Recently, I used phpcms v9 to develop a personal website for the second time. I used to use 2008 to have a more comfortable function of displaying all keywords, and v9 added the keyword list function to the search. If you search for a keyword, an increase will be automatically generated. When it comes to the search_keyword table, I don’t like v9 very much about this; I think the in-site search function is generally used less, and when we add articles, we actually separate the keywords. Why do we need to do this more? In fact, It is relatively simple to change
Add a keyword_ext_model.class.php in the model folder. keyword_model actually exists in the model folder. I don’t know why there is no keyword table?
So don’t add anything based on this. Maybe this model will be used in the future.
defined('IN_PHPCMS') or exit('No permission resources.');
pc_base::load_sys_class('model', '', 0 );
class keyword_ext_model extends model {
public $table_name = '';
public function __construct() {
$this->db_config = pc_base::load_config('database');
$this->db_setting = 'default';
$this->table_name = 'keyword_ext';
parent::__construct();
}
}
?> ;
Then create a table
CREATE TABLE `t_v9_keyword_ext` (
`tagid` smallint(5) unsigned NOT NULL AUTO_INCREMENT,
`tag` char(50) NOT NULL,
`style` char(5) NOT NULL,
`usetimes` smallint(5) unsigned NOT NULL DEFAULT '0',
`lastusetime` int(10) unsigned NOT NULL DEFAULT '0',
`hits` mediumint(8) unsigned NOT NULL DEFAULT '0',
`lasthittime` int(10) unsigned NOT NULL DEFAULT '0',
`listorder` tinyint(3) unsigned NOT NULL DEFAULT '0',
`modelid` smallint(6) DEFAULT '0',
PRIMARY KEY (`tagid`),
UNIQUE KEY `tag` (`tag`),
KEY `usetimes` (`usetimes`,`listorder`),
KEY `hits` (`hits`,`listorder`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
The last step is in phpcms/modules/content/fields Add an input.inc.php in /keyword
function tags($field , $value)
{
if(!$value) return '';
if(strpos($value, ','))
{
$s = ',';
}
else
$s = ',';
}
$keywords = isset($s) ? array_unique(array_fil) ter(explode($s, $value))) : array($value);
$keyword_db = pc_base::load_model('keyword_ext_model');
foreach($keywords as $tag)
$ tag = trim($tag);
$keyword_db->delete(array("tag"=>$tag,"modelid"=>$this->modelid));
$c= $this->db->count("keywords like '%".$tag."%'");
$keyword_db->insert(array("modelid"=>$this-> modelid,"tag"=>$tag,"usetimes"=>$c,"lastusetime"=>SYS_TIME),false,true);
}
return implode($s, $keywords);
}
In this way, when keywords are added to the article, they will be automatically added to keyword_ext. When calling the site-wide tags, just adjust this table directly. Please clear the site cache first, otherwise you will not see the effect after modification.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
