I have some PHP at coinbus.com that displays live and weighted prices. It was derived, if not flat out plagiarized from some other code here on the forums. You're welcome to it.
<?php
//first fetch the current rate from https://mtgox.com/api/0/data/ticker.php
$ch = curl_init('https://mtgox.com/api/0/data/ticker.php');
curl_setopt($ch, CURLOPT_REFERER, 'Mozilla/5.0 (compatible; MtGox PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
curl_setopt($ch, CURLOPT_USERAGENT, "CakeScript/0.1");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$mtgoxjson = curl_exec($ch);
curl_close($ch);
//decode from an object to array
$output_mtgox = json_decode($mtgoxjson);
$output_mtgox_1 = get_object_vars($output_mtgox);
$mtgox_array = get_object_vars($output_mtgox_1['ticker']);
//first fetch the current rate from http://bitcoincharts.com/t/weighted_prices.json
$ch = curl_init('http://bitcoincharts.com/t/weighted_prices.json');
curl_setopt($ch, CURLOPT_REFERER, 'Mozilla/5.0 (compatible; BitcoinCharts PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
curl_setopt($ch, CURLOPT_USERAGENT, "CoinBus.com/0.1");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$bitcoinchartjson = curl_exec($ch);
curl_close($ch);
//decode from an object to array
$output_bitcoincharts = json_decode($bitcoinchartjson);
$output_bitcoincharts_1 = get_object_vars($output_bitcoincharts);
$bitcoincharts_array = get_object_vars($output_bitcoincharts_1['USD']);
