    Php socket server

    Hi, I am trying to use this code here.

    PHP Code:
    #!/usr/local/bin/php -q
    <?php
    //setting this to 0 lets scriphang around for ever
    set_time_limit(0);



    // defaults...

    define('MAXLINE'1024); // how much to read from a socket at a time
    define('LISTENQ'10); // listening queue
    define('PORT'10000); // the default port to run on
    define('FD_SETSIZE'5); // file descriptor set size (max number of concurrent clients)...


    // for kill the server

    function killDaemon()
    {

    I loaded the .php onto my webserver (that is a newly set up one, only an index.php file). and when I load it it's a blank page, so I think it's working. I then copy the fla file from the post #37 here http://board.flashkit.com/board/show...=391320&page=2

    but it doesnt seem to connect? Why might that be...

    I am trying port 1000, and in the php file I put the ip adress of the website that i got using http://www.selfseo.com/find_ip_address_of_a_website.php.

    and the flash file is loaded into the same directory on the server aswell as the html that displays the swf. and I also put the same ip adress into the flash file. but no connection. Any ideas?

    hmm

    well now i tried to leave the ip blank in flash, and i tried using #!/usr/local/bin/php -q as well, but it doesn't work. I tried to ping the site and use that ip.

    Safe mode is off, and I have all the socket functions available.. I tried some code that said it would bypass the security settings. didn't work..

    I tried deleting the code and renaming between so it would restart.

    also it seems to show this,
    #!/usr/lib/php -q

    or

    #!/usr/local/bin/php -q

    I think I tried another one too, so i am wondering if the path to my php.exe is wrong? Also, I tried to run the same socketserver.php file in another browser at the same time, but nothing interesting happens. The socketserver.php is in my root directory along with the flash and html.. I feel like I have tried everything, yet everyone else says there's is working fine.. I don't get it.. also i am using php5.3

    any help would be greatly appreciated on this reoccurring topic...
    this thing is just driving me nuts :P


    Thanks,
    Brick

    Stupid question, but why PHP and not something like ElectroServer? It's far harder and less effective to use PHP to make a socket server when you could use a purpose-built server designed just to do this - one that comes with many of examples and tutorials on how to write games against it.

    never tried it, I only read it in one of the posts but didn't go there. Is it one of those servers I need to give credit to in my game though?

    And that is def not a stupid question, I'll look into that. But I am also so frustrated with why it wont work lol! Would love to at least connect!

    The rule of thumb is that a high-quality, popular, multi-player game has between a 10 to 1 to a 100 to 1 "monthly active user" (people who play at least once per month) to concurrent player ratio. That means you would have 250 to 2500 monthly active users before you reach your 25 concurrent user count. Finally, the monthly active user ratio is always much less than your total registered user count. So you might have 10,000 registered players before you even have to consider paying for anything.

    Additionally, the cost is quite inexpensive and you only pay the difference in licenses so you can start small and grow. This is particularly true considering the product has cost us many hundreds of thousands of dollars to develop over the last 7 years, the price is extremely reasonable

    With that said, we are looking to increase the free user count as soon as we get an update to our licensing application complete.

    Ultimately, I'd focus on making a great game before worrying about an inexpensive price tag that you only pay once you are already successful.

    Enough said :P, Plus id be in the starting stage anyways for a few months. Now you say "us" so I assume you are part of the dev group? Now can I use the app twice to make 2 server rooms that host 25 each, or is that a rule breaking thing. I also wasn't even gonna do the register thing, just a connect and play against the world

    Yes, I'm one of the owners of Electrotank - the company that makes ElectroServer. Yes, you can run multiple instances like that no problem.
