PHP提取字符串中的图片地址[正则表达式]

复制代码 代码如下:
<?php
$str='<p><img border="0" src="/UploadFiles/2021-04-02/1246430143_1.jpg">$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="/UploadFiles/2021-04-02/1246430143_1.jpg">)

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