PHP提取字符串中的图片地址

<?php
$str='<p><img border="0" src="upfiles/2009/07/1246430143_1.jpg" alt=""/></p>';
$pattern="/<[img|IMG].*?src=[\'|\"](.*?(?:[\.gif|\.jpg]))[\'|\"].*?[\/]?>/";
preg_match_all($pattern,$str,$match);
print_r($match);
?>

结果显示：

Array
(
    [0] => Array
        (
            [0] => <img border="0" src="upfiles/2009/07/1246430143_1.jpg" alt=""/>
        )

    [1] => Array
        (
            [0] => upfiles/2009/07/1246430143_1.jpg
        )

)
