的var_dump $陣列的返回這樣的:爲什麼json_encode返回空括號?
array (size=3)
0 =>
object(frontend\models\Notifications)[101]
private '_attributes' (yii\db\BaseActiveRecord) =>
array (size=5)
'id' => int 1
'created_on' => string '2015-11-12 12:12:15' (length=19)
'user_id' => int 1
'text' => string '2severity level is 2guardian is 5,Student_id 2 created a Level 2 discipline issue in school' (length=91)
'is_seen' => int 0

但json_encode($陣列)返回[{},{},{}]。 我試圖: 試圖改變整個數據庫的字符編碼爲utf8_general_ci。
對於我的表,字符編碼是utf8_general_ci,因此對於表的「文本」列。可能是什麼問題?
感謝,我意識到這是一個警予模型對象。不是一個數組。你能解釋一下如何將私有屬性轉換爲'json_encodable'數組?如果你認爲這個問題是要幫助社區,你可能會考慮一個upvote :) –
但似乎你想訪問一個活躍的記錄內容..對於這個在Yii中有很多功能,而不像一個行對象訪問.. – scaisEdge
是的toArray方法做到了,但我想寫我自己的解決方案。這也將幫助我學習新的東西。不尋找一個完整的解決方案,只是一些指導如何去做到這一點。 –
