默認情況下php的 json_decode 方法會把特殊字符進行轉義,還會把中文轉為Unicode編碼形式。
這使得數據庫查看文本變得很麻煩。所以我們需要限制對於中文的轉義。
對於PHP5.4+版本,json_decode函數第二個參數,可以用來限制轉義范圍。
要限制中文,使用JSON_UNESCAPED_UNICODE參數。
json_encode($a, JSON_UNESCAPED_UNICODE);
例如:在保存數組中中文對應的分數時,其中包含有中文,在將數組轉換成字符串json_encode()時,加入參數
JSON_UNESCAPED_UNICODE,就可以防止中文數據被轉義。
$answer_score[0] = array("中文1" => mt_rand(95,99));//中文名稱對應的分數 $answer_score[1] = array("中文2" => mt_rand(81,87)); $answer_score[2] = array("中文3" => mt_rand(70,80)); $answer_score[3] = array("中文4" => mt_rand(70,80)); $answer_score[4] = array("中文5" => mt_rand(70,80)); $json_answer_score = (json_encode($answer_score , JSON_UNESCAPED_UNICODE)); $model = new SweepstakesModel(); $selfAnswer = $model->updateGroupxzSelfanswer("pengjun123" , "werwef" , $json_answer_score , "軍軍");
在數據庫中存儲的結果如下:
Array ( [id] => 1 [openid] => pengjun123 [nickname] => 彭軍 [icon] => http://wx.qlogo.cn/mmopen/qhDbvnE5DMn5stSjg52mmB4Tj1nMVCticRShFfBriaE8lAsF3cgzNtZGogVJXUyUOG1W6hQKFWBM8SZhEnIrTyb8LO1nc6sgQd/0 [answer] => werwef [addtime] => 2017-08-15 18:24:22 [subtime] => 2017-08-28 12:13:58 [answer_score] => [{"中文1":95},{"中文2":82},{"中文3":72},{"中文4":76},{"中文5":70}] [answer_point] => 軍軍 [extend] => 1 [help_answer_score] => [helppositionName] => )
如果不使用 JSON_UNESCAPED_UNICODE , 則會出現如下的轉義效果
Array ( [id] => 1 [openid] => pengjun123 [nickname] => 彭軍 [icon] => http://wx.qlogo.cn/mmopen/qhDbvnE5DMn5stSjg52mmB4Tj1nMVCticRShFfBriaE8lAsF3cgzNtZGogVJXUyUOG1W6hQKFWBM8SZhEnIrTyb8LO1nc6sgQd/0 [answer] => werwef [addtime] => 2017-08-15 18:24:22 [subtime] => 2017-08-28 12:21:19 [answer_score] => [{"\u4e2d\u65871":98},{"\u4e2d\u65872":87},{"\u4e2d\u65873":77},{"\u4e2d\u65874":79},{"\u4e2d\u65875":78}] [answer_point] => 軍軍 [extend] => 1 [help_answer_score] => [helppositionName] => )
這種轉義之后的數據在數據庫很難閱讀
