Php Socket Server - Server Stops Responding

[ev5unleash1]

Hi all,

 

I'm currently trying to run a PHP Socket Server though I'm having trouble with responding after so many reconnects. It would seem after 3-5 reconnects that it will just stop taking connections altogether. Any ideas? Basically I want the script to do as it does right now, but be able to accept a new connection at any time. Though it only has to be one connection, so kicking the previous connection off doesn't matter to me.

 

Thanks,

 

<?php


echo "Web Socket Script  = Coded in PHP" . PHP_EOL;
echo $custom;
error_reporting(0);



function action_put($probe) {

$memcache = new Memcache;
$memcache->connect('localhost', 11211) or $error = "Memcache: Could not connect to Cache server";

$memcache->set('key', $probe, false) or $error = $error . ". Failed to save data at the server.";

if(isset($error)) { echo "Data not stored: " . $error; }
else { }

$respond = $memcache->get('key');

}


function action_get() {
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Memcache: Could not connect to Cache server");
$respond = $memcache->get('key');
return $respond;
}


function cachetodisk() {
$cache = action_get();
file_put_contents('probe.txt', $cache);
}


function disktocache() {
$disk = file_get_contents('probe.txt', 'r');
action_put($disk);

@requinix That's my old script regarding a socket server. This is a completely different where here I'm accepting socket connections as opposed to connecting to one.
