<?php 
// Load metaverse client 
require_once 'mmetaverse/src/mjs/mmetaverse/client/MMetaverseClient.class.php';

// Try to open client connection 
try {
    // Grid User Info
    $firstname = 'Juan';
    $lastname = 'Perez';
    $password = '1234';
    $server = '192.168.1.2';
    $port = 9000;

    // Create a client a do login
    $client = new MMetaverseClient($server,$port);
    $client->login($firstname, $lastname, $password);

    // Sleep while the opensim opens the udp server and
    // Register the client 
    sleep(20);

    // Try to upload image using capabilities
    try {
        // Image Information
        $name = 'texture02';
        $description = 'Texture upload by MMetaverse';
        $content = file_get_contents('image01.jp2');

        // Get inventory and upload image 
        $inventory = $client->getInventory();
        $response = $inventory->uploadTexture($name, $description, $content);

        // Print the new texture uuid
        echo 'New Asset :' . $response->getHyphenated();
    } catch (Exception $e) {
        // Show the error information
        echo 'Error : ' . $e->getMessage();
    }

    // Close the connection with the simulator 
    $client->logout();
} catch (Exception $e) {
    // Show the error information
    echo 'Error : ' . $e->getMessage();
}
