Course Introduction:PHP 中的二维数组是包含嵌套数组的集合。要创建二维数组,请使用语法:$array_name = array(array(element11, element12, ...), array(element21, element22, ...),访问数组元素:$array_namerow_index。要遍历数组,请使用嵌套循环:for ($row = 0; $row < count($array_name); $row++) { for ($column = 0; $column

Course Introduction:对于PHP数组键值互换,最优解决方案取决于具体场景。对于包含字符串键的数组,array_flip函数是最有效的方法;对于其他类型的键,可以使用foreach循环或关联数组。具体方法包括:array_flip函数:直接交换键和值。foreach循环:使用临时变量交换键和值。关联数组:将值作为键存储,将键作为值存储。

Course Introduction:在PHP中键值对调有三种最优方案:array_flip()函数可快速互换唯一键和值的数组;array_combine()函数合并两个数组形成新数组;自定义函数可用于自定义重复值处理等高级需求。最佳方案选择取决于键值唯一性、重复值数量和效率考虑。
