test/* gb转utf8 */
function gb2utf8($gb)
{
    static $gb2utf8codetable ;    if ( function_exists('iconv') )  {
         return $message = iconv("gb2312", "UTF-8", $gb) ;
    }
    if ( ! $gb2utf8codetable ) {
          $codetablefile = file("gb2utf8",1);
          $gb2utf8codetable=array();
          while(list($key,$value)=each($codetablefile))
                $gb2utf8codetable[substr($value,0,2)]=substr($value,5,substr($value,3,1));
    }
    for($utf8=""; $gb!=''; )
    {
          if (ord(substr($gb,0,1))>127) {
              $utf8.=$gb2utf8codetable[substr($gb,0,2)];
              $gb=substr($gb,2);
          } else {
              $utf8.=substr($gb,0,1);
              $gb=substr($gb,1);
