streamWrapper::stream_open

(PHP 4 >= 4.3.2, PHP 5)

streamWrapper::stream_open — Opens file or URL

Beschreibung

public bool streamWrapper::stream_open ( string $path , string $mode , int $options , string &$opened_path )

This method is called immediately after the wrapper is initialized (f.e. by fopen() and file_get_contents()).

Parameter-Liste

path

Specifies the URL that was passed to the original function.

Hinweis: The URL can be broken apart with parse_url(). Note that only URLs delimited by :// are supported. : and :/ while technically valid URLs, are not.

mode

The mode used to open the file, as detailed for fopen().

Hinweis: Remember to check if the mode is valid for the path requested.

options

Holds additional flags set by the streams API. It can hold one or more of the following values OR'd together.

Flag	Description
`STREAM_USE_PATH`	If `path` is relative, search for the resource using the include_path.
`STREAM_REPORT_ERRORS`	If this flag is set, you are responsible for raising errors using trigger_error() during opening of the stream. If this flag is not set, you should not raise any errors.

opened_path

If the path is opened successfully, and STREAM_USE_PATH is set in options , opened_path should be set to the full path of the file/resource that was actually opened.

Rückgabewerte

Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE.

Fehler/Exceptions

Wirft E_WARNING, wenn der Aufruf dieser Methode fehlschlug (z.B. weil sie nicht implementiert ist).

Anmerkungen

Hinweis: Die streamWrapper->Kontext-Eigenschaft wird, wenn verfügbar, aktualisiert, wenn der aufrufenden Funktion ein gültiger Kontext übergeben wurde.
