Hello all,
I have PHP ver4.0.6 and MapServer version 3.5. and the dbms is =
postgresql7.1.3.I want to show the big5 on my map.My db had already =
converted the unicode to the big5,but the map on web still show the =
unicode.So I want to use php/mapscript to convert the word.following is =
the program that download on web:
<?php
   Function U2Utf8($c){
      If($c < 0x80) {
         $str.=3D$c;
      }ElseIf($c < 0x800) {
         $str.=3D(0xC0 | $c>>6);
         $str.=3D(0x80 | $c & 0x3F);
      }ElseIf($c < 0x10000) {
         $str.=3D(0xE0 | $c>>12);
         $str.=3D(0x80 | $c>>6 & 0x3F);
         $str.=3D(0x80 | $c & 0x3F);
      }ElseIf($c < 0x200000) {
         $str.=3D(0xF0 | $c>>18);
         $str.=3D(0x80 | $c>>12 & 0x3F);
         $str.=3D(0x80 | $c>>6 & 0x3F);
         $str.=3D(0x80 | $c & 0x3F);
      }
      Return $str;
   }

Function Big52Utf8($Big5){
   //Modify By MingSen Zhao

   If(!Trim($Big5)) Return $Big5;
   $tmp=3DFile("./BIG5.TXT");
   Foreach($tmp as $key =3D> $value)
      $codetable[Hexdec(Substr($value,0,6))]=3DSubstr($value,7,6);

   While($Big5){
      If(Ord(Substr($Big5,0,1))>127){

$utf8=3DU2Utf8(Hexdec($codetable[Hexdec(Bin2hex(Substr($Big5,0,2)))]));
         For($i=3D0;$i<Strlen($utf8);$i+=3D3)
            $ret.=3DChr(Substr($utf8,$i,3));
         $Big5=3DSubstr($Big5,2,Strlen($Big5));
      }Else{
         $ret.=3DSubstr($Big5,0,1);
         $Big5=3DSubstr($Big5,1,Strlen($Big5));
      }
   }
   Return $ret;
}

it need a file "big5.txt" that is a u8tob5 table.this program can be =
running correctly.but the word on map is still unreadable.It seems to =
transfer uncompletely.And the tansfer time is slowly.Are there any =
methods that can work like this and more efficiency?

thanks for your response!
