PHP function to get the encoding format of a string

$encode = mb_detect_encoding($string, array("ASCII",'UTF-8′,"GB2312′,"GBK",'BIG5′));
echo $encode;

Now you know what encoding format it is.

In addition, if you want to transcode it, you can refer to the following code:

if ($encode == “UTF-8″){
$string = iconv("UTF-8″,"GBK",$string);
}
