Read the first max_bytes from the buffer and drain the bytes read. If more max_bytes are requested than are available in the buffer, it only extracts as many bytes as available.

版本	说明
PECL event 1.6.0	Renamed EventBuffer::read()(the old method name) to EventBuffer::read(). EventBuffer::read() now takes only `max_bytes` argument; returns string instead of integer.
