How to implement scws Chinese word segmentation search in php
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
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）
{
}

$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

$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{

How SpringBoot monitors redis Key change events
May 26, 2023 pm 01:55 PM
1. Function Overview Keyspace notification allows clients to receive events that modify Rediskey changes in some way by subscribing to channels or patterns. All commands that modify key keys. All keys that received the LPUSHkeyvalue[value…] command. All expired keys in the db database. Events are distributed through Redis's subscription and publishing functions (pub/sub), so all clients that support subscription and publishing functions can directly use the keyspace notification function without any modifications. Because the current subscription and publishing functions of Redis adopt a fireandforget strategy, if your program

How to solve the problem of batch deletion of key values in redis
May 31, 2023 am 08:59 AM
Problems encountered: During the development process, you will encounter keys that need to be deleted in batches according to certain rules, such as login_logID (ID is a variable). Now you need to delete data such as "login_log*", but redis itself only has batch query. Command keys for class key values, but there is no command for batch deletion of a certain class. Solution: Query first, then delete, use xargs to pass parameters (xargs can convert pipe or standard input (stdin) data into command line parameters), execute the query statement first, and then remove the queried key value and the original del parameters. delete. redis-cliKEYSkey* (search condition)|xargsr
