The function
socket_write()
writes to the socket
socket
from
buffer
.
The optional parameter
length
can specify an
alternate length of bytes written to the socket. If this length is
greater then the buffer length, it is silently truncated to the length of
the buffer.
Returns the number of bytes successfully written to the socket or
FALSE
one error. The error code can be retrieved with
socket_last_error()
. This code may be passed to
socket_strerror()
to get a textual explanation of the
error.
Note:
socket_write()
does not necessarily write all bytes
from the given buffer. It's valid that, depending on the network
buffers etc., only a certain amount of data, even one byte, is written
though your buffer is greater. You have to watch out so you don't
unintentionally forget to transmit the rest of your data.
