I modified my script to
<?php
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);
$server = stream_socket_server("tcp://127.0.0.1:8080");
for ($i = 1; $i <= 50; $i++) {
var_dump($i);
stream_socket_client("tcp://127.0.0.1:8080");
//stream_socket_accept($server);
}
but it doesn't show any error. Am I doing something wrong it turning on
error reporting?

A huge synthesis of the code could be:
|$server= stream_socket_server("tcp://127.0.0.1:8080");
for ($i= 1; $i<= 50; $i++) {
var_dump($i);
stream_socket_client("tcp://127.0.0.1:8080");
}|
everything is fine for the first 35 clients, then the connections start
to slow down and they happen almost one per second.
What is the reason for these delays? Is it a configuration setting?
Something due to my operative system?
I'm using PHP 5.6.4-4 on ubuntu 15.04
I suggest you turn on error_reporting(-1). Then you'll probably see
that the client can't connect, and hits a timeout. At least on my
German Windows box after 32 clients I get:
| Warning: stream_socket_client(): unable to connect to
| tcp://127.0.0.1:8080 (Es konnte keine Verbindung hergestellt werden, |
da der Zielcomputer die Verbindung verweigerte.)
[A connection couldn't be established, because the host refused the
connection.]
There seems to be a limit on allowed TCP connections; switching to UDP
works fine, though.
