php 代码优化

   $data = [
        'field1' => isset($params['field1']) ? $params['field1'] : 0,
        'field2' => isset($params['field2']) ? $params['field2'] : 0,,
        'field3' => isset($params['field3']) ? $params['field3'] : 0,
        'field4' => isset($params['field4']) ? $params['field4'] : 0,
        'field5' => isset($params['field5']) ? $params['field5'] : 0,
        'field6' => isset($params['field6']) ? $params['field6'] : 0,
        'field7' => isset($params['field7']) ? $params['field7'] : 1,

    ];
    
    在往数据库中插入的时候，这种代码该如何优化

 $data=array_map(function($v,$k){

   $default=0;
   if($k=='field7') $default=1;
   #return $v??$default; //php7
   return isset($v) ? $v : $default;

 },$data,array_keys($data));

$fields = array('field1'=>0, 'field2'=>'default_value');
$data = array();
foreach ($fields as $k=>$v) {
    $data[$k] = isset($params[$k]) ? $params[$k] : $v;
}
