Ahoy Sailors!
So I've begone a Parent/Child based application, I've currently got both the scripts to connect to each other & send & receive text, However there are two bugs.
First when the Child connects too the Parent for the first time, It works! But if you exit & start the Child script again without closing the Parent, You get an "socket_recv(): unable to read from socket [11]: Resource temporarily unavailable" error.
Child.php
<?php
$addr="127.0.0.1";
$port=220;
$timeout=0;
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
///////////////////
$dz = socket_connect($sock,$addr, $port);
$buf = "text";
$rec = socket_recv($sock, $buf, 2048,MSG_DONTWAIT);
while (1>0){
$buf = explode(":", $buf); //Function deciding
if ($buf[0]=='0'){
$fdb = "function not done yet";
}
if ($buf[0]=='1'){
echo $buf[1] . "\n";
}
sleep('5');
}
?>__________________
The second is only minor, The parent script, Even though in a loop, Only sends the specified text once per connection? If you where to restart the Child script, Then it would send it once more.
Parent.php
<?php
$host = "127.0.0.1";
$port = 220;
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
$result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
// Networking area, Creating, Binding & finally listing
while (1>0){
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
$out = "1:Ahoy!";
socket_write($spawn, $out, strlen ($out)) or die("Could not write output\n");
echo "Sent!";
sleep(6);
}
?>
