ThinkPHP 转换数据库查询出的数据到对应类型

use Think\Model;use Think\Model\RelationModel;class BaseModel extends RelationModel{    //在查询后,转换数据类型    protected function _after_select(&$resultSet, $options)    {        parent::_after_select($resultSet,$options);        foreach ($resultSet as &$result) {            $this->_after_find($result, $options);        }    }    protected function _after_find(&$result, $options)    {        parent::_after_find($result,$options);        foreach ($result as $field => $value) {            $this->_parseType($result, $field);        }    }}
