php实现scws中文分词搜索的方法
这篇文章主要介绍了php实现scws中文分词搜索的方法,详细介绍了scws中文分词搜索的具体步骤与相关使用技巧,并提供了scws的本站下载地址,需要的朋友可以参考下
本文实例讲述了php实现scws中文分词搜索的方法。分享给大家供大家参考，具体如下：
1、4个文件（本站下载地址。
）解压后，放到一个地方 eg:E:/wamp/scws
2、php.ini 中配置
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
3、使用
$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）
{
}亲自试验了一下如下：

$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{

return $str;

foreach($query as $key=>$value)
{
while($row=mysql_fetch_array($value))
{

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
