Usage example
$words ="Chinese Abc";
function ex($str){return "[".$str."]";}
$qswh=new qswhGBK("qswhGBK.php");//If the file name It is qswhGBK.php, you can omit the parameter echo("Without parameters:".$qswh->gb2u($words));echo(" Call the built-in function htmlHex: ".$qswh->gb2u($words,1));echo(" Call the built-in function htmlDec:".$qswh->gb2u($words,2));echo(" Call the built-in function escape:".$qswh->gb2u($words,3));echo(" Call the built-in function u2utf8:".$qswh->gb2u($words,4));echo(" Call the custom function: ".$qswh->gb2u($words,ex)); The effect is as follows: without parameters: 4E2D6587416263 Call the built-in function htmlHex: Chinese Abc calls the built-in function htmlDec: Chinese Abc calls the built-in function escape:%u4E2D% u6587Abc calls the built-in function u2utf8:%e4%b8%ad%e6%96%87Abc calls the custom function: [4E2D][6587][41][62][63]ps.
