Solutions to BIG5-HKSCS

It is very hard to find that PHP has always supported the problem of HKSCS which has been difficult for a long time. But not the HK-SCS, The BIG5-HKSCS.
The following is a solution to solve the HK increment character set:
The HTML faces are set as UTF-8,
Before importing data to analyticdb, iconv ('big5-HKSCS ', 'utf8', $ string)
Use the following function if Unicode is required
Function string2unicode ($ data, $ LANGUAGE)
{
$ DATA = nl2br (TRIM ($ data ));
$ DATA = str_replace ('<br/>', CHR (13), $ data );
$ STR = '';
Preg_match_all ("/[\ X80-\ xFF]?. /", $ Data, $ AR );
Debug ($ AR );
Foreach ($ ar [0] as $ V)
{
If ($ V! = ''& $ V! = CHR (13 ))
{
$ Str. = "". utf82unicode (iconv ($ language, "UTF-8", $ V )).";";
} Else {
$ Str. = $ V;
}
}
Return $ STR;
}
Function utf82unicode ($ c ){
Switch (strlen ($ C )){
Case 1:
Return ord ($ C );
Case 2:
$ N = (ord ($ C [0]) & 0x3f) <6;
$ N + = ord ($ C [1]) & 0x3f;
Return $ N;
Case 3:
$ N = (ord ($ C [0]) & 0x1f) <12;
$ N + = (ord ($ C [1]) & 0x3f) <6;
$ N + = ord ($ C [2]) & 0x3f;
Return $ N;
Case 4:
$ N = (ord ($ C [0]) & 0x0f) <18;
$ N + = (ord ($ C [1]) & 0x3f) <12;
$ N + = (ord ($ C [2]) & 0x3f) <6;
$ N + = ord ($ C [3]) & 0x3f;
Return $ N;
}
