# streamWrapper::stream_read

(PHP 4 >= 4.3.2, PHP 5)

streamWrapper::stream_read — Read from stream

### Beschreibung

public string streamWrapper::stream_read ( int `$count` )

This method is called in response to fread() and fgets().

> Hinweis: Remember to update the read/write position of the stream (by the number of bytes that were successfully read).

### Parameter-Liste

`count`

  How many bytes of data from the current position should be returned.

### Rückgabewerte

If there are less than `count` bytes available, return as many as are available. If no more data is available, return either `FALSE` or an empty string.

### Fehler/Exceptions

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

> Hinweis: If the return value is longer then `count` an `E_WARNING` error will be emitted, and excess data will be lost.

### Anmerkungen

> Hinweis: streamWrapper::stream_eof is called directly after calling streamWrapper::stream_read to check if EOF has been reached. If not implemented, EOF is assumed.
