This is a very powerful paging class. Although it looks a bit ugly, it can be modified
As for mysql.class.php, I modified the limit method so that it can support one parameter and two parameters, which is more convenient to operate
[php] public function limit($offset,$length=null){
If (is_null($length)) {
$this->query_list['limit']='limit '.$offset;
return $this;
}else {
If(!isset($length)){
$length = $offset;
$offset = 0;
}
$this->query_list['limit'] = 'limit '.$offset.','.$length;
return $this;
}
