AWwww god....im so sorry !
Didint remove my own ip:port in the script :~(
Here it comes my "final" again for the public ( if it becomes puplic at php.net)
Content:
fsockopen()
stream_select() instead of socket_get_status()
detecting tiemout.
generell example of useing sockets fgets/fputs
<?
class sock {
var $fp;
function sock(){
//
}
function connect($host,$port,$timeout = 5){
$this->fp=@fsockopen($host, $port, $errno, $errstr, $timeout);
if (!$this->fp){
return false;
}
return true;
}
function is_Connected() {
//Returns 0=no longer active / 1 = active
return !feof($this->fp);
}
function can_read (){
$set = array($this->fp);
$ret = stream_select($set, $b = NULL, $c = NULL, 0,500);
if($ret === FALSE){
echo "Error: stream_select() failed \n";
return False;
}
if($ret > 0){
//Socket has something for us
return True;
}
//Socket available but has nothing to read
return NULL;
}
function write ($string) {
if (feof($this->fp)) {
//Cant write to server (ping out prolly)
return false;
}
if ($string && !fputs($this->fp, $string . "\n")) {
//Cant write to server
return false;
}
return true;
}
function read ($len = 4096) {
if(!$this->can_read()){
//Nothing to read from server
return false;
}
return fgets($this->fp,$len);
}
}
?>
<?
//Example
$sock = new sock();
if ($sock->connect("host","port")){
$data = "";
while(TRUE){
echo "Read<br>";
if(false === ($data = $sock->read()) ){
break;
}
echo "$data<br>";
}
if(!$sock->write("Hallo")){
echo "Error write";
exit;
}
if(!$sock->is_Connected()){
echo "Server is outpinged";
exit;
}
}else{
echo "Cant connect";
}
?>
