有時候我們會用到一個數組的鍵（下標）默認從0開始的需求，讓我們來看例子：
1 array (size=2) 2 4 => 3 array (size=3) 4 'goods_name' => string '發放是否' (length=12) 5 'goods_price' => string '1111.00' (length=7) 6 'goods_nums' => string '111' (length=3) 7 5 => 8 array (size=3) 9 'goods_name' => string '是范德薩發 ' (length=16) 10 'goods_price' => string '22.00' (length=5) 11 'goods_nums' => string '113' (length=3)
使用 array_values($數組) 會把數組的鍵默認從下標0開始 結果：
1 array (size=2) 2 0 => 3 array (size=3) 4 'goods_name' => string '發放是否' (length=12) 5 'goods_price' => string '1111.00' (length=7) 6 'goods_nums' => string '111' (length=3) 7 1 => 8 array (size=3) 9 'goods_name' => string '是范德薩發 ' (length=16) 10 'goods_price' => string '22.00' (length=5) 11 'goods_nums' => string '113' (length=3)
