复制代码 代码如下:
<?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
)
)
