This article mainly introduces the method of implementing scws Chinese word segmentation search in PHP, details the specific steps and related usage skills of scws Chinese word segmentation search, and provides the download address of scws website. Friends who need it can refer to it

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.

How to implement scws Chinese word segmentation search in phpphp.cn.rar

) After decompression, put it in a place eg:E:/wamp/scws

2. Configure 

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

in php.ini

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）
{
}
