SOCKET_SEND(3) 1 SOCKET_SEND(3)socket_send - Sends data to a connected socketSYNOPSIS
int socket_send (resource $socket, string $buf, int $len, int $flags)
DESCRIPTION
The function socket_send(3) sends $len bytes to the socket $socket from $buf.
PARAMETERS
o $socket
- A valid socket resource created with socket_create(3) or socket_accept(3).
o $buf
- A buffer containing the data that will be sent to the remote host.
o $len
- The number of bytes that will be sent to the remote host from $buf.
o $flags
- The value of $flags can be any combination of the following flags, joined with the binary OR ( |) operator.
Possible values for $flags

| | |
| MSG_OOB | |
| | |
| | Send OOB (out-of-band) data. |
| | |
| | |
| MSG_EOR | |
| | |
| | Indicate a record mark. The sent data completes |
| | the record. |
| | |
| | |
| MSG_EOF | |
| | |
| | Close the sender side of the socket and include |
| | an appropriate notification of this at the end of |
| | the sent data. The sent data completes the trans- |
| | action. |
| | |
| | |
|MSG_DONTROUTE | |
| | |

SOCKET_READ(3) 1 SOCKET_READ(3)socket_read - Reads a maximum of length bytes from a socketSYNOPSIS
string socket_read (resource $socket, int $length, [int $type = PHP_BINARY_READ])
DESCRIPTION
The function socket_read(3) reads from the socket resource $socket created by the socket_create(3) or socket_accept(3) functions.
PARAMETERS
o $socket
- A valid socket resource created with socket_create(3) or socket_accept(3).
o $length
- The maximum number of bytes read is specified by the $length parameter. Otherwise you can use
,
, or to end reading
(depending on the $type parameter, see below).
o $type
- Optional $type parameter is a named constant:
o PHP_BINARY_READ (Default) - use the system recv() function. Safe for reading binary data.
o PHP_NORMAL_READ - reading stops at
or
.
RETURN VALUES socket_read(3) returns the data as a string on success, or FALSE on error (including if the remote host has closed the connection). The
error code can be retrieved with socket_last_error(3). This code may be passed to socket_strerror(3) to get a textual representation of the
error.
Note
socket_read(3) returns a zero length string ("") when there is no more data to read.

Hello,
I'm doing a very simple program which reads a file and sends whatever is in the file through a socket. Like the program "file2cable".
Let's say i have a file containing the following, which is a hex dump of an ARP request frame:

Can anyone tell what happens if each end writes at the same time on the same socket ?
- if one of them issues a read() after write() has completed, will it record into the buffer what the other sent ?
ex.
e1 writes to e2 - - - while - - - e2 writes to e1 (at the same time)
e1 read () - what... (1 Reply)
