The example in this article describes the method of implementing scws Chinese word segmentation search in PHP. Share it with everyone for your reference, the details are as follows:

1. 4 files (download address of this site.) After unzipping, put them in a place eg: E:/wamp/scws

2. Configure in php.ini

extension = php_scws.dll 
scws.default.charset = utf8 //配置默认的编码方式
scws.default.fpath = "E:/wamp/scws" //加压后文件的路径

Copy after login

3. Use

$so = scws_new(); 
$so->set_charset('utf8'); //编码
// 这里没有调用 set_dict 和 set_rule 系统会自动试调用 ini 中指定路径下的词典和规则文件 
$so->add_dict(ini_get('scws.default.fpath') . '/dict.utf8.xdb');
//$so->add_dict('./dd.txt',SCWS_XDICT_TXT);
$so->set_rule(ini_get('scws.default.fpath') . '/rules.utf8.ini'); 
$so->set_duality(0);  //散字二元 
$so->set_ignore(0); //忽略标点符号
$so->set_multi(0); 
$wd='要搜索的内容';
$so->send_text($wd); 
while($tmp = $so->get_result())
//遍历后即得到字符串分割后的内容，
//根据得到的内容分别到数据库中查找（like匹配）
{
}

and personally tested it as follows:

function search($keywords,$table,$key1,$key2){
// (要查找的字符串,表名,字段一,字段二)如果就一个字段的话，$key2='';
 $arr=array();
 $str=array(); 
 if( preg_match("/^[^\x80-\xff]+$/", $keywords)){//判断keywords是否全为英文，全为英文的话按照字符串切割处理
 $str1=explode(' ',$keywords); //先按照空格切割
 foreach($str1 as $key=>$value)
 {
  $str2=explode(',',$value); //，切割
  foreach($str2 as $k=>$v)
  {
  $str3=explode('.',$v); //。切割
  foreach($str3 as $kk=>$vv)
  {
   array_push($arr,$vv);//处理完后，返回一个数组
  }
  }
 }
 }else{//对中文的分词处理
 $so = scws_new(); 
 $so->set_charset('utf8'); 
  // 这里没有调用 set_dict 和 set_rule 系统会自动试调用 ini 中指定路径下的词典和规则文件 
   $so->add_dict(ini_get('scws.default.fpath') . '/dict.utf8.xdb');
   $so->set_rule(ini_get('scws.default.fpath') . '/rules.utf8.ini'); 
   $so->set_duality(0);  //散字二元 
  $so->set_ignore(0); //忽略标点符号
  $so->set_multi(0);
 $so->send_text($keywords);
 while ($tmp = $so->get_result())//得到一个数组，里面包含词组和标点符号
 {
  foreach($tmp as $key=>$value)
  {
  $value=$value["word"];
  if(preg_match("/^[一-龥]{6,21}$/", $value))//去除标点符号
  {
   array_push($arr,$value);
  }
  }
 }
 }
 foreach($arr as $key=>$value)//便利得到的数组,到数据库中匹配
 {
 if($key2!='')
 {
  $sql="select * from `$table` where `$key1` like '%$value%' or `$key2` like '%$value%'";
 }else{
  $sql="select * from `$table` where `$key1` like '%$value%'";
 }
 $query=mysql_query($sql);
 array_push($str,$query);
 }
 return $str;
}
include('conn.php');
$keywords="哈哈lsd djk,hdjs dd";
$table='two_key';
$key1='address';
$key2='';
$query=search($keywords,$table,$key1,$key2);
foreach($query as $key=>$value)
{
 while($row=mysql_fetch_array($value))
 {
 echo $row[id].'----'.$row[name].'-----'.$row[address].'<br>';
 }
}
