Temperature: 0 °C

fetch()

式例如下:
mixed PDOStatement::fetch([int fetch_style][,int cursor_orientation[,int cursor_offset]]])

fetchAll()

式例如下:
array PDOStatement::fetchAll([int fetch_style[,int column_index]])

fetch_style控制結果的返回方式,類別如下:
PDO::FETCH_ASSOC — 關聯陣列形式
PDO::FETCH_NUM — 數字索引陣列形式
PDO::FETCH_BOTH — 兩者陣列形式都有,這是預設的
PDO::FETCH_OBJ — 按照物件的形式,類似於以前的 mysql_fetch_object()
PDO::FETCH_BOUND–以布林值的形式返回結果,同時獲取的列值賦給bindParam()方法中的指定變數。
PDO::FETCH_LAZY–以關聯陣列、數字索引陣列和物件3種形式返回結果

以上紀錄。
