Cuando desarrollamos un site con soporte on-line vía Skype, puede ser interesante incluir en la propia página web el estado de nuestro usuario en Skype, para ver si estamos Online o no.

Hacer esto en PHP, realmente es bastante simple, y solo necesitamos crear un archivo class al que llamar desde donde nos interese.

Creamos un archivo class llamado "class.phpSkypeStatus.php" con este contenido:

<?php
/**
 * The class class.phpSkypeStatus.php
 * 
 * The class.phpSkypeStatus.php class is for viewing the online status of a skype user
 * please read: http://skype.com/share/buttons/status.html
 * 
 * @package phpSkypeStatus
 * @author Bastian Gorke <b.gorke@ipunkt.biz>
 * @version 2006-03-01
 * 
 * History:
 *     2006-03-01: bug fix
 *                 x error with getting xml/image is not longer shown
 *     2006-02-13: initial version

Y el ejemplo de su funcionamiento (llamada desde otro archivo):

<?php
require_once("class.phpSkypeStatus.php");

$skypeid="bastian.gorke";

// new status
$status = new phpSkypeStatus($skypeid);

// if param image = 1 return just the image
if ($_GET['image'] == "1"){
    $status->getImagePNG("smallclassic");
}
echo "<html><head><title>".$skypeid." status is ".$status->getText()."</title></head><body>";
echo "<h1>".$skypeid." status is ".$status->getText()."</h1>";
echo "<p>This is a simple example for the phpSkypeStatus class. As you can see my status is: <img src="".$PHPSELF."?image=1" /></p>";
echo "<p>In my language german this status is named ".$status->getText("de")."</p>";
echo "</body></html>";
?>

Esto es todo.
