The most common word dichotomy:

$str= ‘这是我的网站www.7di.net！‘;  //$str = iconv(‘GB2312‘,‘UTF-8‘,$str);  $result= spStr($str);  print_r($result);    /**  * UTF-8版 中文二元分词  */functionspStr($str)  {      $cstr= array();        $search = array(",", "/", "\\", ".", ";", ":", "\"", "!", "~", "`", "^", "(", ")", "?", "-", "\t", "\n", "‘", "<", ">", "\r", "\r\n", "{1}quot;", "&", "%", "#", "@", "+", "=", "{", "}", "[", "]", "：", "）", "（", "．", "。", "，", "！", "；", "“", "”", "‘", "’", "［", "］", "、", "—", "　", "《", "》", "－", "…", "【", "】",);        $str= str_replace($search, " ", $str);      preg_match_all("/[a-zA-Z]+/", $str, $estr);      preg_match_all("/[0-9]+/", $str, $nstr);        $str= preg_replace("/[0-9a-zA-Z]+/", " ", $str);      $str= preg_replace("/\s{2,}/", " ", $str);        $str= explode(" ", trim($str));        foreach($stras$s) {          $l= strlen($s);            $bf= null;          for($i= 0; $i< $l; $i=$i+3) {              $ns1 = $s{$i}.$s{$i+1}.$s{$i+2};              if(isset($s{$i+3})) {                  $ns2= $s{$i+3}.$s{$i+4}.$s{$i+5};                  if(preg_match("/[\x80-\xff]{3}/",$ns2)) $cstr[] = $ns1.$ns2;              } else if($i== 0) {                  $cstr[] = $ns1;              }          }      }        $estr= isset($estr[0])?$estr[0]:array();      $nstr= isset($nstr[0])?$nstr[0]:array();        returnarray_merge($nstr,$estr,$cstr);  }

The results are:

Array ( [0] => 7 [1] => www [2] => di [3] => net [4] => 这是 [5] => 是我 [6] => 我的 [7] => 的网 [8] => 网站 )

Next, convert the above results to the location code, the PHP code is:

foreach($resultas$s) {      $s= iconv(‘UTF-8‘,‘GB2312‘,$s);      $code[] = gbCode($s);  }  $code= implode(" ", $code);  echo$code;    functiongbCode($str) {      $return= null;        if(!preg_match("/^[\x80-\xff]{2,}$/",$str)) return$str;        $len= strlen($str);      for($i= 0; $i< $len; $i=$i+2) {          $return.= sprintf("%02d%02d",ord($str{$i})-160,ord($str{$i+1})-160);      }        return$return;  }
