socket_send — Sends data to a connected socket

Description

socket_send(
    Socket $socket,
    string $data,
    int $length,
    int $flags
): int|false

The function socket_send() sends length bytes to the socket socket from data.

Parameters

socket

A Socket instance created with socket_create() or socket_accept().

data

A buffer containing the data that will be sent to the remote host.

length

The number of bytes that will be sent to the remote host from data.

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 transaction.
`MSG_DONTROUTE`	Bypass routing, use direct interface.

Return Values

socket_send() returns the number of bytes sent, or false on error.

Changelog

Version	Description
8.0.0	`socket` is a Socket instance now; previously, it was a resource.

$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); //protocolo UDP
//$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); //protocolo TCP

//obtengo valor en bytes
$len = strlen($msg->toString(1));

//envio informacion a socket
$sendMsg = socket_send($sock, $msg->toString(1), $len, MSG_DONTROUTE);

//cierro conexion iniciada
socket_close($sock);
