streamWrapper::stream_read — Read from stream

### Descrierea

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

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

> Notă:

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

### Parametri

`count`

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

### Valorile întoarse

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.

### Erori/Excepții

Emite o eroare `E_WARNING` dacă apelul acestei metode eșuează (de ex. nu este implementată).

> Notă:

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

### Note

> Notă:

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

Avertizare

When reading the whole file (for example, with file_get_contents()), PHP will call streamWrapper::stream_read() followed by streamWrapper::stream_eof() in a loop but as long as streamWrapper::stream_read() returns a non-empty string, the return value of streamWrapper::stream_eof() is ignored.
