我要匹配一篇文章内容里面的所有图片，于是我写了下面这样一个正则。

$pattern = "/<img.*src=['\"](.*?)\/?>/i";
preg_match_all($pattern, $content, $match);
echo '<pre>',$content;print_r($match);exit;

打印结果如下：

Array
(
    [0] => Array
        (
            [0] => <img alt="在这里插入图片描述" src="/uploads/image/220915/65ff3683fe2c43c08b7afca44f172d59.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_Q1NETiBATWF0Y2hfaA==,size_21,color_FFFFFF,t_70,g_se,x_16" />
            [1] => <img alt="在这里插入图片描述" src="/uploads/image/220915/f525cd92182e4538ad89950db120a70b.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_Q1NETiBATWF0Y2hfaA==,size_20,color_FFFFFF,t_70,g_se,x_16" />
            [2] => <img alt="在这里插入图片描述" src="/uploads/image/220915/5791f45347e3487894bf31ebaffad50f.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_Q1NETiBATWF0Y2hfaA==,size_20,color_FFFFFF,t_70,g_se,x_16" />
            [3] => <img alt="在这里插入图片描述" src="/uploads/image/220915/81e8867c2adf4c6aaf66fbe6935d89a8.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_Q1NETiBATWF0Y2hfaA==,size_47,color_FFFFFF,t_70,g_se,x_16" />
        )

    [1] => Array
        (
            [0] => /uploads/image/220915/65ff3683fe2c43c08b7afca44f172d59.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_Q1NETiBATWF0Y2hfaA==,size_21,color_FFFFFF,t_70,g_se,x_16"

        )

我现在不知道如何清掉 $match[1] 结果里面的最后的双引号，我的想法是把正则改成如下：

$pattern = "/<img.*src=['\"](.*['\"]$)?\"\/?>/i";

想法就是src里面的那些任意字符，也就是 .* 这个排除双引号这个字符，现在这个写法是啥都匹配不到了，哈哈哈，还请大神帮忙指点一二，谢谢。

直接这样就好了 <img.*?\ssrc="([^"]+)"

补充内容（部分语言里面，\1 可能要写作 \\1）

<img.*?\ssrc=(?:["']?)([^"'>]+)
