HTTP Socket

Deze socket vond ik op het internet, ik heb het ook al op een ander forum geplaatst maar ik dacht misschien kan hij hier ook 

ik gebruik deze socket voor de DirectAdmin API's maar hij kan eigenlijk als socket gebruikt worden voor vanalles. (als het te doen valt met een http-socket uiteraard ;))

Een voorbeeld van het gebruik is wel voor de api's van DA.

VOORBEELD:

php code - Bekijk de code zonder highlighting - Klap code in 
  1. <?php
  2. include("socket.class.php");
  3.  
  4. # gebruikersnaam voor DA
  5. $username = '';
  6.  
  7. # wachtwoord voor DA
  8. $pass = '';
  9.  
  10. # domein waar DA op draait.
  11. $domein = '';
  12.  
  13. //nou de socket is geinclude kunnen we hem starten
  14. $sock = new HTTPSocket;
  15.  
  16. //nu gaan we inloggen in Direct Admin (verander wel de gegevens)
  17. $sock->connect($domein, 2222);
  18. $sock->set_login($username, $pass);
  19.  
  20. $sock->set_method('POST');
  21.  
  22. $sock->query('/CMD_API_POP', array( 'action' => 'create', 'domain' => $domein, 'user' => 'apidemo', 'passwd' => 'test', 'quota' => 0), 1);
  23.  
  24. $result = $sock->fetch_body();
  25. echo $result;
  26.  
  27. ?>


de download komt binnenkort, ik ben bezig m'n open source library bij te werken.
