PHP simple method to determine text encoding_php skills

The example in this article describes how to simply determine the text encoding in PHP. Share it with everyone for your reference. The details are as follows:

Here, a loop encoding of the text is used to determine whether it belongs to this encoding.

public function chkCode($string) {
$code = array(
 'ASCII',
 'GBK',
 'UTF-8'
);
foreach ($code as $c) {
 if ($string === iconv('UTF-8', $c, iconv($c, 'UTF-8', $string))) {
  return $c;
 }
}
return null;
}

I hope this article will be helpful to everyone’s PHP programming design.
