 需要把上面这段html中的图片网址，上传到自己的服务器，并做好映射。

提取url：

preg_match_all('/<img[^>]*src\s?=\s?[\'|"](?!http:\/\/img.jinyuanbao|http:\/\/img.jybtest)([^\'|"]*)[\'|"]/is', $content, $picarr);

这段代码的意思是提取非img.jinyuanbao和img.jybtest开头的网址。提取完毕，等到数组$picarr;

我们把$picar[1]中的图片连接存在oss；

https://img.alicdn.com/imgextra/i1/1696415374/TB2BDgldpXXXXXSXXXXXXXXXXXX_!!1696415374.jpg
存储在OSS上
http://img.jybtest.com/425968826991101.jpg




得到一个映射的数组$pics:




$pics = array(
'https://img.alicdn.com/imgextra/i1/1696415374/TB2BDgldpXXXXXSXXXXXXXXXXXX_!!1696415374.jpg' => 'http://img.jybtest.com/425968826991101.jpg'


);

foreach ($pics as $k => $v) {


    $content = str_replace($k, $v, $content);
  }


//或者


$k = array_map(function($item) {return '/'.str_replace('/', '\/', $item).'/';}, array_keys($pics));


$v = array_values($pics);
$content = preg_replace($k, $v, $content);
print_r($content);






preg_replace看出这个很方便地！
