# streamWrapper::stream_open

(PHP 4 >= 4.3.2, PHP 5)

streamWrapper::stream_open — Opens file or URL

### Descripción

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()).

### Lista de parámetros

`path`

  Specifies the URL that was passed to the original function.

  > Note: The URL can be broken apart with parse_url().

`mode`

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

  > Note: 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.

### Valores retornados

Devuelve `TRUE` si todo se llevó a cabo correctamente, `FALSE` en caso de fallo.

### Errors/Exceptions

Emits `E_WARNING` if call to this method fails (i.e. not implemented).

### Notes

> Note: The streamWrapper->context property is updated if a valid context is passed to the caller function.
