streamWrapper::stream_read — Read from stream

Описание

public string streamWrapper::stream_read ( int $count )

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

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

Параметри

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

Връщани стойности

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.

Грешки/Изключения

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

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

Бележки

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