求一正则

$str = "图片1:，图片2：";

回复讨论(解决方案)

$str = "图片1:，图片2：";preg_match_all('/src=([\'"])(.+)\1/isU', $str, $m);print_r($m);

Array(    [0] => Array        (            [0] => src='https://www.gxlcms.com/1.jpg'            [1] => src="https://img.gxlcms.com/2.jpg"        )    [1] => Array        (            [0] => '            [1] => "        )    [2] => Array        (            [0] => https://www.gxlcms.com/1.jpg            [1] => https://img.gxlcms.com/2.jpg        ))

一定要把单引号、双引号也匹配出来吗？

那就不明白你在想什么了

好吧，多谢老徐回答。
