I messed around with the stock quote retrieval class, and made the get() function in it to get multiple quotes rather than just a single one. Example here

<?php

                                // put this class in a file called quote.inc if you use the example below

                                class quote {

                                    function get($symbols){

                                        $url = sprintf('http://finance.yahoo.com/d/quotes.csv?s=%s&f=sl1d1t1c1ohgv', implode(',', $symbols));

                                        $fp = fopen($url, 'r');

                                        if(!$fp){

                                            $this->StockQuote[0]['ERROR'] = 1;

                                        } else {

                                            $x = 1;

                                            while($row = fgetcsv($fp, 1000, ',')){

                                                $this->StockQuote[$x]['symbol'] = trim(preg_replace('/"/', '', $row[0]));

                                                $this->StockQuote[$x]['last'] = trim($row[1]);

                                                $this->StockQuote[$x]['date'] = trim(preg_replace('/"/', '', $row[2]));

                                                $this->StockQuote[$x]['time'] = trim(preg_replace('/"/', '', $row[3]));

                                                $this->StockQuote[$x]['change'] = trim($row[4]);

                                                $this->StockQuote[$x]['open'] = trim($row[5]);

                                                $this->StockQuote[$x]['high'] = trim($row[6]);

                                                $this->StockQuote[$x]['low'] = trim($row[7]);

                                                $this->StockQuote[$x]['volume'] = trim($row[8]);

                                                $x++;

                                            }

                                            fclose($fp);

                                            $this->StockQuote[0]['CVS_URL'] = $url;

                                            $this->StockQuote[0]['SYMBOL_COUNT'] = ($x - 1);

                                        }

                                    }

                                }
?>

Usage Example

<?php
 require('quote.inc');
 $sqa = (isset($sqa)) ? explode(',', $sqa) : array('MSFT', 'YHOO', 'RHAT');
 $q = new quote;
 $q->get($sqa);
 ?>
 <font size="2" face="Arial, Helvetica">

                            <?php if($q->StockQuote[0]['ERROR'] != 1): ?>

                            <?php for($i=1;$i<=$q->StockQuote[0]['SYMBOL_COUNT'];$i++): ?>
 <b><?=$q->StockQuote[$i]['symbol']?></b>

                            <font size="1"><?=$q->StockQuote[$i]['last']?></font><br>

                            <?php endfor; ?>

                            <?php else: ?>

                            <b>Stock quote retrieval error.</b><br>

                            <?php endif; ?>
 </font>

                            <form action="<?=$PHP_SELF?>" method="GET">

                            <input type="text" name="sqa" value="<?=implode(',', $sqa)?>">

                            <input type="submit" value="Get Quotes">

                            </form>
