PHP reads files and solves Chinese garbled UTF- 8

$opts = array(  
&#39;file&#39; => array(  
        &#39;encoding&#39; => "utf-8"  
  )  
);  
$opts = array(&#39;http&#39; => array(&#39;encoding&#39; => &#39;utf-8&#39;));  
$ctxt = stream_context_create($opts);  
$content = file_get_contents($filePath, FILE_TEXT, $ctxt);

The simplest is to change GF2312→UTF-8

$str=iconv("gb2312", "utf-8", $str);

It doesn’t work

$content
 = mb_convert_encoding(
$content
, 
"UTF-8"
, 
"auto"
);
