有时候我们会用到一个数组的键（下标）默认从0开始的需求，让我们来看例子：
1 array (size=2) 2 4 => 3 array (size=3) 4 'goods_name' => string '发放是否' (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 '是范德萨发 ' (length=16) 10 'goods_price' => string '22.00' (length=5) 11 'goods_nums' => string '113' (length=3)
使用 array_values($数组) 会把数组的键默认从下标0开始 结果：
1 array (size=2) 2 0 => 3 array (size=3) 4 'goods_name' => string '发放是否' (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 '是范德萨发 ' (length=16) 10 'goods_price' => string '22.00' (length=5) 11 'goods_nums' => string '113' (length=3)
