匹配出$str内src里面的内容的正则应该怎么写?


回复讨论(解决方案)

$str = "图片1:<img  src='1.jpg' alt="求一正则" >,图片2:<img  src=\"2.jpg\" alt="求一正则" >";preg_match_all('/src=([\'"])(.+)\1/isU', $str, $m);print_r($m);

Array(    [0] => Array        (            [0] => src='1.jpg'            [1] => src="2.jpg"        )    [1] => Array        (            [0] => '            [1] => "        )    [2] => Array        (            [0] => 1.jpg            [1] => 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。
