context

Eine Beschreibung von contexts finden Sie im Abschnitt Kontextoptionen und -parameter dieses Handbuchs.

R├╝ckgabewerte

The opened file as an SplFileObject object.

Fehler/Exceptions

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