我使用目前正在开发项目 xampp 的 codeigniter 和 imap php。由于某种原因，他们嵌入的图像没有显示。
在我的 getBody() 函数中，我有这个回调
$body = preg_replace_callback(
'/src="cid:(.*)">/Uims',
function($m) use($email, $uid){
//split on @
$parts = explode('@', $m[1]);
//replace local path with absolute path
$img = str_replace($parts[0], '', $parts[0]);
return "src='$img'>";
},
$body);
我收到错误
问题：如何确保它为文本/html 正文等获取正确的图像。
