socket_write
SOCKET_WRITE(3) 1 SOCKET_WRITE(3)socket_write - Write to a socketSYNOPSIS
int socket_write (resource $socket, string $buffer, [int $length])
DESCRIPTION
The function socket_write(3) writes to the $socket from the given $buffer.
PARAMETERS
o $socket
-
o $buffer
- The buffer to be written.
o $length
- The optional parameter $length can specify an alternate length of bytes written to the socket. If this length is greater than
the buffer length, it is silently truncated to the length of the buffer.
RETURN VALUES
Returns the number of bytes successfully written to the socket or FALSE on failure. The error code can be retrieved with
socket_last_error(3). This code may be passed to socket_strerror(3) to get a textual explanation of the error.
Note
It is perfectly valid for socket_write(3) to return zero which means no bytes have been written. Be sure to use the === operator to
check for FALSE in case of an error.
NOTES
Note
socket_write(3) 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 uninten-
tionally forget to transmit the rest of your data.
